Certainly, RDF-MT says nothing about change over time, but I was asking
about the use of the term log:semantics, which is defined elsewhere. You
seemed to be suggesting that log:semantics is functional, but there's no
way to make that work in with http: URIs.

Handling different graphs from the same source is basically the same as
handling different graphs from different sources. You just have to be
careful about what you're saying. (That is, "Resource X asserted Y at
time Z" is more useful than "Resource X asserted Y".)
