All,

We are now defining entity as follows:

/An entity is a thing one wants to provide provenance for. For the 
purpose of this specification, things can be physical, digital, 
conceptual, or otherwise; things may be real or imaginary./

Unfortunately, we also provide provenance for activities, etc.
Last week, we agreed we could query the provenance of anything that was 
identifiable.

So, the definition of entity is too broad.
How should it be revised?  Can reviewers think about it?

Regards,
Luc
