Hi Robin,

I understand the protocol, it's very clear, but what I am asking is, is there a list somewhere of package formats, and their internal structures (e.g., what metadata formats are allowed, how are relationships between multipart objects like a thesis and its two supplemental files described, etc.). Marco used BagIt as an example, and my own institution would use BagIt as a way of moving groups of related files around and storing them together, but, to draw a parallel between SWORD and BagIt, both are just containers that are agnostic to the payloads they carry. METS is the same. Tools that define the container only handle half the process of data exchange; what we need are a set of profiles or other ways of specifying the details of how the payload is structured so that once it is removed from the container, other applications know how to reassemble it.

If such a list or registry doesn't exist, would there be interest in starting one, and describing the packaging formats the community is using (and willing to share) in a standardized way, as is done with METS profiles or DC application profiles?
