+
+ <p>The Resource Description Framework (RDF) is a general-purpose language
+ for
+ representing information in the Web.</p>
+ <p>RDF Schema provides a data-modelling vocabulary for RDF data.
+ It is complemented by several companion documents which
+ describe the basic concepts and abstract stntax of RDF
+ [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>], the formal semantics of RDF [<cite><a class="bibref" href="#bib-RDF11-MT">RDF11-MT</a></cite>], and
+ various concrete syntaxes for RDF, such as Turtle [<cite><a class="bibref" href="#bib-TURTLE">TURTLE</a></cite>],
+ TriG, [<cite><a class="bibref" href="#bib-TRIG">TRIG</a></cite>], and JSON-LD [<cite><a class="bibref" href="#bib-JSON-LD">JSON-LD</a></cite>]. The RDF Primer
+ [<cite><a class="bibref" href="#bib-RDF11-PRIMER">RDF11-PRIMER</a></cite>] provides an informal introduction and
+ examples of the use of the concepts specified in this document.</p>
+ <p>This document is intended to provide a clear specification of RDF
+ Schema to those who find the formal semantics
+ specification [<cite><a class="bibref" href="#bib-RDF11-MT">RDF11-MT</a></cite>]
+ daunting. Thus, this document duplicates material also specified in the
+ RDF
+ Semantics specification. Where there is disagreement between this
+ document
+ and the RDF Semantics specification, the RDF Semantics specification
+ should
+ be taken to be correct.</p>
+
+<!--
+<p>RDF properties may be thought of as attributes of resources and inthis sense correspond to traditional attribute-value pairs. RDF
+properties also represent relationships between resources.</p>
+<p>RDF however, provides no mechanisms for describing these properties, nordoes it provide any mechanisms for describing the relationships between these
+properties and other resources. That is the role of the RDF vocabularydescription language, RDF Schema. RDF Schema defines classes and properties
+that may be used to describe classes, properties and other resources.</p>
+<p>This document does not specify a vocabulary of descriptive properties suchas "author". Instead it specifies mechanisms that may be used to name and
+describe properties and the classes of resource they describe.</p>-->
+
+ <p>
+ RDF Schema is a <a href="http://www.w3.org/TR/rdf11-mt/#semantic-extensions-and-entailment-regimes">semantic
+ extension</a> of RDF. It provides mechanisms for describing groups of
+ related resources and the relationships between these resources. RDF
+ Schema is written in RDF
+ using the terms described in this document. These resources are used to
+ determine characteristics of other resources, such as the <a href="#ch_domain">domains</a>
+ and <a href="#ch_range">ranges</a> of properties.
+ </p>
+ <p>The RDF Schema class and property system is similar to the type
+ systems of object-oriented programming languages such as Java. RDF
+ Schema differs from many such systems in that instead of defining a
+ class in
+ terms of the properties its instances may have, RDF Schema
+ describes properties in terms of the classes of
+ resource to which they apply. This is the role of the <a href="#ch_domain">domain</a>
+ and <a href="#ch_range">range</a>
+ mechanisms described in this specification. For example, we could
+ define the <code>eg:author</code> property to have a domain of <code>eg:Document</code>
+ and a range of
+ <code>eg:Person</code>, whereas a classical object oriented system might
+ typically define a class <code>eg:Book</code> with an attribute called
+ <code>eg:author</code> of type <code>eg:Person</code>. Using the RDF
+ approach, it is easy for others to subsequently define additional
+ properties with a domain of eg:<code>Document</code> or a range of
+ <code>eg:Person</code>. This can be done without the need to re-define
+ the original description of
+ these classes. One benefit of the RDF property-centric approach is that
+ it
+ allows anyone to extend the description of existing resources, one of
+ the
+ architectural principles of the Web [<cite><a class="bibref" href="#bib-BERNERS-LEE98">BERNERS-LEE98</a></cite>].</p>
+ <p>This specification does not attempt to enumerate all the possible forms

+</p>
+ <p>The language defined in this specification consists of a collection of
+ RDF resources that can be used to describe other RDF resources in
+ application-specific RDF vocabularies. The core vocabulary is defined in
+ a namespace informally called <code>rdfs</code> here. That namespace is

+ <blockquote>
+ <code>http://www.w3.org/2000/01/rdf-schema#</code>

+ <p>Resources may be divided into groups called classes. The members of a
+ class are known as <em>instances</em> of the class. Classes are
+ themselves
+ resources. They are often identified by <a href="http://www.w3.org/TR/rdf11-concepts/#section-IRIs">IRIs</a>
+ and
+ may be described using RDF properties. The <code><a href="#ch_type">rdf:type</a></code>
+ property may be used to state that a
+ resource is an instance of a class.</p>
+ <p>RDF distinguishes between a class and the set of its instances.
+ Associated
+ with each class is a set, called the class extension of the class, which
+ is
+ the set of the instances of the class. Two classes may have the same set
+ of
+ instances but be different classes. For example, the tax office may
+ define
+ the class of people living at the same address as the editor of this
+ document. The Post Office may define the class of people whose address
+ has
+ the same zip code as the address of the author. It is possible for these
+ classes to have exactly the same instances, yet to have different
+ properties.
+ Only one of the classes has the property that it was defined by the tax
+ office, and only the other has the property that it was defined by the
+ Post
+ Office.</p>
+ <p>A class may be a member of its own class extension and may be an
+ instance of itself. </p>
+ <p>The group of resources that are RDF Schema classes is itself a class
+ called <a href="#ch_class"><code>rdfs:Class</code></a>.</p>
+ <p id="def-subclass">
+ If a class C is a <em>subclass</em> of a class C', then all instances
+ of C will
+ also be instances of C'. The <a href="#ch_subclassof"><code>rdfs:subClassOf</code></a>
+ property may be used to state that one class is a subclass of another.

+ <li>Fixed incorrect pointer to RDF Primer example 16 to example 21.</li>
+ <li>Removed the introductory paragraph of Sec. <a href="#ch_reificationvocab">"Reification
+ Vocabulary"</a>, as this discussion is not related to the
+ technical content and is irrelevant and confusing now. </li>
+ <li>Update of affiliation of the editors. </li>
+ <li>Added RDF WG to the Acknowledgements section.</li>
+ <li>Renamed the document from "RDF Vocabulary Description Language
+ 1.0: RDF Schema" to "RDF Schema 1.1", as the term Vocabulary
+ Description Language has led to confusion.</li>
+ <li>Three paragraphs of the Introduction were left out. These
+ paragraphs described the things that RDF Schema does not do and are
+ now much less relevant than in 2004. </li>
+ <li>Added the datatypes <code>rdf:langString</code> and <code>rdf:HTML</code>.
+ </li>
+ <li>Removed Appendix "RDF Schema in RDF/XML". It was informative, but
+ now out of date, in terms of content and in terms of
+ syntax.</li>
+ <li>Marked <code>rdf:HTML</code> and <code>rdf:XMLLiteral</code>
+ as non-normative.</li>
+ <li>Removed references to 2004 Primer from Secs. 5.1, 5.2
+ and 5.4.3. In the latter case the example referred to was
+ moved into this document for readability purposes. </li>

+ </p>
+ <ul>
+ <li>Amended Appendix A to note that the RDF/XML description of RDF and
+ RDFS terms is not directly published at the RDFS namespace, but
+ split between the 'rdf:' and 'rdfs:' namespace documents. Also
+ removed the pre-REC warning that the WG might choose to change the

+ <li>Amended rdfs:range specification for rdf:predicate for consistency
+ with the Semantics document (previously rdf:Property; now,
+ rdfs:Resource)</li>
+ <li>Removed reference to RDF mimetypes doc, as the IETF draft has
+ expired and is 404 missing on their site.</li>
+ <li>Reification vocabulary redescribed (<a href="http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Aug/0161.html">details</a>).</li>

+ and referencing OWL, an editorial suggestion from Bijan Parsia. (<a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003AprJun/0177.html">details</a>).

+For

+have
+a

+define
+a

+</code>
+with
+an
+attribute

+<code>

+Using

+
+ <p>The RDF Concepts and Abstract Syntax document [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>]
+ defines the RDF Graph data model and the
+ RDF Graph abstract syntax.
+ Along with the RDF Semantics [<cite><a class="bibref" href="#bib-RDF11-MT">RDF11-MT</a></cite>]
+ this provides an abstract syntax with a formal semantics for it.
+ The RDF graph has <em>nodes</em>
+ and labeled directed <em>arcs</em>
+ that link pairs of nodes and this is represented as a set of
+ RDF triples
+ where each triple contains a
+ <em>subject node</em>, <em>predicate</em> and <em>object node</em>.
+ Nodes are IRIs, literals, or blank nodes.
+ Blank nodes may be given
+ a document-local identifier called a
+ blank node identifier.
+ Predicates are IRIs
+ and can be interpreted as either a relationship between the two
+ nodes or as defining an attribute value (object node) for some
+ subject node.</p>
+
+ <p>In order to encode the graph in XML, the nodes and predicates have to be
+ represented in XML terms — element names, attribute names, element contents
+ and attribute values.
+ RDF/XML uses XML
+ <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#NT-QName">QNames</a>
+ as defined in Namespaces in XML [<cite><a class="bibref" href="#bib-XML-NAMES">XML-NAMES</a></cite>] to represent IRIs.
+ All QNames have a <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#dt-NSName">namespace
+ name</a> which is an IRI
+ and a short
+ <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#NT-LocalPart">local name</a>.
+ In addition, QNames can either have a short
+ <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#NT-Prefix">prefix</a>
+ or be declared with the default namespace declaration and have none (but
+ still have a namespace name)</p>
+
+ <p>The IRI represented by a QName is determined by appending the
+ <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#NT-LocalPart">local name</a>
+ part of the QName after the
+ <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#dt-NSName">namespace
+ name</a> (IRI) part of the QName.
+ This is used to shorten the IRI
+ of all predicates and some nodes.
+ IRIs identifying
+ subject and object nodes can also be stored as XML attribute values.
+ RDF literals
+ which can only be object nodes,
+ become either XML element text content or XML attribute values.</p>
+
+ <p>A graph can be considered a collection of paths of the form node,
+ predicate arc, node, predicate arc, node, predicate arc, ... node
+ which cover the entire graph. In RDF/XML these turn into sequences of
+ elements inside elements which alternate between elements for nodes
+ and predicate arcs. This has been called a series of node/arc
+ stripes. The node at the start of the sequence turns into the
+ outermost element, the next predicate arc turns into a child element,
+ and so on. The stripes generally start at the top of an RDF/XML
+ document and always begin with nodes.
+ </p>
+
+ <p>Several RDF/XML examples are given in the following sections
+ building up to complete RDF/XML documents. <a href="#example7">Example 7</a>
+ is the first complete RDF/XML document.</p>

+
+ <p>There are several abbreviations that can be used to make common
+ uses easier to write down. In particular, it is common that a
+ subject node in the RDF graph has multiple outgoing predicate arcs. RDF/XML
+ provides an abbreviation for the corresponding syntax when a node
+ element about a resource has multiple property elements. This can be
+ abbreviated by using multiple child property elements inside the node
+ element describing the subject node.</p>
+
+ <p>Taking <a href="#example3">Example 3</a>, there are

+ The subject node with IRI
+ <code>http://www.w3.org/TR/rdf-syntax-grammar</code>
+ has property elements <code>ex:editor</code> and <code>ex:title</code>
+
+ and the node element for the blank node can take <code>ex:homePage</code>

+
+ <p>It is common for RDF graphs to have <code>rdf:type</code> predicates
+ from subject nodes. These are conventionally called <em>typed
+ nodes</em> in the graph, or <em>typed node elements</em> in the
+ RDF/XML. RDF/XML allows this triple to be expressed more concisely.
+ by replacing the <code>rdf:Description</code> node element name with
+ the namespaced-element corresponding to the
+
+ IRI of the value of
+ the type relationship. There may, of course, be multiple <code>rdf:type</code>
+ predicates but only one can be used in this way, the others must remain as
+ property elements or property attributes.
+ </p>
+
+ <p>The typed node elements are commonly used in RDF/XML with the built-in
+ classes in the <a href="#section-Namespace">RDF vocabulary</a>:
+ <code>rdf:Seq</code>, <code>rdf:Bag</code>, <code>rdf:Alt</code>,
+
+ <code>rdf:Statement</code>, <code>rdf:Property</code> and

+
+ <p>RDF/XML allows further abbreviating IRIs in XML attributes in two
+ ways. The XML Infoset provides a base URI attribute <code>xml:base</code>
+ that sets the base URI for resolving relative IRIs, otherwise
+ the base URI is that of the document. The base URI applies to
+ all RDF/XML attributes that deal with IRIs which are <code>rdf:about</code>,
+ <code>rdf:resource</code>, <code>rdf:ID</code>
+ and <code>rdf:datatype</code>.</p>
+
+ <p>The <code>rdf:ID</code> attribute on a node element (not property
+ element, that has another meaning) can be used instead of
+ <code>rdf:about</code> and gives a relative IRI equivalent to <code>#</code>
+ concatenated with the <code>rdf:ID</code> attribute value. So for
+ example if <code>rdf:ID="name"</code>, that would be equivalent
+ to <code>rdf:about="#name"</code>. <code>rdf:ID</code> provides an additional
+ check since the same <em>name</em> can only appear once in the
+ scope of an <code>xml:base</code> value (or document, if none is given),
+ so is useful for defining a set of distinct,
+ related terms relative to the same IRI.</p>

+
+ <div>
+ <p>This document specifies the syntax of RDF/XML as a grammar on an
+ alphabet of symbols. The symbols are called <em>events</em> in the
+ style of the XPATH
+ <a href="http://www.w3.org/TR/xpath#infoset">Information Set Mapping</a>.
+ A sequence of events is normally derived from an XML document, in
+ which case they are in document order as defined below in
+ <a href="#section-Infoset-Mapping">Section 6.2 Information Set Mapping</a>.
+ The sequence these events form are intended to be similar to the sequence
+ of events produced by the [<cite><a class="bibref" href="#bib-SAX">SAX</a></cite>] XML API from
+ the same XML document. Sequences of events may be checked against
+ the grammar to determine whether they are or are not syntactically
+ well-formed RDF/XML.</p>
+
+ <p>The grammar productions may include actions which fire when the
+ production is recognized. Taken together these actions define a
+ transformation from any syntactically well-formed RDF/XML sequence of
+ events into an RDF graph represented in the N-Triples [<cite><a class="bibref" href="#bib-N-TRIPLES">N-TRIPLES</a></cite>]
+ language.</p>
+
+ <p>The model given here illustrates one way to create a representation of
+ an RDF Graph
+ from an RDF/XML document. It does not mandate any implementation
+ method — any other method that results in a representation of the same
+ RDF Graph may be used.</p>
+
+ <p>In particular:</p>
+ <ul>
+ <li>This specification permits any
+ representation of an RDF graph;
+ in particular, it does not require the use of N-Triples [<cite><a class="bibref" href="#bib-N-TRIPLES">N-TRIPLES</a></cite>].</li>
+ <li>This specification does not require the use of
+ [<cite><a class="bibref" href="#bib-XPATH">XPATH</a></cite>] or [<cite><a class="bibref" href="#bib-SAX">SAX</a></cite>]</li>
+ <li>This specification places no constraints on the order in which
+ software transforming RDF/XML into a representation of a graph,
+ constructs the representation of the graph.</li>
+ <li>Software transforming RDF/XML into a representation of a graph
+ <em class="rfc2119" title="MAY">MAY</em> eliminate duplicate predicate arcs.</li>
+ </ul>
+
+ <p>The syntax does not support non-well-formed XML documents, nor
+ documents that otherwise do not have an XML Information Set; for
+ example, that do not conform to
+ Namespaces in XML [<cite><a class="bibref" href="#bib-XML-NAMES">XML-NAMES</a></cite>].
+ </p>
+
+ <p>The Infoset requires support for
+ XML Base [<cite><a class="bibref" href="#bib-XMLBASE">XMLBASE</a></cite>].
+ RDF/XML uses the information item property [base URI], discussed in
+ <a href="#section-baseURIs">section 5.3</a>
+ </p>
+
+ <p>This specification requires an
+ XML Information Set [<cite><a class="bibref" href="#bib-XML-INFOSET">XML-INFOSET</a></cite>]
+ which supports at least the following information items and
+ properties for RDF/XML:</p>
+

+ <dd>[character code]</dd>
+ </dl>
+
+ <p>There is no mapping of the following items to data model events:</p>
+ <ul>
+ <li><a href="http://www.w3.org/TR/xml-infoset/#infoitem.pi">processing instruction information item</a></li>

+ </ul>
+
+ <p>Other information items and properties have no mapping to
+ syntax data model events.
+ </p>
+
+ <p>Element information items with reserved XML Names
+ (See <a href="http://www.w3.org/TR/2000/REC-xml-20001006#dt-name">Name</a>
+ in <a href="http://www.w3.org/TR/2000/REC-xml-20001006">XML 1.0</a>)
+ are not mapped to data model element events. These are all those

+ independent comparison) and all those with [prefix] property
+ having no value and which have [local name] beginning with
+
+ <code>xml</code> (case independent comparison).
+ </p>
+
+ <p>All information items contained inside XML elements matching the

+ The RDF/XML grammar is defined in terms of mapping from these matched

+ <blockquote>
+ <div class="productionOuter"><div class="productionInner"><p>
+ number <em>event-type</em> <em>event-content</em>

+ </div>
+ </blockquote>
+
+ <p>where the <em>event-content</em> is an expression matching
+
+ <em>event-types</em> (as defined in <a href="#section-Nodes">Section 6.1</a>),
+ using notation given in the following sections.
+ The number is used for reference purposes.

+ <p>If the RDF/XML is a standalone XML document
+ (identified by presentation as an
+ application/rdf+xml <a href="#section-MIME-Type">RDF MIME type</a> object,

+ production <a href="#doc">doc</a> or
+ production <a href="#nodeElement">nodeElement</a>.</p>
+
+ <p>If the content is known to be RDF/XML by context, such as when
+ RDF/XML is embedded inside other XML content, then the grammar
+ can either start
+ at <a href="#section-element-node">Element Event</a>
+ <a href="#RDF">RDF</a>
+ (only when an element is legal at that point in the XML)
+ or at production <a href="#nodeElementList">nodeElementList</a>
+ (only when element content is legal, since this is a list of elements).
+ For such embedded RDF/XML, the
+ <a class="termref" href="#eventterm-element-base-uri"><span class="arrow">·</span>base-uri<span class="arrow">·</span></a>
+ value on the outermost element must be initialized from the containing
+ XML since no

+Completing

+Declaration
+</h3>
+<p>
+To
+create
+a
+complete
+RDF/XML
+document,
+the
+serialization
+of
+the
+graph
+into
+XML
+is
+usually
+contained
+inside
+an
+<code>
+rdf:RDF
+</code>
+XML
+element
+which
+becomes
+the
+top-level
+XML
+document
+element.
+Conventionally
+the
+<code>
+rdf:RDF
+</code>
+element
+is
+also
+used
+to
+declare
+the
+XML
+namespaces
+that
+are
+used,
+although
+that
+is
+not
+required.
+When
+there
+is
+only
+one
+top-level
+node
+element
+inside
+<code>
+rdf:RDF
+</code>,
+the
+<code>
+rdf:RDF
+</code>
+can
+be
+omitted
+although
+any
+XML
+namespaces
+must
+still
+be
+declared.
+</p>
+<p>
+The
+XML
+specification
+also
+permits
+an
+XML
+declaration
+at
+the
+top
+of
+the
+document
+with
+the
+XML
+version
+and
+possibly
+the

+encoding.
+This
+is
+optional
+but
+recommended.

+It

+RDF/XML
+allows

+
+ <p><a href="http://www.w3.org/TR/rdf11-concepts/#dfn-literal">Literals</a> are used to identify values such as strings, numbers, dates.</p>
+
+
+ <p>
+ Literals (Grammar production <a href="#grammar-production-literal">Literal</a>) have a lexical form followed by a language tag, a datatype IRI, or neither.
+ The representation of the lexical form consists of an initial delimiter <code>"</code> (<span class="codepoint">U+0022</span>), a sequence of permitted characters or numeric escape sequence or string escape sequence, and a final delimiter. Literals may not contain the characters <code>"</code>, <code title="LINE FEED"><sub>LF</sub></code>, or <code title="CARRIAGE RETURN"><sub>CR</sub></code>. In addition '<code>\</code>' (<span class="codepoint">U+005C</span>) may not appear in any quoted literal except as part of an escape sequence.
+ The corresponding <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-lexical-form">RDF lexical form</a> is the characters between the delimiters, after processing any escape sequences.
+ If present, the <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string">language tag</a> is preceded by a '<code>@</code>' (<span class="codepoint">U+0040</span>).
+ If there is no language tag, there may be a <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-datatype-iri">datatype IRI</a>, preceeded by '<code>^^</code>' (<span class="codepoint">U+005E</span> <span class="codepoint">U+005E</span>). If there is no datatype IRI and no language tag, the datatype is <code>xsd:string</code>.

+ <p>
+ <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-blank-node">RDF blank nodes</a> in N-Quads are expressed as <code>_:</code> followed by a blank node label which is a series of name characters.
+ The characters in the label are built upon <a href="#grammar-production-PN_CHARS_BASE">PN_CHARS_BASE</a>, liberalized as follows:
+ </p>
+ <ul>
+ <li>The characters <code>_</code> and digits may appear anywhere in a blank node label.</li>
+ <li>The character <code>.</code> may appear anywhere except the first or last character.</li>
+ <li>The characters <code>-</code>, <code>U+00B7</code>, <code>U+0300</code> to <code>U+036F</code> and <code>U+203F</code> to <code>U+2040</code> are permitted anywhere except the first character.</li>
+ </ul>
+ <p>
+ A fresh RDF blank node is allocated for each unique blank node label in a document.
+ Repeated use of the same blank node label identifies the same RDF blank node.

+ </dl>
+ <p>The Internet Media Type / MIME Type for N-Quads is "application/n-quads".</p>
+ <p>It is recommended that N-Quads files have the extension ".nq" (all lowercase) on all platforms.</p>
+
+ <p>It is recommended that N-Quads files stored on Macintosh HFS file systems be given a file type of "TEXT".</p>
+ <p>This information that follows will be submitted to the IESG for review, approval, and registration with IANA.</p>
+ <dl>
+ <dt>Type name:</dt>

+ <dd>n-quads</dd>
+ <dt>Required parameters:</dt>
+ <dd>None</dd>
+ <dt>Optional parameters:</dt>
+ <dd>None</dd>
+
+ <dt>Encoding considerations:</dt>
+ <dd>The syntax of N-Quads is expressed over code points in Unicode [<cite><a class="bibref" href="#bib-UNICODE">UNICODE</a></cite>]. The encoding is always UTF-8 [<cite><a class="bibref" href="#bib-UTF-8">UTF-8</a></cite>].</dd>
+ <dd>Unicode code points may also be expressed using an \uXXXX (U+0 to U+FFFF) or \UXXXXXXXX syntax (for U+10000 onwards) where X is a hexadecimal digit [0-9A-F]</dd>
+ <dt>Security considerations:</dt>
+ <dd>N-Quads is a general-purpose assertion language; applications may evaluate given data to infer more assertions or to dereference IRIs, invoking the security considerations of the scheme for that IRI. Note in particular, the privacy issues in [<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10 for HTTP IRIs. Data obtained from an inaccurate or malicious data source may lead to inaccurate or misleading conclusions, as well as the dereferencing of unintended IRIs. Care must be taken to align the trust in consulted resources with the sensitivity of the intended use of the data; inferences of potential medical treatments would likely require different trust than inferences for trip planning.</dd>
+
+ <dd>N-Quads is used to express arbitrary application data; security considerations will vary by domain of use. Security tools and protocols applicable to text (e.g. PGP encryption, MD5 sum validation, password-protected compression) may also be used on N-Quads documents. Security/privacy protocols must be imposed which reflect the sensitivity of the embedded information.</dd>
+ <dd>N-Quads can express data which is presented to the user, for example, RDF Schema labels. Application rendering strings retrieved from untrusted N-Quads documents must ensure that malignant strings may not be used to mislead the reader. The security considerations in the media type registration for XML ([<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10) provide additional guidance around the expression of arbitrary data and markup.</dd>
+ <dd>N-Quads uses IRIs as term identifiers. Applications interpreting data expressed in N-Quads should address the security issues of
+ <a href="http://www.ietf.org/rfc/rfc3987.txt" class="norm">Internationalized Resource Identifiers (IRIs)</a> [<cite><a class="bibref" href="#bib-RFC3987">RFC3987</a></cite>] Section 8, as well as
+ <a href="http://www.ietf.org/rfc/rfc3986.txt" class="norm">Uniform Resource Identifier (URI): Generic Syntax</a> [<cite><a class="bibref" href="#bib-RFC3986">RFC3986</a></cite>] Section 7.</dd>
+
+ <dd>Multiple IRIs may have the same appearance. Characters in different scripts may
+ look similar (a Cyrillic "о" may appear similar to a Latin "o"). A character followed
+ by combining characters may have the same visual representation as another character
+ (LATIN SMALL LETTER E followed by COMBINING ACUTE ACCENT has the same visual representation
+ as LATIN SMALL LETTER E WITH ACUTE).
+
+<!-- (<code>foo:resum鼯code> and <code>fоо:resumé</code>)-->
+
+ Any person or application that is writing or interpreting data in Turtle must take care to use the IRI that matches the intended semantics, and avoid IRIs that make look similar.
+ Further information about matching of similar characters can be found
+ in <a href="http://www.unicode.org/reports/tr36/" class="inform">Unicode Security
+ Considerations</a> [<cite><a class="bibref" href="#bib-UNICODE-SECURITY">UNICODE-SECURITY</a></cite>] and

+<h2 id="extensions" aria-level="1" role="heading"><span class="secno">3. </span>Semantic Extensions and Entailment Regimes</h2>
+ <p>RDF is intended for use as a base notation for a variety of extended notations such as OWL [<cite><a class="bibref" href="#bib-OWL2-OVERVIEW">OWL2-OVERVIEW</a></cite>] and RIF [<cite><a class="bibref" href="#bib-RIF-OVERVIEW">RIF-OVERVIEW</a></cite>], whose expressions can be encoded as RDF graphs which use a particular vocabulary with a specially defined meaning. Also, particular IRI vocabularies may be given meanings by other specifications or conventions. When such extra meanings are assumed, a given RDF graph may support more extensive entailments than are sanctioned by the basic RDF semantics. In general, the more assumptions that are made about the meanings of IRIs in an RDF graph, the more entailments follow from those assumptions. </p>
+
+<p>A particular such set of semantic assumptions is called a <dfn id="dfn-semantic-extension">semantic extension</dfn>. Each <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a> defines an <dfn id="dfn-entailment-regime">entailment regime</dfn> (used here in the same sense as in the SPARQL 1.1 Entailment Regime recommendation [<cite><a class="bibref" href="#bib-SPARQL11-ENTAILMENT">SPARQL11-ENTAILMENT</a></cite>] ) of entailments which are valid under that extension. RDFS, described later in this document, is one such <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a>. We will refer to entailment regimes by names such as <em> RDFS entailment</em>, <em>D-entailment</em>, etc. </p>
+
+<p><a href="#dfn-semantic-extension" class="internalDFN">Semantic extension</a>s <em class="rfc2119" title="MAY">MAY</em> impose special syntactic conditions or restrictions upon RDF graphs, such as requiring certain triples to be present, or prohibiting particular combinations of IRIs in triples, and <em class="rfc2119" title="MAY">MAY</em> consider RDF graphs which do not conform to these conditions to be errors. For example, RDF statements of the form <br /><br /> <code>ex:a rdfs:subClassOf "Thing"^^xsd:string .</code><br /><br /> are prohibited in the OWL <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a> based on description logics [<cite><a class="bibref" href="#bib-OWL2-SYNTAX">OWL2-SYNTAX</a></cite>]. In such cases, basic RDF operations such as taking a subset of triples, or combining RDF graphs, may cause syntax errors in parsers which recognize the extension conditions. None of the <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a>s normatively defined in this document impose such syntactic restrictions on RDF graphs.</p>
+

+An <dfn id="dfn-interpretation">interpretation</dfn> is a mapping from IRIs and literals into a set, together with some constraints upon the set and the mapping. This document defines various notions of interpretation, each corresponding in a standard way to an entailment regime. These are identified by prefixes such as <em>simple interpretation</em>, etc., and are defined in later sections. The unqualified term <em>interpretation</em> is usually used to refer to any compatible kind of interpretation in general, but if clear from the context might refer to a specific kind of interpretation.
+</p><p>
+
+</p><p>The words <dfn id="dfn-denote">denote</dfn><strong>s</strong> and <dfn id="dfn-refers-to">refers to</dfn> are used interchangeably as synonyms for the relationship between an IRI or literal and what it refers to in a given interpretation, itself called the <dfn id="dfn-denotation">denotation</dfn> or <dfn id="dfn-referent">referent</dfn>. IRI meanings may also be determined by other constraints external to the RDF semantics; when we wish to refer to such an externally defined naming relationship, we will use the word <dfn id="dfn-identify">identify</dfn> and its cognates. For example, the fact that the IRI <code>http://www.w3.org/2001/XMLSchema#decimal</code> is widely used as the name of a datatype described in the XML Schema document [<cite><a class="bibref" href="#bib-XMLSCHEMA11-2">XMLSCHEMA11-2</a></cite>] might be described by saying that the IRI <em>identifies</em> that datatype. If an IRI identifies something it may or may not refer to it in a given interpretation, depending on how the semantics is specified. For example, an IRI used as a graph name <a href="#dfn-identify" class="internalDFN">identify</a>ing a named graph in an <a class="external" href="http://www.w3.org/TR/rdf11-concepts/#section-dataset">RDF dataset</a> may refer to something different from the graph it identifies. </p>
+
+<p>Throughout this document, the equality sign = indicates strict identity. The statement "A = B" means that there is one entity to which both expressions "A" and "B" refer. Angle brackets < x, y > are used to indicate an ordered pair
+ of x and y.</p>
+
+<p>Throughout this document, <a href="#dfn-rdf-graph" class="internalDFN">RDF graph</a>s and other fragments of RDF abstract syntax are written using the notational conventions of the Turtle syntax [<cite><a class="bibref" href="#bib-TURTLE">TURTLE</a></cite>]. The namespace prefixes <code>rdf:</code> <code>rdfs:</code> and <code>xsd:</code> are used as in [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>], <a href="http://www.w3.org/TR/rdf11-concepts/#vocabularies">section 1.4</a>. When the exact IRI does not matter, the prefix <code>ex:</code> is used. When stating general rules or conditions we use three-character variables such as aaa, xxx, sss to indicate arbitrary IRIs, literals, or other components of RDF syntax. Some cases are illustrated by node-arc diagrams showing the graph structure directly.</p>
+
+<p>A <dfn id="dfn-name">name</dfn> is any IRI or literal. A typed literal contains
+ two <a href="#dfn-name" class="internalDFN">name</a>s: itself and its internal type
+ IRI. A <dfn id="dfn-vocabulary">vocabulary</dfn> is a set of <a href="#dfn-name" class="internalDFN">name</a>s.
+</p>
+
+<p>The <dfn id="dfn-empty-graph">empty graph</dfn> is the empty set of triples. </p>
+<p>A <dfn id="dfn-subgraph">subgraph</dfn> of an RDF graph is a subset
+ of the triples in the graph. A triple is identified with the singleton set
+ containing it, so that each triple in a graph is considered to be a subgraph.
+ A <dfn id="dfn-proper-subgraph">proper subgraph</dfn> is a proper subset of the triples in the graph. </p>
+
+
+<p>A <dfn id="dfn-ground">ground</dfn> RDF graph is one that contains no blank
+ nodes.</p>
+
+<p>Suppose that M is a functional mapping from a set of blank
+ nodes to some set of literals, blank nodes and IRIs. Any graph obtained
+ from a graph G by replacing some or all of the blank nodes N in G by M(N) is
+ an <dfn id="dfn-instance">instance</dfn> of G. Any graph is an instance of itself,
+ an instance of an instance of G is an instance of G,
+ and if H is an instance of G then every triple in H is an instance of at least one triple
+ in G.</p>
+<p>An <dfn id="dfn-instance-with-respect-to">instance with respect to</dfn> a vocabulary
+ V is an <a href="#dfn-instance" class="internalDFN">instance</a> in which all the
+ <a href="#dfn-name" class="internalDFN">name</a>s in the instance that were substituted
+ for blank nodes in the original are <a href="#dfn-name" class="internalDFN">name</a>s
+ from V.</p>
+<p>A <dfn id="dfn-proper-instance">proper instance</dfn> of a graph
+ is an <a href="#dfn-instance" class="internalDFN">instance</a> in which a blank node has been replaced by a <a href="#dfn-name" class="internalDFN">name</a>, or two blank
+ nodes in the graph have been mapped into the same node in the instance. </p>
+<p>Two graphs are <a href="http://www.w3.org/TR/rdf11-concepts/#graph-isomorphism" class="externalDFN">isomorphic</a> when each maps into the other by a 1:1 mapping on blank nodes. Isomorphic graphs are mutual instances with an invertible instance
+ mapping. As blank nodes have no particular identity beyond their location in a graph, we will often treat isomorphic graphs as identical.</p>
+
+<p>An RDF graph is <dfn id="dfn-lean">lean</dfn> if it has no instance which is
+ a proper subgraph of itself. Non-lean graphs have internal redundancy
+ and express the same content as their lean subgraphs. For example, the graph</p>
+<p><code>ex:a ex:p _:x .<br />
+ _:y ex:p _:x .</code></p>
+<p>is not lean, but</p>
+<p><code>ex:a ex:p _:x .<br />
+ _:x ex:p _:x .</code></p>
+<p>is lean. <a href="#dfn-ground" class="internalDFN">Ground</a> graphs are lean. </p>

+<p>
+Graphs share blank nodes only if they are derived from graphs
+described by documents or other structures (such as an RDF dataset) that explicitly provide for the sharing of blank nodes between different RDF graphs. Simply downloading a
+web document does not mean that the blank nodes in a resulting RDF
+graph are the same as the blank nodes coming from other downloads of
+the same document or from the same <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-rdf-source" class="externalDFN">RDF source</a>.</p>
+
+<p> RDF applications which manipulate concrete syntaxes for RDF which use blank node identifiers should take care to keep track of the identity of the blank nodes they identify. Blank node identifiers often have a local scope, so when RDF from different sources is combined, identifiers may have to be changed in order to avoid accidental conflation of distinct blank nodes.</p>
+<p> For example, two documents may both use the blank node identifier "<code>_:x</code>" to identify a blank node, but unless these documents are in a shared identifier scope or are derived from a common source, the occurrences of "<code>_:x</code>" in one document will identify a different blank node than the one in the graph described by the other document. When graphs are formed by combining RDF from multiple sources, it may be necessary to <dfn id="dfn-standardize">standardize</dfn> apart the blank node identifiers by replacing them by others which do not occur in the other document(s). For example, the two graphs represented by the following texts: </p>
+<p><code>ex:a ex:p _:x . </code><br /><br />
+<img alt="Graph 1" src="RDF11SemanticsDiagrams/example1.jpg" /></p>
+<p><code>ex:b ex:q _:x . </code><br /><br />
+<img alt="Graph 2" src="RDF11SemanticsDiagrams/example2.jpg" /></p>
+
+<p>contain four nodes. Their union would therefore also contain four nodes:</p>
+
+<p><img alt="Union Graph" src="RDF11SemanticsDiagrams/example4.jpg" /></p>
+
+<p> However, the document formed by simply concatenating these textual surface representations: </p>
+
+<p><code>ex:a ex:p _:x .<br />
+ex:b ex:q _:x .</code><br /></p>
+
+<p>describes a graph containing three nodes:</p>
+<p><img alt="Incorrect Union Graph" src="RDF11SemanticsDiagrams/example3.jpg" /></p>
+<p> since the two occurrences of the blank node identifier "<code>_:x</code>" occurring in a common identifier scope identify the same blank node. The four-node union of these two graphs is more properly described by a surface form such as:</p>
+<p><code>ex:a ex:p _:x1 .<br />
+ex:b ex:q _:x2 .</code></p>
+
+<p>in which the blank node identifiers have been <a href="#dfn-standardize" class="internalDFN">standardize</a>d apart to avoid conflating the distinct blank nodes. (The particular blank node identifiers used have no significance, only that they are distinct.) </p>
+
+<p>It is possible for two or more graphs to share a blank node, for example if they are subgraphs of a single larger graph or derived from a common source. In this case, the union of a set of graphs preserves the identity of blank nodes shared between the graphs. In general, the union of a set of RDF graphs accurately represents the same semantic content as the graphs themselves, whether or not they share blank nodes. </p>
+<p>A related operation, called <dfn id="dfn-merging">merging</dfn>, takes the union after forcing any shared blank nodes, which occur in more than one graph, to be distinct in each graph. The resulting graph is called the <dfn id="dfn-merge">merge</dfn>. The merge of subgraphs of a graph may be larger than the original graph. For example, the result of merging the two singleton subgraphs of the three-node graph</p>
+
+<p><img alt="Three-node Graph" src="RDF11SemanticsDiagrams/example3.jpg" /></p>
+
+<p>is the four-node graph</p>
+
+<p><img alt="Four-node Graph" src="RDF11SemanticsDiagrams/example4.jpg" /></p>
+
+<p>The union is always an instance of the merge. If graphs have no blank nodes in common, then their merge and union are identical. </p>

+<p class="changenote">The 2004 RDF 1.0 semantics defined simple interpretations relative to a vocabulary.<br /><br />In the 2004 RDF 1.0 semantics, IL was a total, rather than partial, mapping.<br /><br /> The 2004 RDF 1.0 specification divided literals into 'plain' literals with no type and optional language tags, and typed literals. Usage has shown that it is important that every literal have a type. RDF 1.1 replaces plain literals without language tags by literals typed with the XML Schema <code>string</code> datatype, and introduces the special type <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string"><code>rdf:langString</code></a> for language-tagged strings. The full semantics for typed literals is given in the next section. </p>
+
+<p class="technote"> Simple interpretations are required to interpret all <a href="#dfn-name" class="internalDFN">name</a>s, and are therefore infinite. This simplifies the exposition. However, RDF can be interpreted using finite structures, supporting decidable algorithms. Details are given in Appendix B. </p>

+<p>The distinction between IR and IL will become significant below when the semantics of datatypes are defined. IL is allowed to be partial because some literals may fail to have a referent. </p>
+
+<p class="technote">
+It is conventional to map a relation name to a relational extension directly. This however presumes that the vocabulary is segregated into relation names and individual names, and RDF makes no such assumption. Moreover, RDF allows an IRI to be used as a relation name applied to itself as an argument. Such self-application structures are used in RDFS, for example. The use of the IEXT mapping to distinguish the relation as an object from its relational extension accommodates both of these requirements. It also provides for a notion of RDFS 'class' which can be distinguished from its set-theoretic extension. A similar technique is used in the ISO/IEC Common Logic standard [<cite><a class="bibref" href="#bib-ISO24707">ISO24707</a></cite>].

+ <p>The denotation of a ground RDF graph in a simple interpretation I is then given by the following

+
+
+<p> If IL(E) is undefined for some literal E then E has no semantic value, so any triple containing it will be false, so any graph containing that triple will also be false.</p>
+<p> The final condition implies that the empty graph (the empty set of triples) is always true.</p>
+<p>The sets IP and IR may overlap, indeed IP can be a subset of IR. Because of the domain conditions on IEXT, the denotation of the subject and object of any true triple will be in IR; so any IRI which occurs in a graph both as a predicate and as a subject or object will denote something in the intersection of IP and IR.</p>
+
+<p><a href="#dfn-semantic-extension" class="internalDFN">Semantic extension</a>s may impose further constraints upon interpretation mappings by requiring some IRIs to refer in particular ways. For example, D-interpretations, described below, require some IRIs, understood as <a href="#dfn-identify" class="internalDFN">identify</a>ing and referring to datatypes, to have a fixed denotation. </p>

+
+<p>Blank nodes are treated as simply indicating the existence of a thing, without using an IRI to <a href="#dfn-identify" class="internalDFN">identify</a> any particular thing. This is not the same as assuming that the blank node indicates an 'unknown' IRI.
+</p>
+
+<p> Suppose I is a simple interpretation and A is a mapping from a set of blank nodes to the universe IR of I. Define the mapping [I+A] to be I on <a href="#dfn-name" class="internalDFN">name</a>s, and A on blank nodes on the set: [I+A](x)=I(x) when x is a <a href="#dfn-name" class="internalDFN">name</a> and [I+A](x)=A(x) when x is a blank node; and extend this mapping to triples and RDF graphs using the rules given above for ground graphs.

+
+<p> The semantics for blank nodes are stated in terms of the truth of a graph. However, when two (or more) graphs share a blank node, their meaning is not fully captured by treating them in isolation. For example, consider the overlapping graphs</p>
+<p><img alt="Overlapping Graphs" src="RDF11SemanticsDiagrams/example5.jpg" /></p>
+<p> and a simple interpretation I over the universe {Alice, Bob, Monica, Ruth} with:<br />
+I(<code>ex:Alice</code>)=Alice, I(<code>ex:Bob</code>)=Bob, IEXT(I(<code>ex:hasChild</code>))={<Alice,Monica>,<Bob,Ruth> }<br /></p>
+<p>Each of the inner graphs is true under this interpretation, but the two of them together is not, because the three-node graph says that Alice and Bob have a child together. In order to capture the full meaning of graphs sharing a blank node, it is necessary to consider the union graph containing all the triples which contain the blank node.</p>
+<p class="technote"> RDF graphs can be viewed as conjunctions of simple atomic sentences in first-order logic, where blank nodes are free variables which are understood to be existential. Taking the union of two graphs is then analogous to syntactic conjunction in this syntax. RDF syntax has no explicit variable-binding quantifiers, so the truth conditions for any RDF graph treat the free variables in that graph as existentially quantified in that graph. Taking the union of graphs which share a blank node changes the implied quantifier scopes.

+
+<p>Following standard terminology, we say that I (simply) <dfn id="dfn-satisfies">satisfies</dfn> E when I(E)=true, that E is (simply) <dfn id="dfn-satisfiable">satisfiable</dfn> when a simple interpretation exists which satisfies it, otherwise (simply) <dfn id="dfn-unsatisfiable">unsatisfiable</dfn>, and that a graph G simply <dfn id="dfn-entail">entail</dfn><strong>s</strong> a graph E when every interpretation which satisfies G also satisfies E. If two graphs E and F each entail the other then they are logically <dfn id="dfn-equivalent">equivalent</dfn>.</p>
+<p>In later sections these notions will be adapted to other classes of interpretations, but throughout this section 'entailment' should be interpreted as meaning simple entailment.
+</p>
+
+<p class="technote">We do not define a notion of entailment between sets of graphs. To determine whether a set of graphs entails a graph, the graphs in the set must first be combined into one graph, either by taking the union or the merge of the graphs. Unions preserve the common meaning of shared blank nodes, while merging effectively ignores any sharing of blank nodes. Merging the set of graphs produces the same definition of entailment by a set that was defined in the 2004 RDF 1.0 specification.</p>
+
+ <p>Any process which constructs a graph E from
+ some other graph S is (simply) <dfn id="dfn-valid">valid</dfn> if S
+ simply entails E in every case, otherwise <dfn id="dfn-invalid.x">invalid.</dfn></p>
+
+<p>The fact that an inference is valid should not be understood as meaning that any RDF application is obliged or required to make the inference. Similarly, the logical invalidity of some RDF transformation or process does not mean that the process is incorrect or prohibited. Nothing in this specification requires or prohibits any particular operations on RDF graphs or sources. Entailment and validity are concerned solely with establishing the conditions on such operations which guarantee the preservation of truth. While logically invalid processes, which do not follow valid entailments, are not prohibited, users should be aware that they may be at risk of introducing falsehoods into true RDF data. Nevertheless, particular uses of logically invalid processes may be justified and appropriate for data processing under circumstances where truth can be ensured by other means. </p>
+
+<p>Entailment refers only to the truth of RDF graphs, not to their suitability for any other purpose. It is possible for an RDF graph to be fitted for a given purpose and yet validly entail another graph which is not appropriate for the same purpose. An example is the RDF test cases manifest [<cite><a class="bibref" href="#bib-RDF-TESTCASES">RDF-TESTCASES</a></cite>] which is provided as an RDF document for user convenience. This document lists examples of correct entailments by describing their antecedents and conclusions. Considered as an RDF graph, the manifest simply entails a subgraph which omits the antecedents, and would therefore be incorrect if used as a test case manifest. This is not a violation of the RDF semantic rules, but it shows that the property of <em> "being a correct RDF test case manifest"</em> is not preserved under RDF entailment, and therefore cannot be described as an RDF <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a>. Such entailment-risky uses of RDF should be restricted to cases, as here, where it is obvious to all parties what the intended special restrictions on entailment are, in contrast with the more normal case of using RDF for the open publication of data on the Web.</p>

+<p><a class="externaldefinition internalDFN" href="#dfn-skolemization"><dfn id="dfn-skolemization">Skolemization</dfn></a> is a transformation on RDF graphs which eliminates blank nodes by replacing them with "new" IRIs, which means IRIs which are coined for this purpose and are therefore guaranteed to not occur in any other RDF graph (at the time of creation). See <a href="http://www.w3.org/TR/rdf11-concepts/#section-skolemization">Section 3.5</a> of [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>] for a fuller discussion. </p>
+<p> Suppose G is a graph containing blank nodes and sk is a skolemization mapping from the blank nodes in G to the skolem IRIs which are substituted for them, so that sk(G) is a skolemization of G. Then the semantic relationship between them can be summarized as follows. </p>
+
+<p class="fact"> sk(G) simply entails G (since sk(G) is an instance of G.)</p>
+<p class="fact"> G does not simply entail sk(G) (since sk(G) contains IRIs not in G.) </p>
+<p class="fact"> For any graph H, if sk(G) simply entails H then there is a graph H' such that G entails H' and H=sk(H') . </p>
+<p class="fact"> For any graph H which does not contain any of the "new" IRIs introduced into sk(G), sk(G) simply entails H if and only if G simply entails H.
+</p>
+
+<p>The second property means that a graph is not logically <a href="#dfn-equivalent" class="internalDFN">equivalent</a> to its skolemization. Nevertheless, they are in a strong sense almost interchangeable, as shown the next two properties. The third property means that even when conclusions are drawn from the skolemized graph which do contain the new vocabulary, these will exactly mirror what could have been derived from the original graph with the original blank nodes in place. The replacement of blank nodes by IRIs does not effectively alter what can be validly derived from the graph, other than by giving new names to what were formerly anonymous entities. The fourth property, which is a consequence of the third, clearly shows that in some sense a skolemization of G can "stand in for" G as far as entailments are concerned. Using sk(G) instead of G will not affect any entailments which do not involve the new skolem vocabulary. </p>

+<h2 id="datatypes" aria-level="1" role="heading"><span class="secno">7. </span>Literals and datatypes</h2>
+<p class="changenote"> In the 2004 RDF 1.0 specification, datatype D-entailment was defined as a <a href="#dfn-semantic-extension" class="internalDFN">semantic extension</a> of RDFS-entailment. Here it is defined as a direct extension to basic RDF. This is more in conformity with actual usage, where RDF with datatypes is widely used without the RDFS vocabulary. If there is a need to distinguish this from the 2004 RDF 1.0 terminology, the longer phrasing "simple D-entailment" or "simple datatype entailment" should be used rather than "D-entailment". </p>
+
+<p> Datatypes are <a title="identify" href="#dfn-identify" class="internalDFN">identified</a> by IRIs. Interpretations will vary according to which IRIs are recognized as denoting datatypes. We describe this using a parameter D on simple interpretations, where D is the set of <dfn id="dfn-recognize">recognize</dfn><em><strong>d</strong></em> datatype IRIs. </p>
+
+<p class="changenote">The previous version of this specification defined the parameter D as a <a href="#dfn-datatype-map" class="internalDFN">datatype map</a> from IRIs to datatypes, i.e. as a restricted kind of interpretation mapping. As the current semantics presumes that a recognized IRI identifies a unique datatype, this IRI-to-datatype mapping is globally unique and externally specified, so we can think of D as either a set of IRIs or as a fixed <a href="#dfn-datatype-map" class="internalDFN">datatype map</a>. Formally, the <dfn id="dfn-datatype-map">datatype map</dfn> corresponding to the set D is the restriction of a <a href="#dfn-d-interpretation" class="internalDFN">D-interpretation</a> to the set D. Semantic extensions which are stated in terms of conditions on <a href="#dfn-datatype-map" class="internalDFN">datatype map</a>s can be interpreted as applying to this mapping. </p>
+
+<p>The exact mechanism by which an IRI <a title="identify" href="#dfn-identify" class="internalDFN">identifies</a> a datatype IRI is considered to be external to the semantics, but the semantics presumes that a recognized IRI <a title="identify" href="#dfn-identify" class="internalDFN">identifies</a> a unique datatype wherever it occurs. RDF processors which are not able to determine which datatype is identified by an IRI cannot <a href="#dfn-recognize" class="internalDFN">recognize</a> that IRI, and should treat any literals with that IRI as their datatype IRI as unknown names. </p>
+
+<p>RDF literals and datatypes are fully described in <a href="http://www.w3.org/TR/rdf11-concepts/#section-Datatypes"> Section 5</a> of [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>]. In summary: with one exception, RDF literals combine a string and an IRI <a href="#dfn-identify" class="internalDFN">identify</a>ing a datatype. The exception is <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string">language-tagged strings</a>, which have two syntactic components, a string and a language tag, and are assigned the type <code>rdf:langString</code>. A datatype is understood to define a partial mapping, called the <dfn id="dfn-lexical-to-value-mapping">lexical-to-value mapping</dfn>, from a lexical space (a set of character strings) to values. The function <dfn id="dfn-l2v">L2V</dfn> maps datatypes to their lexical-to-value mapping. A literal with datatype d denotes the value obtained by applying this mapping to the character string sss: L2V(d)(sss). If the literal string is not in the lexical space, so that the lexical-to-value mapping gives no value for the literal string, then the literal has no referent. The <dfn id="dfn-value-space">value space</dfn> of a datatype is the range of the <a href="#dfn-lexical-to-value-mapping" class="internalDFN">lexical-to-value mapping</a>. Every literal with that type either refers to a value in the value space of the type, or fails to refer at all. An <dfn id="dfn-ill-typed">ill-typed</dfn> literal is one whose datatype IRI is <a href="#dfn-recognize" class="internalDFN">recognize</a>d, but whose character string is assigned no value by the <a href="#dfn-lexical-to-value-mapping" class="internalDFN">lexical-to-value mapping</a> for that datatype. </p>
+
+<p> RDF processors are not required to <a href="#dfn-recognize" class="internalDFN">recognize</a> any datatype IRIs other than <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string"><code>rdf:langString</code></a> and <a href="http://www.w3.org/TR/xmlschema11-2/#string"><code>xsd:string</code></a>, but when IRIs listed in <a href="http://www.w3.org/TR/rdf11-concepts/#section-Datatypes">Section 5</a> of [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>] are <a href="#dfn-recognize" class="internalDFN">recognize</a>d, they <em class="rfc2119" title="MUST">MUST</em> be interpreted as described there, and when the IRI <code>rdf:PlainLiteral</code> is <a href="#dfn-recognize" class="internalDFN">recognize</a>d, it <em class="rfc2119" title="MUST">MUST</em> be interpreted to refer to the datatype defined in [<cite><a class="bibref" href="#bib-RDF-PLAIN-LITERAL">RDF-PLAIN-LITERAL</a></cite>]. RDF processors <em class="rfc2119" title="MAY">MAY</em> recognize other datatype IRIs, but when other datatype IRIs are <a href="#dfn-recognize" class="internalDFN">recognize</a>d, the mapping between the datatype IRI and the datatype it refers to <em class="rfc2119" title="MUST">MUST</em> be specified unambiguously, and <em class="rfc2119" title="MUST">MUST</em> be fixed during all RDF transformations or manipulations. In practice, this can be achieved by the IRI linking to an external specification of the datatype which describes both the components of the datatype itself and the fact that the IRI identifies the datatype, thereby fixing a value of the <a href="#dfn-datatype-map" class="internalDFN">datatype map</a> of this IRI.</p>
+
+<p>Literals with <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string"><code>rdf:langString</code></a> as their datatype are an exceptional case which are given a special treatment. The IRI <code>rdf:langString</code> is classified as a datatype IRI, and interpreted to refer to a datatype, even though no L2V mapping is defined for it. The value space of <code>rdf:langString</code> is the set of all pairs of a string with a language tag. The semantics of literals with this as their type are given below. </p>
+
+<p>RDF literal syntax allows any IRI to be used in a typed literal, even when it is not <a href="#dfn-recognize" class="internalDFN">recognize</a>d as referring to a datatype. Literals with such an "unknown" datatype IRI, which is not in the set of <a href="#dfn-recognize" class="internalDFN">recognize</a>d datatypes, <em class="rfc2119" title="SHOULD NOT">SHOULD NOT</em> be treated as errors, although RDF applications <em class="rfc2119" title="MAY">MAY</em> issue a warning. Such literals <em class="rfc2119" title="SHOULD">SHOULD</em> be treated like IRIs and assumed to denote some thing in the universe IR. RDF processors which do not <a href="#dfn-recognize" class="internalDFN">recognize</a> a datatype IRI will not be able to detect some entailments which are visible to one which does. For example, the fact that </p><p><code>ex:a ex:p "20.0000"^^xsd:decimal .</code></p><p>entails </p><p><code>ex:a ex:p "20.0"^^xsd:decimal .</code></p><p>will not be visible to a processor which does not <a href="#dfn-recognize" class="internalDFN">recognize</a> the datatype IRI <code>xsd:decimal</code>.</p>

Thus, any triple, and hence any graph, containing an <a href="#dfn-ill-typed" class="internalDFN">ill-typed</a> literal will be <a href="#dfn-d-unsatisfiable" class="internalDFN">D-unsatisfiable</a>, i.e. false in every D-interpretation.

+<p>A graph is (simply) <dfn id="dfn-d-satisfiable">D-satisfiable</dfn> or <dfn id="dfn-satisfiable-recognizing-d">satisfiable recognizing D</dfn> when it has the value true in some D-interpretation, and a graph S (simply) <dfn id="dfn-d-entails">D-entails</dfn> or <dfn id="dfn-entails-recognizing-d">entails recognizing D</dfn> a graph G when every D-interpretation which satisfies S also D-satisfies G.</p>
+
+<p> Unlike the case with <a href="#dfn-simple-interpretation" class="internalDFN">simple interpretation</a>s, it is possible for a graph to have no satisfying D-interpretations, i.e. to be <dfn id="dfn-d-unsatisfiable">D-unsatisfiable</dfn>.

+<p>Unlike <a title="entail" href="#dfn-entail" class="internalDFN">simple entailment</a>, it is not possible to give a single syntactic criterion to detect all D-entailments, which

+
+<p>In general, any triple containing a literal with a <a href="#dfn-recognize" class="internalDFN">recognize</a>d datatype IRI D-entails another literal when the lexical strings of the literals map to the same value under the lexical-to-value map of the datatype. If two different datatypes in D map lexical strings to a common value, then a triple containing a literal typed with one datatype may D-entail another triple containing a literal typed with a different datatype. For example, <code>"25"^^xsd:integer</code> and <code>"25.0"^^xsd:decimal</code> have the same value, so the above also D-entails </p>

+<p>RDFS does not partition the universe into disjoint categories of classes, properties and individuals. Anything in the universe can be used as a class or as a property, or both, while retaining its status as an individual which may be in classes and have properties. Thus, RDFS permits classes which contain other classes, classes of properties, properties of classes, etc. As the axiomatic triples above illustrate, it also permits classes which contain themselves and properties which apply to themselves. A property of a class is not necessarily a property of its members, nor vice versa. </p>

+<p> The RDF and RDFS entailment patterns listed in the above tables can be viewed as left-to-right rules which add the entailed conclusion to a graph. These rule sets can be used to check RDF (or RDFS) entailment between graphs S and E, by the following sequence of operations:</p>
+<p>1. Add to S all the RDF (or RDF and RDFS) axiomatic triples except those containing the container membership property IRIs <code>rdf:_1, rdf:_2, ...</code>.<br />
+2. For every container membership property IRI which occurs in E, add the RDF (or RDF and RDFS) axiomatic triples which contain that IRI.<br />
+3. Apply the RDF (or RDF and RDFS) inference patterns as rules, adding each conclusion to the graph, to exhaustion; that is, until they generate no new triples. <br />
+4. Determine if E has an instance which is a subset of the set, i.e. whether the enlarged set simply entails E.</p>

+
+<p>The closures are finite. The generation process is decidable and of polynomial complexity. Detecting simple entailment is NP-complete in general, but of low polynomial order when E contains no blank nodes. </p>
+
+<p>Every RDF(S) closure, even starting with the empty graph, will contain all RDF(S) tautologies which can be expressed using the vocabulary of the original graph plus the RDF and RDFS vocabularies. In practice there is little utility in re-deriving these, and a subset of the rules can be used to establish most entailments of practical interest. </p>
+
+<p>If it is important to stay within legal RDF syntax, rule <a href="#dfn-rdfd1" class="internalDFN">rdfD1</a> may be used instead of <a href="#dfn-grdfd1" class="internalDFN">GrdfD1</a>, and the introduced blank node can be used as a substitute for the literal in subsequent derivations. The resulting set of rules will not however be complete.</p>

+<p>To keep the exposition simple, the RDF semantics has been phrased in a way which requires interpretations to be larger than absolutely necessary. For example, all interpretations are required to interpret the whole IRI vocabulary, and the universes of all D-interpretations where D contains
+<code>xsd:string</code> must contain all possible strings and therefore be infinite. This appendix sketches, without proof, how to re-state the semantics using smaller semantic structures, without changing any entailments. </p>
+
+<p>Basically, it is only necessary for an interpretation structure to interpret the <a href="#dfn-name" class="internalDFN">name</a>s actually used in the graphs whose entailment is being considered, and to consider interpretations whose universes are at most as big as the number of names and blank nodes in the graphs. More formally, we can define a <dfn id="dfn-pre-interpretation">pre-interpretation</dfn> over a <a href="#dfn-vocabulary" class="internalDFN">vocabulary</a> V to be a structure I similar to a <a href="#dfn-simple-interpretation" class="internalDFN">simple interpretation</a> but with a mapping only from V to its universe IR. Then when determining whether G entails E, consider only pre-interpretations over the finite vocabulary of <a href="#dfn-name" class="internalDFN">name</a>s actually used in G union E. The universe of such a pre-interpretation can be restricted to the cardinality N+B+1, where N is the size of the vocabulary and B is the number of blank nodes in the graphs. Any such pre-interpretation may be extended to <a href="#dfn-simple-interpretation" class="internalDFN">simple interpretation</a>s, all of which which will give the same truth values for any triples in G or E. Satisfiability, entailment and so on can then be defined with respect to these finite pre-interpretations, and shown to be identical to the ideas defined in the body of the specification.</p>
+
+<p>When considering D-entailment, pre-interpretations may be kept finite by weakening the semantic conditions for datatyped literals so that IR need contain literal values only for literals which actually occur in G or E, and the size of the universe restricted to (N+B)×(D+1), where D is the number of recognized datatypes. (A tighter bound is possible.) For RDF entailment, only the finite part of the RDF vocabulary which includes those container membership properties which actually occur in the graphs need to be interpreted, and the second RDF semantic condition is weakened to apply only to values which are values of literals which actually occur in the vocabulary. For RDFS interpretations, again only that finite part of the infinite container membership property vocabulary which actually occurs in the graphs under consideration needs to be interpreted. In all these cases, a pre-interpretation of the vocabulary of a graph may be extended to a full interpretation of the appropriate type without changing the truth-values of any triples in the graphs.</p>
+
+<p>The whole semantics could be stated in terms of pre-interpretations, yielding the same entailments, and allowing finite RDF graphs to be interpreted in finite structures, if the <em>finite model property</em> is considered important.

Now suppose G entails E, and consider the <a href="http://en.wikipedia.org/wiki/Herbrand_interpretation">Herbrand interpretation</a> I of G defined as follows. IR contains the <a href="#dfn-name" class="internalDFN">name</a>s and blank nodes which occur in the graph, with I(n)=n for each <a href="#dfn-name" class="internalDFN">name</a> n; n is in IP and <a, b> in IEXT(n) just when the triple <a n b> is in the graph. (For IRIs which do not occur in the graph, assign them values in IR at random.)

+<p>The skolemization mapping sk substitutes a unique new IRI for each blank node, so it is 1:1, so has an inverse. Define ks to be the inverse mapping which replaces each skolem IRI by the blank node it replaced. Since sk(G) entails H, a subgraph of sk(G) is an instance of H, say A(H) for some instance mapping A on the blank nodes in H. Then ks(A(H)) is a subgraph of G; and ks(A(H))=A(ks(H)) since the domains of A and ks are disjoint. So ks(H) has an instance which is a subgraph of G, so is entailed by G; and H=sk(ks(H)). QED.</p>

+

+ <p>The intended meaning of this vocabulary is to allow an RDF graph to act as metadata describing other RDF triples. </p>
+
+
+ <p>Consider an example graph containing a single triple:</p>
+
+ <p><code>ex:a ex:b ex:c .</code></p>
+
+ <p>and suppose that IRI <code>ex:graph1</code> is used to <a href="#dfn-identify" class="internalDFN">identify</a> this graph. Exactly how this identification is achieved is external to the RDF model, but it might be by the IRI resolving to a concrete syntax document describing the graph, or by the IRI being the associated name of a named graph in a dataset. Assuming that the IRI can be used to refer to the triple, then the reification vocabulary allows us to describe the first graph in another graph:</p>
+
+ <p><code>ex:graph1 rdf:type rdf:Statement .<br />
+ ex:graph1 rdf:subject ex:a .<br />
+ ex:graph1 rdf:predicate ex:b .<br />
+ ex:graph1 rdf:object ex:c .</code></p>
+
+ <p>The second graph is called a <dfn id="dfn-reification">reification</dfn> of the triple in the first
+ graph.</p>
+<p> Reification is not a form of quotation. Rather, the reification describes the
+ relationship between a token of a triple and the resources that the triple refers
+ to. The value of the <code>rdf:subject</code> property is not the
+ subject IRI itself but the thing it denotes, and similarly for <code>rdf:predicate</code> and <code>rdf:object</code>. For example, if the referent of <code>ex:a</code> is Mount Everest, then the subject of the reified triple is also the mountain, not the IRI which refers to it.
+
+</p>
+
+<p><a href="#dfn-reification" class="internalDFN">Reification</a>s can be written with a blank node as subject, or with an IRI subject which does not <a href="#dfn-identify" class="internalDFN">identify</a> any concrete realization of a triple, in both of which cases they simply assert the existence of the described triple. </p>
+
+ <p>The subject of a <a href="#dfn-reification" class="internalDFN">reification</a> is intended to refer to a concrete realization of an RDF triple, such as a document in a surface syntax, rather than a triple considered as an abstract object. This supports use cases where properties such as dates of
+ composition or provenance information are applied to the
+ reified triple, which are meaningful only when thought of as
+ referring to a particular instance or token of a triple. </p>
+
+ <p>A <a href="#dfn-reification" class="internalDFN">reification</a> of a triple does not entail the triple, and is not
+ entailed by it. The
+ <a href="#dfn-reification" class="internalDFN">reification</a> only says that the triple token exists and what it is about,
+ not that it is true, so it does not entail the triple. On the other hand, asserting a triple does not automatically imply that any
+ triple tokens exist in the universe being described by the triple.
+ For example, the triple might be part of an ontology describing
+ animals, which could be satisfied by an interpretation in which the
+ universe contained only animals, and in which a <a href="#dfn-reification" class="internalDFN">reification</a> of it was therefore
+ false.</p>
+
+ <p>Since the relation between triples and <a href="#dfn-reification" class="internalDFN">reification</a>s of triples
+ in any RDF graph or graphs need not be one-to-one, asserting a
+ property about some entity described by a <a href="#dfn-reification" class="internalDFN">reification</a> need not
+ entail that the same property holds of another such entity, even if
+ it has the same components. For example,</p>

+ <p>RDF provides vocabularies for describing three classes of
+ containers. Containers have a type, and their members can
+ be enumerated by using a fixed set of <em>container membership
+ properties</em>. These properties are indexed by integers to
+ provide a way to distinguish the members from each other, but these
+ indices should not necessarily be thought of as defining an
+ ordering of the container itself; some containers are considered to be unordered.</p>
+
+ <p>The <a href="#dfn-rdfs-vocabulary" class="internalDFN">RDFS vocabulary</a> adds a generic membership
+ property which holds regardless of position, and classes containing
+ all the containers and all the membership properties.</p>
+
+ <p>One should understand this vocabulary as <em>describing</em>
+ containers, rather than as a tool for constructing them, as
+ would typically be supplied by a programming language. The actual containers are entities in the semantic universe,
+ and RDF graphs which use the vocabulary simply provide very basic
+ information about these entities, enabling an RDF graph to
+ characterize the container type and give partial information about
+ the members of a container. Since the RDF container vocabulary is
+ so limited, many 'natural' assumptions concerning RDF containers
+ cannot be formally sanctioned by the RDF formal semantics. This should not be taken as
+ meaning that these assumptions are false, but only that RDF does
+ not formally entail that they must be true.</p>
+
+ <p>There are no special semantic conditions on the container
+ vocabulary: the only 'structure' which RDF presumes its containers
+ to have is what can be inferred from the use of this vocabulary and
+ the general RDF semantic conditions. This amounts to knowing the type of a container, and having a partial
+ enumeration
+ of the items in the container. The intended mode of use is that things
+ of type <code>rdf:Bag</code>
+ are considered to be unordered but to allow duplicates; things of
+ type <code>rdf:Seq</code> are considered to be ordered, and things
+ of type <code>rdf:Alt</code> are considered to represent a
+ collection of alternatives, possibly with a preference ordering.
+ If the container is of an ordered type, then the ordering of items in the container is intended to be
+ indicated by the numerical ordering of the container membership
+ properties, which are assumed to be single-valued.
+ However, these informal conditions are not reflected in any formal RDF
+ entailments.</p>
+
+
+<p>The RDF semantics does not support any entailments which could arise from enumerating
+ the elements of an unordered <code>rdf:Bag</code> in a different order. For example,</p>
+
+ <p><code>_:xxx rdf:type rdf:Bag .<br />
+ _:xxx rdf:_1 ex:a .<br />
+ _:xxx rdf:_2 ex:b .</code></p>
+
+ <p>does not entail</p>
+
+ <p><code>_:xxx rdf:_1 ex:b .<br />
+ _:xxx rdf:_2 ex:a .</code></p>
+
+ <p>(If this conclusion were <a href="#dfn-valid" class="internalDFN">valid</a>, then the result of
+ adding it to the original graph would be <a href="#dfn-entail" class="internalDFN">entail</a>ed by the graph, and this would assert that both elements were in both
+ positions. This is a consequence of the fact that RDF is a purely
+ assertional language.)</p>
+
+ <p>There is no assumption that a property of a container applies to
+ any of the elements of the container, or vice versa. </p>
+ <p>There is no formal requirement that
+ the three container classes are disjoint, so that for example
+ it is consistent to assert that something is both an <code>rdf:Bag</code> and an <code>rdf:Seq</code>.
+ There is no assumption that containers are gap-free, so that for example</p>
+ <p><code>_:xxx rdf:type rdf:Seq.<br />
+ _:xxx rdf:_1 ex:a .<br />
+ _:xxx rdf:_3 ex:c .</code></p>
+
+ <p>does not entail</p>
+
+ <p><code>_:xxx rdf:_2 _:yyy .</code></p>
+
+ <p>There is no way in RDF to assert
+ that a container contains only a fixed number of members. This is a
+ reflection of the fact that it is always consistent to add a triple
+ to a graph asserting a membership property of any container. And
+ finally, there is no built-in assumption that an RDF container has

+ <p>RDF provides a vocabulary for describing collections, i.e.'list
+ structures', in terms of head-tail links. Collections differ from
+ containers in allowing branching structure and in having an
+ explicit terminator, allowing applications to determine the exact
+ set of items in the collection.</p>
+
+
+<p>As with containers, no special semantic conditions are imposed on this vocabulary
+ other than the type of <code>rdf:nil</code> being <code>rdf:List</code>. It
+ is intended for use typically in a context where a container is described using
+ blank nodes to connect a 'well-formed' sequence of items, each described by
+ two triples of the form
+<code><br />
+ <br />
+ _:c1 rdf:first aaa .<br />
+ _:c1 rdf:rest _:c2 .</code></p>
+
+
+<p>where the final item is indicated by the use of <code>rdf:nil</code> as the
+ value of the property <code>rdf:rest</code>. In a familiar convention, <code>rdf:nil</code>
+ can be thought of as the empty collection. Any such graph amounts to an assertion
+ that the collection exists, and since the members of the collection can be determined
+ by inspection, this is often sufficient to enable applications to determine
+ what is meant. The semantics does not require any collections
+ to exist other than those mentioned explicitly in a graph (and the empty collection).
+ For example, the existence of a collection containing two items does not automatically
+ guarantee that the similar collection with the items permuted also exists:
+<code>
+<br /><br />
+ _:c1 rdf:first ex:aaa .<br />
+ _:c1 rdf:rest _:c2 .<br />
+ _:c2 rdf:first ex:bbb .<br />
+ _:c2 rdf:rest rdf:nil . </code></p>

+ _:c3 rdf:rest _:c4 .<br />
+ <span>_:c4 rdf:first</span> ex:aaa .<br />
+ _:c4 rdf:rest rdf:nil .
+ </code></p>
+
+ <p>Also, RDF imposes no 'well-formedness' conditions on the use of this
+ vocabulary, so that it is possible to write RDF graphs which assert
+ the existence of highly peculiar objects such as lists with forked
+ or non-list tails, or multiple heads:</p>
+
+<p><code>_:666 rdf:first ex:aaa .<br />
+ _:666 rdf:first ex:bbb .<br />
+ _:666 rdf:rest ex:ccc .<br />
+ _:666 rdf:rest rdf:nil . </code></p>
+
+
+<p>It is also possible to write a set of triples which under-specify a collection
+ by failing to specify its <code>rdf:rest</code> property value.</p>
+
+
+<p><a href="#dfn-semantic-extension" class="internalDFN">Semantic extension</a>s may
+ place extra syntactic well-formedness restrictions on the use of this vocabulary
+ in order to rule out such graphs. They may
+ exclude interpretations of the collection vocabulary which violate the convention
+ that the subject of a 'linked' collection of two-triple items of the form described
+ above, ending with an item ending with <code>rdf:nil</code>, denotes a totally
+ ordered sequence whose members are the denotations of the <code>rdf:first</code>
+ values of the items, in the order got by tracing the <code>rdf:rest</code> properties
+ from the subject to <code>rdf:nil</code>. This permits sequences which contain
+ other sequences.</p>

+
+<p>The basic idea of using an explicit extension mapping to allow self-application without violating the axiom of foundation was
+suggested by Christopher Menzel. The generalized RDF syntax used in Appendix A, and the example showing the need for it, were suggested by Herman ter Horst, who also proved completeness and complexity results for the rule sets. Jeremy Carroll first showed that simple entailment is NP-complete in general. Antoine Zimmerman suggested several simplifications and improvements to the proofs and presentation.</p>

+<p>The RDF 1.1 editors acknowledge valuable contributions from Thomas Baker, Dan Brickley, Gavin Carothers, Jeremy Carroll, Pierre-Antoine Champin, Richard Cyganiak, Martin J. Dürst, Alex Hall, Steve Harris, Ivan Herman, Eric Prud'hommeaux, Andy Seaborne, David Wood and Antoine Zimmermann. </p>
+<p>This specification is a product of extended deliberations by <a href="http://www.w3.org/2000/09/dbwg/details?group=46168&public=1">members of the RDF Working Group</a>. This specification draws upon the earlier specification [<cite><a class="bibref" href="#bib-RDF-MT">RDF-MT</a></cite>], whose editor acknowledged valuable inputs from Jeremy Carroll, Dan Connolly, Jan Grant, R. V. Guha, Herman ter Horst, Graham Klyne, Ora Lassilla, Brian McBride, Sergey Melnick, Peter Patel-Schneider, Jos deRoo and Patrick Stickler.

-<p>RDF properties may be thought of as attributes of resources and inthis sense correspond to traditional attribute-value pairs. RDF
-properties also represent relationships between resources.</p>
-<p>RDF however, provides no mechanisms for describing these properties, nordoes it provide any mechanisms for describing the relationships between these
-properties and other resources. That is the role of the RDF vocabularydescription language, RDF Schema. RDF Schema defines classes and properties
-that may be used to describe classes, properties and other resources.</p>
-<p>This document does not specify a vocabulary of descriptive properties suchas "author". Instead it specifies mechanisms that may be used to name and
-describe properties and the classes of resource they describe.</p>-->
-
- <p>
- RDF Schema is a <a href="http://www.w3.org/TR/rdf11-mt/#semantic-extensions-and-entailment-regimes">semantic
- extension</a> of RDF. It provides mechanisms for describing groups of
- related resources and the relationships between these resources. RDF
- Schema is written in RDF
- using the terms described in this document. These resources are used to
- determine characteristics of other resources, such as the <a href="#ch_domain">domains</a>
- and <a href="#ch_range">ranges</a> of properties.
- </p>
- <p>The RDF Schema class and property system is similar to the type
- systems of object-oriented programming languages such as Java. RDF
- Schema differs from many such systems in that instead of defining a
- class in
- terms of the properties its instances may have, RDF Schema
- describes properties in terms of the classes of
- resource to which they apply. This is the role of the <a href="#ch_domain">domain</a>
- and <a href="#ch_range">range</a>
- mechanisms described in this specification. For example, we could
- define the <code>eg:author</code> property to have a domain of <code>eg:Document</code>
- and a range of
- <code>eg:Person</code>, whereas a classical object oriented system might
- typically define a class <code>eg:Book</code> with an attribute called
- <code>eg:author</code> of type <code>eg:Person</code>. Using the RDF
- approach, it is easy for others to subsequently define additional
- properties with a domain of eg:<code>Document</code> or a range of
- <code>eg:Person</code>. This can be done without the need to re-define
- the original description of
- these classes. One benefit of the RDF property-centric approach is that
- it
- allows anyone to extend the description of existing resources, one of
- the
- architectural principles of the Web [<cite><a class="bibref" href="#bib-BERNERS-LEE98">BERNERS-LEE98</a></cite>].</p>
- <p>This specification does not attempt to enumerate all the possible forms
- of
- representing the meaning of RDF
- classes and properties. Instead, the RDF Schema strategy is
- to acknowledge that there are many techniques through which the meaning
- of
- classes and properties can be described. Richer vocabulary or 'ontology'
- languages such as OWL [<cite><a class="bibref" href="#bib-OWL2-OVERVIEW">OWL2-OVERVIEW</a></cite>], inference rule
- languages and other formalisms (for example temporal logics) will each
- contribute to our ability to capture meaningful generalizations about
- data in
- the Web.

-RDF vocabulary designers can create and deploy Semantic Webapplications using the RDF Schema facilities,
-while exploring richer languages that share thisgeneral approach.
--->
-</p>
- <p>The language defined in this specification consists of a collection of
- RDF resources that can be used to describe other RDF resources in
- application-specific RDF vocabularies. The core vocabulary is defined in
- a namespace informally called <code>rdfs</code> here. That namespace is
- identified by the IRI</p>
- <blockquote>
- <code>http://www.w3.org/2000/01/rdf-schema#</code>
- </blockquote>
- and is conventionally associated with the prefix <code>rdfs:</code>. This
- specification also uses the prefix
- <code>rdf:</code> to refer to the RDF namespace
- <p></p>
- <blockquote>
- <code>http://www.w3.org/1999/02/22-rdf-syntax-ns#</code>
- </blockquote>
- <p>For convenience and readability, this specification uses an abbreviated
- form to represent IRIs. A name of the form prefix:suffix should be
- interpreted as a IRI consisting of the IRI associated
- with the prefix concatenated with the suffix.</p>

- the set of the instances of the class. Two classes may have the same set

- once. Unlike containment in the physical world, a container may be
- contained in itself.</p>
- <p>Three different kinds of container are defined. Whilst the formal
- semantics [<cite><a class="bibref" href="#bib-RDF11-MT">RDF11-MT</a></cite>] of all three classes of container are
- identical,
- different classes may be used to indicate informally further
- information. An rdf:Bag is used to indicate that the container is
- intended to be unordered. An rdf:Seq is used to indicate that the
- order indicated by the numerical order of the <a href="#ch_containermembershipproperty">container
- membership properties</a>
- of the container is intended to be significant. An rdf:Alt container
- is used
- to indicate that typical processing of the container will be to select
- one of
- the members.</p>
- <p>Just as a hen house may have the property that it is made of wood,
- that
- does not mean that all the hens it contains are made of wood, a
- property of a
- container is not necessarily a property of all of its members.</p>
- <p>RDF containers are defined by the following classes and properties.</p>

- <p>The RDF Schema design was originally produced by the RDF Schema Working
- Group (1997-2000). The current specification is largely an editorial
- clarification of that design, and has benefited greatly from the hard
- work of
- the <a href="http://www.w3.org/2001/sw/RDFCore/">RDF Core Working Group</a>
- <a href="http://www.w3.org/2001/sw/RDFCore/#Membership">members</a>, and
- from
- implementation feedback from many members of the <a href="http://www.w3.org/RDF/Interest/">RDF
- Interest Group</a>. In
- 2013-2014 Guus Schreiber edited this document on behalf of the <a href="http://www.w3.org/2011/rdf-wg/">RDF
- Working Group</a>
- to bring it in line with the RDF 1.1 specifications. </p>
- <p>David Singer of IBM was the chair of the original RDF Schema group
- throughout most of the development of this specification; we thank David
- for
- his efforts and thank IBM for supporting him and us in this endeavor.
- Particular thanks are also due to Andrew Layman for his editorial work
- on
- early versions of this specification.</p>

- <ul>
- <li>Conversion to ResPec, inclduing formatting of examples and notes.</li>
- <li>Refereces and anchors to RDF 1.0 documents where appropriate
- replaced by references and anchors to RDF 1.1 documents.</li>
- <li>Replaced the term "URI Reference" with the term "IRI". </li>
- <li>Removed discussion about distinction between plain and typed
- literals, as this distinction is absent in RDF 1.1 and has no
- technical bearing on RDF Schema.</li>
- <li>Fixed incorrect pointer to RDF Primer example 16 to example 21.</li>
- <li>Removed the introductory paragraph of Sec. <a href="#ch_reificationvocab">"Reification
- Vocabulary"</a>, as this discussion is not related to the
- technical content and is irrelevant and confusing now. </li>
- <li>Update of affiliation of the editors. </li>
- <li>Added RDF WG to the Acknowledgements section.</li>
- <li>Renamed the document from "RDF Vocabulary Description Language
- 1.0: RDF Schema" to "RDF Schema 1.1", as the term Vocabulary
- Description Language has led to confusion.</li>
- <li>Three paragraphs of the Introduction were left out. These
- paragraphs described the things that RDF Schema does not do and are
- now much less relevant than in 2004. </li>
- <li>Added the datatypes <code>rdf:langString</code> and <code>rdf:HTML</code>.
- </li>
- <li>Removed Appendix "RDF Schema in RDF/XML". It was informative, but
- now out of date, in terms of content and in terms of
- syntax.</li>
- <li>Marked <code>rdf:HTML</code> and <code>rdf:XMLLiteral</code>
- as non-normative.</li>
- <li>Removed references to 2004 Primer from Secs. 5.1, 5.2
- and 5.4.3. In the latter case the example referred to was
- moved into this document for readability purposes. </li>

- <p>The following is an outline of the main changes made to the 2004
- specification, latest first, since the Last Call Working Draft of <a href="http://www.w3.org/TR/2003/WD-rdf-schema-20030123/">23 January
- 2003</a>. See the <a href="http://www.w3.org/2001/sw/RDFCore/20030123-issues/#schema">Last
- Call issue tracking document</a> for details of the specific issues
- raised regarding this specification.
- </p>
- <ul>
- <li>Amended Appendix A to note that the RDF/XML description of RDF and
- RDFS terms is not directly published at the RDFS namespace, but
- split between the 'rdf:' and 'rdfs:' namespace documents. Also
- removed the pre-REC warning that the WG might choose to change the
- namespace URI prior to Recommendation.</li>
- <li>Amended rdfs:range specification for rdf:predicate for consistency
- with the Semantics document (previously rdf:Property; now,
- rdfs:Resource)</li>
- <li>Removed reference to RDF mimetypes doc, as the IETF draft has
- expired and is 404 missing on their site.</li>
- <li>Reification vocabulary redescribed (<a href="http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Aug/0161.html">details</a>).</li>
- <li>Reworded rdfs:comment for rdfs:member, changing "container" to
- "resource"</li>
- <li>Reworded lead-in to Appendix A per <a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003JulSep/0170.html">0170.html</a>.
- </li>
- <li>OWL references now go to OWL specs rather than WebOnt homepage.
- Fixed minor typos per <a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0373.html">0373.html</a>)</li>
- <li>Reworded rdf:nil to tone down the imperative style.</li>
- <li>Added note to Properties section warning about over-use of
- sub-property,
- and referencing OWL, an editorial suggestion from Bijan Parsia. (<a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003AprJun/0177.html">details</a>).
- </li>
- <li>Regarding <a href="http://www.w3.org/2001/sw/RDFCore/20030123-issues/#pfps-12">pfps-12</a>,
- <a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003AprJun/0277.html">discussion</a>
- led to rdf:first/rest/List/nil rewritten per Peter Patel-Schneider's
- suggestion.</li>
- <li>Change to description of subProperty and subClass, to match <a href="http://www.w3.org/TR/2004/REC-rdf-mt-20040210/#change">changes
- to RDF Semantics</a>. See
- <a href="http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Jul/0161.html">discussion</a>

- <li>Edits <a href="http://lists.w3.org/Archives/Public/www-rdf-comments/2003AprJun/0099.html">closing</a>
- 'what is rdf schema' issue by clarifying that RDFS is a semantic

-similar
-to
-the

-of

-such

-RDF
-differs
-from
-many
-such

-in
-that
-instead
-of
-defining
-a
-class
-in
-terms
-of
-the

-its

-the
-RDF
-vocabulary
-description
-language
-describes
-properties
-in
-terms
-of
-the

-of
-resource
-to
-which
-they
-apply.

-is
-the
-role
-of

-domain
-</a>
-and
-<a href="#ch_range">
-range
-</a>
-mechanisms
-described
-in

-For
-example,
-we
-could
-define
-the
-<code>
-eg:author
-</code>
-property
-to
-have
-a
-domain
-of
-<code>
-eg:Document
-</code>
-and
-a
-range
-of
-<code>
-eg:Person
-</code>,
-whereas
-a
-classical
-object
-oriented
-system
-might
-typically
-define
-a
-class
-<code>
-eg:Book
-</code>
-with
-an
-attribute
-called
-<code>
-eg:author
-</code>
-of
-type
-<code>
-eg:Person
-</code>.
-Using
-the
-RDF
-approach,
-it
-is
-easy
-for

-to
-subsequently
-define
-additional

-a

-of

-<code>

-or
-a

-of
-<code>

-This
-can
-be
-done
-without
-the
-need
-to
-re-define
-the
-original
-description
-of
-these
-classes.
-One
-benefit
-of
-the
-RDF
-property-centric
-approach
-is
-that
-it
-allows
-anyone
-to

-The

-Classes

-<p>
-RDF

-Two
-classes
-may

-For

-may
-define
-the

-of
-people
-living
-at
-the
-same
-address
-as
-the

-The

-Office
-may
-define
-the
-class
-of
-people
-whose
-address
-has
-the
-same
-zip
-code
-as
-the
-address
-of
-the
-author.
-It
-is
-possible
-for
-these
-classes
-to
-have
-exactly
-the
-same
-instances,
-yet
-to
-have
-different
-properties.
-Only
-one
-of
-the
-classes
-has
-the

-was

-<p>
-A
