Hi Eike,
One question, do you think that it could be interesting/valuable having
CDO as an implementation of the Eclipse File System ?.
I understand, that the idea of a repository and file system are
completely different. However, considering a CDO server or CDO
repository as directories and the CDO Resources as files it could be a
way of doing such an abstraction. Obviously, it would be a very
restricted file system, in which some operations would not be allowed.
I'm working on the integration of several fyle systems via EFS, and I
would like to integrate CDO repositories. Having EFS as the unique
abstraction which I have to work on, would be very helpful. Otherwise, I
would have to distinguish the URI of the artefact to treat it as a CDO
repository/resource or an EFS file store.
Cheers,
Adolfo.

Hi Adolfo,
Yes, I think this sounds like a great idea. If you want to work on this
and contribute the result I can offer you my help with internal
knowledge about CDO.
It could also be interesting to rethink the relation between a
CDORepository and its CDOResources. Currently all resources of a
repository form a flat list with each resource having a flat string
"path" (which is really more like an opaque id). It is imaginable that
we add more real structure by introducing a new system class:
CDOResourceFolder (or just CDOFolder). Just like CDOResource it would be
a CDOObject with system-defined features like name and contents. I'd
even suggest that we factor out a common base class CDOResourceElement
for name, path and thelike.
If you're interested I suggest that you file a Bugzilla where we can
continue our discussion...
Cheers

Hi Eike,
I'm glad you like the idea, especially if you consider "folding" the
repositories. When you have a lot of resources, they could better be
organized ;).
I have raised the enhancement requirement:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=246703
I can not invest too much time right now in providing a proper
implementation of the idea. But in one/two month time, I could do it,
especially if we have a proper design of how that CDO file system should
looks like.
Let's go on the discussion in the bugzilla ;)
Cheers,
Adolfo.

Hi Adolfo,
Don't worry about the time. We are not bored in the meantime ;-)
I'm looking forward to see the results of this effort!
Cheers
