RDF Core have just published a number of specs. Do take a
look (details fwd'd below).
It's good to see RDF Schema moving again. It is largely an
editorial clarification and slight technical simplification of the
spec you know and love. This version does include the beginnings
of a worked example, replacing some of the rather abstract
figures in the last spec with a more practical usage scenario.
Comments, feedback and suggestions on that would be particularly
appreciated (by me at least!).
I'd like to expand on this example, ie.
in the next version. The current example shows the declaration of
a property 'eg:author' with a range of 'eg:Person' and a
domain of 'eg:Document', noting that
An extension of this example might show a subproperty relationship between
eg:author and the better known and more general Dublin Core ([DCMI])
The RDF spec family now includes a Test Cases doc. It would be
good to work up a full test case based on this scenario,
showing the creation of specialized sub-properties of DC
I'm off to WWW2002 now so may be out of email contact for a
bit, but will try to catch up with any followups from the conference.

We are pleased to announce the following recently published Working Drafts
from the RDFCore Working Group.
The following documents published in the past couple days:
RDF Model Theory
RDF Vocabulary Description Language 1.0: RDF Schema
RDF Test Cases
accompanied with the recently published 2002-03-25
RDF/XML Syntax Specification (Revised)
constitute the primary deliverables of the RDF Core Working Group.
The RDF Primer provides an account of the fundamentals required to use RDF
in applications. The RDF/XML Syntax Specification document updates the
grammar in the Resource Description Framework (RDF) Model and Syntax
Specification in terms of the XML Infoset and RDF Model Theory. RDF Model
Theory Working Draft specifies model-theoretic semantics for RDF and RDF
Schema. RDF Schema is a revision of the RDF Schema Candidate
Recommendation of March 27 2000, defines a basic vocabulary which enable
communities to declare and relate RDF vocabularies. RDF Test Cases provide
a documented set of examples that correspond to technical issues the
Working Group is addressing.
Comments on these documents, should be sent to [log in to unmask]
This is the preferred method of providing feedback. Implementors are
particularly encouraged to supply the results of running their tool-kits
against the test cases. Public comments and their responses can be accessed at
