Hi Ben, Rune, and other folks using Mulgara with Fedora,
Note that you can today run SPARQL queries directly against Mulgara
when it's configured to run in non-embedded ("remote") mode. Of
course, it's also nice for people/apps to be able to count on a
repository endpoint that's SPARQL-aware, even if it's just passing
queries through to Mulgara (whether embedded or not).
Eddie Shin and I have been discussing this a bit as well. Where we
left it last was the recognition that we'd both like to eventually rid
Fedora of it's use of Trippi (one big reason: Trippi hides Mulgara's
transaction semantics). But right now, risearch (the servlet that
responds to RI queries in various languages) is actually implemented
as part of trippi-core. So we'd effectively need a replacement for
risearch. And there are some unresolved questions there. For
example, do we just replace it with a SPARQL endpoint? If so, what
about people who currently depend on iTQL-only features? Or those who
only need/want SPO support? Your reactions to these questions are
very welcome.
On the other hand, due to the way risearch works, an incremental
change to the trippi-mulgara package could enable this off the bat.
Any takers?...see
http://trippi.svn.sourceforge.net/viewvc/trippi/trunk/src/java/org/trippi/impl/mulgara/
and respond to the fedora-commons-developers list if interested...
Thanks,
Chris
