Formalizing PROV-Constraints in OWL?

In the PROV-O call today [1],  we agreed that it would be useful to
have a formalization of PROV-Constraints in OWL.

In particular we are thinking about section 5, things like
functionality, reflexibility, etc., rather than the long inferences
and time order constraints which would be much harder to do in OWL
alone.

We feel the PROV-O community in particular would mainly see use for
validation checking rather than inferences, so that they can validate
their produced PROV-O.


Paul has also started work on [3] which uses SPARQL queries to create
inferences [4] and constraints [5] - this could form part of a
validator tool, which would be very useful.

We know Paolo and Khalid also published a paper at IPAW for checking
PROV using DataLog [6][7]


So we are looking for volunteers for doing similar work with OWL,
ideas on how we should proceed, and perhaps a schedule for this.

Currently we have:

* Jun
* Stian
* Paul?
* Tim (?)
* Khalid, Paolo? (IPAW work on Datalog)

Anyone else?


Our current idea is to go through (mainly) section 5 of
PROV-Constraint [8] - modulo any later changes - and model these in a
simple OWL file that extends PROV-O. This can be OWL-Full. We won't
address time constraints or complex inferences.

We're also looking for ways to test this.


In the interest of getting started, I've made a template OWL in Mercurial. [9]
Feel free to modify!
