Well, yes, this is more what I'm angling at, I guess (and more diplomatically, thanks Ryan). Perhaps, rather than worry about a perfect mapping, we should focus on a practical mapping between the two. There are quite a few indexes that the bib context set opens up that are useful, especially in the context of OpenURL resolving (volume, issue, etc. come to mind, atitle/jtitle as well - but these I see as a quite a bit trickier).

The only problem I have with this logic is that: In many of the same places that SRU is trying to be implemented, we are also trying to implement OpenURL, so why can't we make that process as painless as can be? I understand abstracting this, certainly, but at some point concessions need to made to the communities that actually want to use this. -Ross.
