So you are assuming a "list" somewhere that is not part of the info registry. So info:xv is all that would be in the registry, and the rest (i.e. what is represented by "/1/mods/resourceType/1/textual") would be elsewhere. OK, that said, I still have trouble with some of the levels. I prefer that the namespace be one-to-one with a registration authority, because that is how the registry appears to be set up. To do otherwise would require another level in the registry, and I think we're getting almost into structural changes here. (Which I'm not against if someone wants to re-think the registry structure, but it should happen explicitly). The "registration authority" level (your "/1/") would then go away. Only LC could create "xv" identifiers. If that's the case, then the upper level could be "info:mods" or it could be "info:lc_xv" so that others could also have their "xv" space. That's a quibble -- semantically "xv" seems non-specific so it doesn't make total sense that it should belong to one organization. I think you were wanting to make it general, but I believe that is the generality that info is supplying. I also have a question about: "info:xv/1/mods/resourceType/2/cartoon the '1' is still LC, but the '2' is OCLC who has registered an additional resource type." I'm not clear where it is the OCLC has "registered" this type. This assumes that there is a registry elsewhere that stores the actual info:xv values. This is kind of what was confusing me when I said that if these items are in a registry down to this specific level, then you have a registry but not a list. Now I'm not sure what we've got: registries down to the item level? lists that can be expressed as info:xv URI's? If the latter, how will those lists be maintained and by whom? Do they have a particular structure that allows the URI's to be derived? I feel like I'm missing a piece of the puzzle. -- ------------------------------------- Karen Coyle Digital Library Specialist http://www.kcoyle.net Ph: 510-540-7596 Fax: 510-848-3913 --------------------------------------
