I thought it had been mentioned - and positively - but maybe private mail.
My take is:
We do not intend to overlap with RDF if we can avoid it - we want the
systems to be complementary. Since I imagine that RDF metadata will be
ubiquitous (i.e. every responsible XML document author will include
RDF-based metadata) I assume that XSchemas will include RDF-based metadata.
There seem to be two ways this might occur:
- metadata "at the head of the XShema" - what is this XSchema about - who
owns it - how can it be used - who has validated it, etc
- metadata that the XSchema might provide for documents or their authors -
help, links, etc.
My feeling - at this early stage - was that we are certainly not inventing
a new syntax for metadata (even in a very limited fashion) but we are
thinking about the metacontent that an XSchema might deliver. I would be
very hesitant at this stage of providing anything much more than name-value
metadata.
I have no problem with many contentSpecs in an XSchema including RDF:*, but
how it might be used is probably too early. In any case we have to be very
careful not to overstretch what we are doing.
