Thanks a lot for the pointers, Kerry, and thanks also for raising the question of what should be the "scope" of a possible contribution from the SDW WG to modelling provenance. My personal view: When I was talking about "alignment" I was thinking of best practices on the re-use of existing vocabularies (e.g., PROV) for representing existing provenance models - as the relevant parts of ISO 19115. As far as metadata are concerned, there are currently growing efforts towards cross-domain interoperability, and a number of initiatives / activities on provenance, working on the creation of new vocabularies (see, e.g., the W3C DWBP WG, RDA) If we are going to work on provenance, my understanding is that we should aim at providing an RDF representation of the provenance models used in the geo domain that can also be re-used in other contexts. The objective is twofold: 1. Enabling sharing of spatial meta/data across domains and platforms 2. Contributing solutions developed in the geo domain to other communities, who may be totally unaware that what they are working on has already been. In terms of design principles, this might imply the definition of a "core" part (the cross-domain component), and possibly an "extension", addressing domain-specific requirements. In both cases, we should try as much as possibly to focus on the re-use of existing vocabularies. Defining new terms should be considered as the last option, and should take into account their possible cross-domain re-use. Actually, I think these principles apply to all the vocs in scope with our WG - or, at least, to those under the umbrella of the BP deliverable and to the Time Ontology.
