RE: [ALL] RDF/A Primer Version

David/Ben,

I think Ben is right that this is not something that can be resolved
quickly...or rather the URI collision part isn't. (Speaking for myself I'm
happy to see dc:creator removed--it's always confused people.)

One part of the problem is that the whole point of RDF/A is to be able to
carry metadata within a 'normal' document. This means that *by definition*
we have what could be perceived as two resources at the same URL--we have an
XHTML document, and we have metadata for that document. Both are 'carried'
by the same set of XML elements, but how they are *processed* depends on the
agent retrieving them. It seems to me that the TAG work on fragment
identifiers does not allow for this possibility, since it says that if the
document is XHTML, then a fragment identifier must be referring to an XML
element. (In passing this seems wrong to me anyway, since it is supposed to
be up to the user agent to make use of the fragment identifier.)

Anyway, I'm not saying that this can't be resolved in some way that fits
with the TAG work, and I have some ideas that I would like to bounce around
the list, but I would again agree with Ben's point that we should go ahead
with the draft, but with an understanding that this work will continue.

Regards,

Mark
