I found it very interesting, and I think it is a shame that so few people manifested interest about it - especially when so many people are concerned about RDF syntax and RDF-enabling any XML document...
A few comments :
- introduction of section 3.3 reads
"Then we describe the rules for the extended link as a whole."
but there is no such rules (as I understand it, they have been removed from older versions)
- about expanding QNames by concatenation :
as I already mentionned it in the rdf-interest list, I quite don't like the idea of concatenating a namespace with a tagname. Although I admit this can be reasonable with an RDF-dedicated namespace, this seems much more hazardous in any XML document.
The note suggests that when no xlink:arcrole is given, the element QName be so expanded and used as the RDF predicate. I would rather propose two appoaches when no xlink:arcrole is given :
* no triple is generated - the xlink:arcrole MUST be present to generate a triple
* an implicit arcrole is assumed, e.g. http://www.w3.org/1999/xlink/properties/arc
- about RDF predicates xlink:title, xlink:label :
how are they supposed to be expanded ?
http://www.w3.org/1999/xlinktitle and http://www.w3.org/1999/xlinklabel
(which strictly follows the concatenation rule but is obviously wrong ;-)
or
http://www.w3.org/1999/xlink/properties/title and http://www.w3.org/1999/xlink/properties/label
which sounds sane...
This should be clearly stated in the note.
