Hi,

I thought we should discuss this issue since it seems more about the alignment of PROV-O and PROV-DM (and how the constraints fit into this) than about the constraints document.  

Please let me know if you agree/disagree with the response below.  I propose to respond by explaining that it is out of scope of the current documents but may need to be addressed later (e.g. if we wanted to fully OWL-ify the constraints.)  

Marked pending review for now.

ISSUE-556 (time-qualification)

Original email: http://lists.w3.org/Archives/Public/public-prov-comments/2012Oct/0004.html
Tracker: http://www.w3.org/2011/prov/track/issues/556
Summary: Are there missing constraints to relate qualified and unqualified start/end times?
Group response:
PROV-CONSTRAINTS defines constraints in terms of the abstract syntax of PROV-DM.
The group has decided not to explicitly specify the mapping from PROV-O representations to PROV-DM and back (although there is a partial, but not up-to-date, alignment at http://www.w3.org/2011/prov/wiki/ProvRDF), but this might be done in the future or as a Note.
The group has also decided not to specify the constraints using OWL explicitly, but this might also be done in the future or as a Note.
It appears natural that constraints such as the author proposes will be needed to apply constraints to PROV-O documents directly, but this is outside the scope of the specifications.
