RDF Datatyping PART 1 [was: Agenda for RDFCore WG Telecon 2002-08-30]

[trying to catch up w.r.t.
RDF Datatyping -- Current Working Proposal
Last Modified: 29 August 2002]
-- http://www-nrc.nokia.com/sw/rdf-datatyping.html

> PART 1: Core Proposal
> 2.1 rdfs:Datatype

so I guess we have

===========================================================
rdfs:Datatype rdf:type rdfs:Class .
rdfs:Datatype rdfs:subClassOf rdf:Property .
===========================================================

IF                                    | THEN
-----------------------------------------------------------
?d rdf:type rdfs:Datatype .           | ?d rdfs:domain ?d .


> 2.3 Typed Literal

I still have to try have running code where that first item
of that pair is "a URI Reference denoting a datatype"
I was/am quite believing that an abbreviated token would
be enough to support XML-Schema primitive datatypes
(and an unquoted numeral for integer numbers
like DanC's :jenny :age 10.
in http://www.w3.org/2000/10/swap/test/dt/typedLit.n3)


> 4. RDF Datatyping Model Theory

I would add here the imposed semantic conditions like

===========================================================
rdfs:Datatype rdf:type rdfs:Class .
rdfs:Datatype rdfs:subClassOf rdf:Property .
===========================================================

and the closure rules like

IF                                    | THEN
-----------------------------------------------------------
?d rdf:type rdfs:Datatype .           | ?d rdfs:domain ?d .

[I wonder if there are other closure rules...]
