+
+ <p>This document is informative in nature. Its
+ purpose is to provide a summary of differences between RDF versions 1.0
+ and 1.1 and to introduce new additions in a very brief manner.
+ </p>
+
+ <p>Readers new to RDF should start with the RDF 1.1 Primer
+ [<cite><a class="bibref" href="#bib-RDF11-PRIMER">RDF11-PRIMER</a></cite>] and then move on to the specifications in which they are
+ most interested. This document is meant to serve as a guide for those
+ already familiar with RDF 1.0 who wish to understand changes in version
+ 1.1.</p>
+
+ <p>Normative specifications of RDF can be found in the
+ following documents: </p>
+ <ul>
+ <li>A document describing the basic concepts underlying RDF, as
+ well as abstract syntax ("RDF Concepts and Abstract Syntax")
+ [<cite><a class="bibref" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>]</li>
+ <li>A document describing the formal model-theoretic semantics
+ of RDF ("RDF Semantics") [<cite><a class="bibref" href="#bib-RDF11-MT">RDF11-MT</a></cite>]</li>
+ <li>Specifications of 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>], N-Triples [<cite><a class="bibref" href="#bib-N-TRIPLES">N-TRIPLES</a></cite>],
+ N-Quads [<cite><a class="bibref" href="#bib-N-QUADS">N-QUADS</a></cite>] and JSON-LD [<cite><a class="bibref" href="#bib-JSON-LD">JSON-LD</a></cite>]. RDFa [<cite><a class="bibref" href="#bib-RDFA-PRIMER">RDFA-PRIMER</a></cite>]
+ is also a concrete syntax for RDF, but it was not defined
+ by the RDF Working Group.</li>
+ <li>An RDF Vocabulary Description Language, RDF Schema
+ [<cite><a class="bibref" href="#bib-RDF-SCHEMA">RDF-SCHEMA</a></cite>]</li>

+
+ <p>Most of the changes between RDF and RDF 1.1 do not have any effect on

+
+ <p>Datatype entailment formally refers to a set of 'recognized' datatype IRIs.
+ The RDF 1.0 Semantics used the concept of a datatype map: in the new semantic
+ description, this is the mapping from recognized IRIs to the datatypes they
+ identify. This change does not have any effect on implementation or semantic
+ entailments.</p>
+
+ <p>RDF entailment has two required datatypes <code>xsd:string</code> and <code>rdf:langString</code>
+ which must be recognized, but this doesn't appreciably add to RDF
+ entailment as these two datatypes replace plain literals.</p>
+
+ <p>One change that does affect entailment is that graphs containing invalid
+ literals (e.g., <code>"a"^^xsd:integer</code>) are immediately inconsistent for
+ recognized datatypes, even in sub-RDFS entailment regimes.</p>
+
+ <p>RDF 1.1 includes RDF Datasets. However, the semantics of RDF Datasets in
+ RDF 1.1 is minimal and entailment per se is only defined on RDF graphs so
+ there are no changes here.</p>

-
-<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>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>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

-appropriate values, and a reasoning application might use it to infer

-
-<p>RDF vocabularies can describe relationships between vocabulary items from

-to RDF containers with examples may be found in the <a href="http://www.w3.org/TR/2004/REC-rdf-primer-20040210/#containers">RDF
-2004 Primer</a>. The same resource may appear in a container more than

-
-<p>Three different kinds of container are defined. Whilst the formal

-different classes may be used to indicate informally further

-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 member ship 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
