JSE: I respect the fact that there will be metadata elements for with provenance needs to be maintained, and other elements for which such "care and feeding" is not necessarily required. BUT WHO DECIDES (and when)? Certainly NOT the system designer. This should be, minimally, a curatorial decision, probably driven by institutional policy (however one wishes to define "institutional"). The provenance issue we have been discussing seems related to a thread that came up more than a month ago, in the context of the History System, where the question of "what events do we record? and what metadata should we save?" was raised. Again, such decisions should NOT be a system design issue, but rather should be driven by (in the HS case) event-triggered *policies*. ("Do thisAction when thatEvent fires and theseConditions are true...") These are but two examples of the "lifecycle management of objects" concept that Mick introduced about two weeks ago: the ability to associate policies with digital objects for a variety of purposes, including (and esp.) to facilitate their management. Just as RDF-based technologies promise to transform the discovery and retrieval of resources, they can also transform their management, by providing a means of specifying the scope of policies based upon the characteristics and relationships of objects rather than simply their position in hierarchies.
