We don't have a clear vision of that either.

We are thinking about providing a patch for DSpace that exposes the
dublin core metadata of items (and searches!) as RDF, this would allow
it to integrate with PB without scraping.

An easier fix would be to allow DSpace to return a 'x-dspace:' header in
the HTTP response, thus identifying a web site that runs DSpace and
allowing the scraping to happen (for example via the OAI-PMH interface,
instead that by scraping the HTML page, that might change from
installation to installation).

Although my group is still heavily involved with dspace, you have to
understand that it's an open source community and therefore they have to
buy into the thing before accepting the patch (and we have to write it
first too ;-)

But this is the general plan for dspace 1.x

As for dspace 2.0, we would like to incorporate longwell and RDF triple
store more deeply into the architecture, but it's way too early for that.
