On the metadata provenance question: -- I stick by my statement that libraries have not traditionally tracked provenance for *descriptive* metadata since it's seen as very context-sensitive, subject to change, and not of great interest for content management over time (the provenance, that is, not the metadata itself). -- However there are some newer kinds of metadata for which the community seems to want to track provenance: namely, preservation metadata. The new schema from the National Library of New Zealand makes a big point of capturing and preserving provenance metadata related to preservation activities -- i.e. what was done to the digital object over time in order to preserve it. -- Someone (maybe Eric?) made the point that in a world where metadata is coming from god knows where and being merged together to describe an item it might be nice to know where that metadata *came from * (i.e. the metadata source, in the strictest sense of the word provenance). I agree with that point of view, but question whether it extends to *subsequent* changes to the metadata once it's in our environment. >The reason I used these comments (apart from the fact that MacKenzie is >the domain expert here) is that they back up a concern of mine: I'm >getting quite concerned about the complexity this "metadata provenance" >issue is bringing.

If a source of complexity can be avoided I think it should be. Good point. But let's think about the distinctions I'm trying to make between *types* of metadata (i.e. descriptive vs. long-term management) and *sources* of metadata vs. tracking every change over time... different problems, different priorities for the data curators...
