Re: Note: DSpace and RDF

Mick,

Just a couple of things you may want to address in:

> 	<ftp://ftp.dspace.org/pub/doso/dspace-rdf.htm>

before www-rdf-dspace is announced.

In the section "How, specifically, should DSpace use RDF, both 
initially and longer-term?", it says: 

> Succeeding with this approach requires resolving the low-level

Since there is no semantic web WG at the W3C it's not clear what
WG you are referring to.

The RDFCore WG, whose charter is:

 http://www.w3.org/2001/sw/RDFCoreWGCharter

has a somewhat related but different deliverable listed in its charter:

  [[
  provide an account of the relationship between RDF and the XML 
  family of technologies (particularly Schemas and Infoset/Query) 
  ]]

The Annotated DAML+OIL walk-thru:

 http://www.daml.org/2001/03/daml+oil-walkthru.html

contains a section [the document seems to contain some broken NAME 
attributes so I can't give you a usable fragment] that describes a 
way to use XML schema datatypes in an DAML ontology.  Does this 
address the issue you refer to above?

Also, the document says:

A link to Peter's proposal should be added.
