To: public-owl-wg@w3.org

I effected the proposal for ISSUE-29 as far as Syntax, Semantics, and
Mapping are concerned.  As usual changes can be found in the notes on
the issue.  The only substantive changes are in Mapping.

Subject: a proposal for owl:Datarange (and datatype facets) (ISSUE-29, ISSUE-74)
Date: Mon, 07 Jan 2008 04:26:27 -0500 (EST)

> Here is a proposal for how to proceed on issues 29 and 74.  
> 1. OWL datatypes are RDF datatypes, as in
>    http://www.w3.org/TR/rdf-mt/#dtype_interp and
>    http://www.w3.org/TR/rdf-concepts/#section-Datatypes, and thus not
>    necessarily XML Schema 1.0 datatypes (but it may be that RDF
>    datatypes conform with XML Schema 1.1 datatypes).
> 2. OWL also has complex data ranges, e.g., data one-of, data complement,
>    and facet-restricted data ranges, which are not necessarily RDF
>    datatypes (because they need not have a URI).
> 3. In OWL Full
>    a) complex data ranges (and datatypes) are instances of rdf:Datatype,
>       which is OK because not all instances of rdf:Datatype need be RDF
>       datatypes (from RDF Semantics
>       http://www.w3.org/TR/rdf-mt/#dtype_interp); 
>       and 


> 4. In OWL Full, owl:Datarange is deprecated (and made equivalent to
>    rdfs:Datatype).

The equivalence has to be put in the to-be-developed OWL Full semantics.
