We've been having a lot of feedback on the latest draft of the Simple
DC profile in RDF/XML (*):
http://dublincore.org/documents/2001/11/28/dcmes-xml/
about the Appendix B that includes a W3C XML Schema for the profile:
http://dublincore.org/documents/2001/11/28/dcmes-xml/#appB
Although this W3C XML Schema is for information only, it seems that
there are many people interested in using it or something related.
The current schema doesn't seem to be quite right and given the
ammount of interest, it seems best to not deal with it in this
document.
After discussion with the DCMI, I propose to remove it for now and
publish the DC Simple doc as it stands, the majority of which has
been stable for a long time.
The next step would for some group to spend more time considering
Schema validation of DC in RDF/XML (or other XML formats) such as W3C
XML Schema, RELAX NG, .... Then the proper time can be spent getting
it right, re-usable, interoperable and valid (maybe for the full
qualified DC in RDF/XML).
I've stuck my latest attempts here:
http://ilrt.org/discovery/2002/01/dcxml-xsd/
where the top-level schema is
http://ilrt.org/discovery/2002/01/dcxml-xsd/dcmes-xml-xsd.xsd
importing
http://ilrt.org/discovery/2002/01/dcxml-xsd/dcmes-dc.xsd
http://ilrt.org/discovery/2002/01/dcxml-xsd/dcmes-rdf.xsd
(plus the XML namespace)
and there are 4 instance documents
http://ilrt.org/discovery/2002/01/dcxml-xsd/ex0.dcml
to ex3.dcxml
http://www.w3.org/2001/03/webdata/xsv
XSV 1.203.2.42/1.106.2.22 of 2002/01/11 16:40:28
validates all the schemas and the examples (*.dcxml) above
With my RDF/XML Syntax editors hat on, I wrote an RELAXNG schema
for RDF/XML and it seems to be working out quite well
