Version histories do not add anything to our system at this point. We will support the version-tree, though. That said: I *do* know how/what a version history resource would be within our system, and could provide the functionality; it is simply that the client doesn't need it at this time. [ and, in fact, I don't see its purpose in general. if you could somehow browse and acquire an HREF to a history, then you'd have a resource that tells you a bunch of version resources. But that doesn't tell you anything about the version-controlled resources (e.g. they're layout/structure, how they were made visible to users). So basically, you have an unstructured index to some data, but without a way to properly structure it. Seems a bit pointless :-) ] >... > Yes, the DAV:version-tree report lets you say what properties you want > to see.

There is the mapping problem back to the version-controlled resources (VCR). Hmm. I guess "detached" version histories aren't useful. When they are still hooked in via a VCR, then it handy because you can link from a VCR to a history to versions within a property report. Oh, whoops. I think that I will have version histories. I forgot that I was planning to do prop reports just like that for some functionality (specifically, to call up a change log with users, times, comments). hehe... call me clueless :-) Cheers, -g -- Greg Stein, http://www.lyra.org/
