Re: Refactoring RDF/XML Syntax W3C Working Draft

Would be interested to know if anyone can say what impact the refactored
RDF/XML syntax proposal will have on our application of RDF? We are using
public identifiers (the DOI) to manage multiple resources and have an RDF
Schema which describes a resource hierarchy whose principle semantics are
structural (grouping, ordering, hierarchy). The bulk of the proposed
refactoring seems to address the RDF container productions.

Thanks,
Tony


1. Synopsis: The DObject Model describes how a DOI is used to manage
multiple resources. In the DObject Model a core set of properties is
defined to qualify (or specialize) the managed resources so that they can
be meaningfully interpreted by client applications. Literals are used for
these properties, which include: "access", "detail", "label", "resolve",
"role", and "type". For more information see

     http://www2.harcourt-international.com/~tony/doi/yads/DObject.html
or

I'm pleased to announce that the first W3C RDF Core Working Group
Working Draft has been published:

  Refactoring RDF/XML Syntax
    W3C Working Draft, 06 September 2001
    Dave Beckett (editor)
  http://www.w3.org/TR/2001/WD-rdf-syntax-grammar-20010906/

This document re-represents the current RDF XML syntax using the XML
Infoset as one approach to clarifying and formalising how the XML
syntax generates RDF models.

We are looking for feedback on this approach, and suggestions for
other technologies or methods that can help this formalisation.  I
collected links to several previously-suggested approaches in the
reference sections that might be good starting places.
