To: W3C RDF WG <public-rdf-wg@w3.org>
This is a proposal to modify the wording of Concepts and Semantics to finish the work needed for issue-118 in the core documents. The intent is to eliminate the idea of a "datatype map" and talk only about datatype IRIs and how they are interpreted.

Concepts:

1.3  The Referent of an IRI

The resource denoted by an IRI is also called its referent. For some IRIs with particular meanings, such as those identifying XSD datatypes, the referent is fixed by this specification. For all other IRIs, what exactly is denoted by any given IRI is not defined by this specification.


5.4 Datatype IRIs

Datatypes are identified by IRIs. If D is a set of IRIs which are used to refer to datatypes, then the elements of D are called <em>recognized</em> datatype IRIs. All semantic interpretations must conform to a fixed mapping between recognized IRIs and the datatypes they identify. All interpretations I [[must]] recognize the following IRIs with the mappings specified:

I(http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral) is the datatype rdf:XMLLiteral ;
I(http://www.w3.org/1999/02/22-rdf-syntax-ns#HTM) is the datatype rdf:HTML ;
I(http://www.w3.org/2001/XMLSchema#xxx) is the RDF-compatible XSD type named xsd:xxx, for every XSD type listed in section 5.1

Semantic extensions of RDF [[may]] recognize other datatype IRIs and impose fixed interpretations upon them, but they [[must not]] interpret a datatype IRI differently from its defining specification.

------------

There is one issue which remains not fully worked out, which I will address in a separate email.
