+
+    <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 (&quot;RDF Concepts and Abstract Syntax&quot;)

+      of RDF (&quot;RDF Semantics&quot;) [<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>],

+			is also a concrete syntax for RDF, but it was not defined
+			by the RDF Working Group.</li>

+				Group decided to follow the changes to the DOM in order to support the new datatype <code>rdf:HTML</code>.
+				The unfinished status of DOM version 4 is why both <code>rdf:HTML</code> and <code>rdf:XMLLiteral</code> are non-normative
+				in RDF 1.1 Concepts.  RDF 1.1 Concepts and Abstract Syntax clarifies functionality deemed to be
+				useful for those including fragments of XML and HTML content in RDF serialization formats.</p>

+
+		<p>Most of the changes between RDF and RDF 1.1 do not have any effect on
+			implementations of entailment.</p>
+
+		<p>Datatype entailment formally refers to a set of 'recognized' datatypes,
+			replacing datatype maps in RDF 1.0 Semantics, but this does not have any
+			effect on implementation.</p>
+		
+		<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>&quot;a&quot;^^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>
