Re: PROV-ISSUE-149 (revision-asserter): Why does revision record include an asserter? [Data Model]

Hi Luc,

OK, but even if we distinguish "the agent who decides that a fact is
true" from "the agent who asserts that fact", then I don't see why
Revision is any different from any other assertion.

Thanks,
Simon

This is no different from any other assertion: it is always in some asserter's perspective that the assertion is true. We don't include the asserter explicitly in Used, Generated, Derived or other records, so why do we for Revision?
