-    
-      <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
-        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>

-<h2 aria-level="1" role="heading" id="h2_ch_classes"><span class="secno">2. </span>Classes</h2>
-      <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.
-        The term super-class is used as the inverse of subclass. If a class C'
-        is a super-class of a class C, then all instances of C are also
-        instances of C'.
-      </p>
-      <p>The RDF Concepts and Abstract Syntax [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>] specification
-        defines the RDF concept of an <a href="http://www.w3.org/TR/rdf11-concepts/#section-Datatypes">RDF
-          datatype</a>. All datatypes are classes. The instances of a class that

-      <p>This specification introduces an RDF vocabulary for describing the
-        meaningful use of properties and classes in RDF data. For example, an
-        RDF
-        vocabulary might describe limitations on the types of values that are
-        appropriate for some property, or on the classes to which it makes sense
-        to
-        ascribe such properties.</p>
-      <p>RDF Schema provides a mechanism for describing this information, but
-        does not say whether or how an application should use it. For example,
-        while an RDF vocabulary can assert that an <code>author</code> property
-        is used to
-        indicate resources that are instances of the class <code>Person</code>,
-        it
-        does not say whether or how an application should act in processing that
-        range information. Different applications will use this information in
-        different ways. For example, data checking tools might use this to help
-        discover errors in some data set, an interactive editor might suggest
-        appropriate values, and a reasoning application might use it to infer
-        additional information from instance data.</p>
-      <p>RDF vocabularies can describe relationships between vocabulary items
-        from
-        multiple independently developed vocabularies. Since IRIs are used
-        to identify classes and properties on the Web, it is possible to create
-        new
-        properties that have a <code>domain</code> or <code>range</code> whose

-        <ul>

-          <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 &quot;URI Reference&quot; with the term &quot;IRI&quot;. </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">&quot;Reification
-              Vocabulary&quot;</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 &quot;RDF Vocabulary Description Language
-            1.0: RDF Schema&quot; to &quot;RDF Schema 1.1&quot;, 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 &quot;RDF Schema in RDF/XML&quot;. 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>

-          <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>

-          </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>).

-An RDFS description of the <a href="http://www.w3.org/TR/rdf11-mt/#rdf-interpretations">RDF vocabulary</a> and <a href="http://www.w3.org/TR/rdf11-mt/#rdfs-interpretations">RDFS vocabulary</a> is given here in RDF/XML syntax. 
-It includes statements describing RDF resources originally introduced bythe 1999 RDF Model and Syntax specification [[RDFMS]], as well as definitions for
-resources introduced in the RDF Schema vocabulary.</p>
-<p>This material is also available as <a href="rdfs-namespace">a separate
-RDF/XML document</a>. It does not necessarily match the contentpublished at the <a

-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
