I think PROAI may well be the answer to your needs.
My recollection is that the default configuration delivers oai_dc from a
datastream also called oai_dc - which, of course, doesn't exist unless
you create it. As Ben said, you can set it to any datastream you like.
Further, I recall that you can deliver a metadata return from a
disseminator; thus in our new repository (September next) there will not
necessarily be meaningful oai_dc in the objects but we shall respond to
an oai_dc call with a disseminator which generates the metadata on the
fly from the MODS that *does* exist.

Subject: [fcrepo-dev] oai_dc, reserved namespace, and Fedora
We've been repeatedly told on the Fedora development list that the
oai_dc data stream was misnamed to begin with, and we shouldn't use it
for external facing data. Additionally, we *can't* use it for externally
facing data, because since it is an internal-use datastream, we can't
put an external-facing identifier in the dc:identifier field in that
datastream.
However, the OAI PMH standard reserves oai_dc as a metadata prefix
(<http://www.openarchives.org/OAI/openarchivesprotocol.html#MetadataName
spaces>).
This is causing us problems with at least one organization we want to
have harvest our records. We can work around this, probably, by
customizing our harvester to publish a different datastream when oai_dc
is requested. But this seems imperfect. If the Fedora object has a
datastream with a name that means "I am the OMI PMH datastream to be
harvested", it's going to continue to be problematic for users.
Is there any plan to change the name of that datastream to something
that hasn't been reserved to mean something else?
Thanks,
-Deborah
