Larry - Thanks for the helpful response. I've still been unable to do a lookup or a get, but I'm concentrating right now on walking through the hierarchy to learn what turns up and what kind of properties I'll find. When I get comfortable with that, I'll re-read your message and try again.

This path looks like you've traversed some communities and collections: > http://[server]:8080/lni/dav/dso_123456789%241/dso_123456789%242/dso_123 456789%243 You can also get a resource URL by doing a "lookup" on a Handle, e.g. GET on http://[server]:8080/lni/dav/lookup/handle/123456789/42 returns a Location: header with the URL. I don't think it works on Bitstreams, though. Anyway, if you do a PROPFIND on that resource you're trying to GET, look at the value for "type" (in the "http://www.dspace.org/xmlns/dspace"; namespace). It'll be an empty element for the DSpace object type, either <collection/>, <community/>, <item/>, <bitstream/> Typically, the Bitstream resources have a path ending in ..../bitstream_{n}.{suffix}, e.g. .../bitstream_3.pdf So, I think the problem here is that you've got a resource for which GET isn't implemented.
