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

(Removing some mailing lists from the CC list, because that seems to be a purely OWL, and possibly RIF WG discussion...)

I am not commenting on the technical issue. The current status of the WG is based on the latest extension of its charter announced in:

https://lists.w3.org/Archives/Member/w3c-ac-members/2011OctDec/0066.html

in my reading that does not allow adding new datatypes, or change the semantics of existing ones (except if there are technical issues created by the final version of the XSD document compared to the version we used when OWL 2 was finalized). Doing so would not mean an 'edited' OWL 2 document, but a new version instead. That would require rechartering the OWL WG or creating a new group.

I am sorry, just stating what I see are the administrative facts...
