Re: PROV comments from Clark&Parsia

Dear Paul,

Thank you for the response. As much as we don't agree with the design
rationale, we accept the response from the WG.

We would have liked if PROV-O was more tightly integrated with PROV-DM
and PROV-CONSTRAINTS which both use PROV-N. We understand the
rationale that the WG wants to keep PROV-O tractable and encourages
developers to extend it. However, as pointed out earlier by my
colleague Hector, not having a normative mapping between
PROV-DM/PROV-N and PROV-O makes it really hard for developers like us
to extend PROV-O to encode these inferences and constraints. I'm not
saying this to raise a new issue but to provide feedback for future
PROV development.

Best,
Evren
