Re: PROV-ISSUE-94 (pe-attributes): are process executions characterized in the same way as entities? [Conceptual Model]

My qualm here is that the standard is better if it is simpler, and if
it is only constraining where there is a clear benefit.

The impetus for entities to have characterising attributes, as I
understand, is that we need to be clear which of multiple perspectives
on a thing we are making an assertion about when giving its
provenance, e.g. "the report", "version 1 of the report", or "version
1 of the report on Simon's PC".

Is there similar need for process executions to have characterising
attributes, or is it just making the standard more complex?

I also note that there was argument against process execution being a
sub-class of entity, but this would remove further distinction between
them.

Thanks,
Simon
