Dear Karl, First, I'd like to thank you for all the comments that you submitted for the WSDL RDF mapping, they were all very useful, and you'll get from me emails regarding how we resolved any issues you raised. However, I'm unsure what you mean in [1]: > About http://www.w3.org/TR/2006/WD-wsdl20-rdf-20060518/#genericext > > The group has touched something which is broader than WSDL-RDF 2.0. > How to declare extension to an XML language. This is a very > interesting topic which is related to the previous work of QA WG: > [Specification Guidelines][1] and [Variability in Specifications][2]. > It also touches issues discussed by the TAG about versioning and > extensibility of languages. I think it would be very valuable to have > your expertise shared outside of your WG. Would someone volunteer to > write something about the mechanism in RDF to handle extensions in XML > and send it to www-qa@w3.org and www-tag@w3.org In the RDF mapping, we only turn unknown extensions into literals in RDF. In fact, we do have a few RDF classes and properties around the extensibility attributes, but we realized that attributes must also be canonicalized so we will, in the next version of the RDF mapping, just have one property from an extended component to an unrecognized optional extension, with the object of the triple being the XML literal containing a canonicalization of that extension. In summary, I don't quite think we have much expertise to share with the QA or TAG groups, but if you think otherwise, I'd be happy if you could clarify what you mean, please. 8-) Best regards, Jacek Kopecky editor of the WSDL RDF mapping draft [1] http://lists.w3.org/Archives/Public/public-ws-desc-comments/2006Aug/0004.html
