To get a revision, we could say that you can use the Revision-Selector
header
with a stable URL to a versioned resource.
GET /repo/versioned-resources/vr873
Revision-Selector: id rev-73
To get a working resource, we could say that you can use the Workspace
header
with a stable URL to a versioned resource.

I know our server will not answer questions like this on stable URL's,
i.e. workspace revision selection is done only on user URL space, not on the
stable URL space (which are really just database id's).
So you'd have to bind that resource somewhere into the user namespace
before you could ask the question.
We could provide a mechanism for finding out what user URL
in a particular workspace is currently mapped to the versioned resource
identified by a particular stable URL.
This is probably a REPORT, since it is not naturally
a property of any particular resource. Should we provide such a REPORT?
And if so, any suggestions of what to call it?
Cheers,
Geoff
