Re: status of xsd:duration in OWL (and RIF and SPARQL) - ACTION-164: RDF WG

Just to help the technical issues here:

is the diff file for duration between the version OWL 2 referred to back then and now. I am sorry but the diff did not replace the relative URI-s to absolute ones, ie, the diagrams are not in the file, but the diff can help nevertheless.

I did not go into the details but there seem to be quite a lot of changes on duration. I do not know whether those have any effect on the considerations that Michael listed last night.
