<ul><li><p class="changenote"> In the 2004 RDF 1.0 specification, datatype D-entailment was defined as a semantic extension 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>RDF literals and datatypes are fully described in [[!RDF-CONCEPTS]]. In summary: RDF literals are either language-tagged strings, or datatyped literals which
combine a string and an IRI identifying a datatype. A datatype is understood to define a partial mapping, called the <dfn>lexical-to-value mapping</dfn>, from character strings to values, and the literal refers to the value obtained by applying this mapping to the character string. If the mapping gives no value for the literal string, then the literal has no referent. The <dfn>value space</dfn> of a datatype is the range of the <a>lexical-to-value mapping</a>. Every literal with that type either refers to a value in the value space, or fails to refer at all. An <dfn>ill-typed</dfn> literal is one whose datatype IRI is recognized, but whose character string is not in the domain of the datatype lexical-to-value mapping. Datatypes are indicated by IRIs.
