The EARL project http://www.w3.org/2001/03/earl (and other stuff from
http://www.w3.org/WAI/ER for humans to follow) - deals in provenance.

There are schemas and some discussions that provide further explanation of
how and why we did what we do, and there is some ongoing discussion about
whether we can simplify what we have so far.

EARL is an evaluation reporting language that was built in the context of
accessibility evaluations. One of the use cases is that different people or
tools may have different ideas of how accessible a particular thing is (even
to the extent of disagreeing whether it meets a fine-grained requirement).
Another is that a resource may change, so having a time for the provenance is
important too.

there are now a couple of different tools working with EARL, and we hope to
have more soon, so we might not have all the answers but we are facing the
same questions. (There are others on this list who have been working on it
and maybe able to expand on this...)

cheers

Charles
