We agreed to remove the AQ terms from prov-o.owl, and make a separate prov-aq.owl to define the terms from AQ.
Then, all OWL files would be concatenated and made available at the PROV namespace (http://www.w3.org/ns/prov).
The provenance of the concatenation would also be included when requesting the namespace.
The mechanics have not been fully implemented, so this will take some collaboration to finish up.

I dont' recall the details, but that might just be the last copy of PROV-O.owl before we took out the AQ terms.
So, feel free to remove anything in prov-aq.ttl that is not from the AQ note.

If you don't need those, then clean them out. They were part of the PROV-O annotations that guide the HTML cross reference generation code.

Yes.

Not sure. Relatively complete? :-)

No.

It requires PROV-AQ editor review and guidance. We can help discuss and implement things if needed.

http://www.w3.org/TR/prov-o/ says:

[[
The namespace for all PROV-O terms is http://www.w3.org/ns/prov#.
The OWL encoding of the PROV Ontology is available here.
]]

Where "here" will become http://www.w3.org/ns/prov-o.owl

So, I suggest that AQ.html links to http://www.w3.org/ns/prov-aq.owl

Ivan is the gatekeeper for getting documents into http://www.w3.org/ns (via CVS)

It was decided that the OWL files NOT be in the /tr path because that would "freeze" them and it would be hard to update.
But we have "free reign" in /ns.

Tim
