SWBPD note on QCRs

Peter, Ian,

In the SW Best Practices group Alan Rector and I have been working on a 
note on QCRs, with the intention of providing guidance for ontology 
engineers. The note is mainly based on the work-arounds and proposals we 
developed during the WebOnt discussions about this. The current draft 
[1] has been lying around for a year or so (there were some formatting 
updates, but nothing major) and we would like to finish this now.

Patterns 1 & 2 in [1] are work-arounds for OWL as it is. I want to draw 
your attention to pattern 3, a "non-endorsed OWL extension", which 
actually comes from the WebOnt resolution on QCRs [2, end of the email].

I was looking at OWL 1.1 documents [3, 4] to see what kind of syntax you 
propose. I found the abstract syntax, but no mapping to RDF/XML triples. 
I have two questions:

- Is there a proposal for a OWL 1.1 RDF/XML representation of QCRs?

- What do you think of the proposed RDF/XML syntax in pattern 3 of [1]? 
Comments and/or proposals for alternatives would be very much appreciated.

Thanks.

Best,
Guus
