You can indeed use Mulgara.
You will have to amend your fedora.fcfg file to configure Fedora to use the
Mulgara triplestore - you should be able to find documentation for this.
Then you could include the things you want to index in the RELS-EXT
datastream using RDF, and use iTQL as a query language to search.
Take a look at the resource index documentation. You will find a web query
interface under http://your-fedora-server/fedora/risearch.
For information on Mulgara's iTQL query language, take a look here:
http://docs.mulgara.org/itqlcommands/select.html

Subject: [Fedora-commons-users] Searching for the object using some
advancedquery language
Hi,
In our organization we decided to use Fedora as Digital Object Store.
At the moment we are storing, accessing and (simple) searching the object
using the webservice interface API as described in the apia and apiam. The
objects are stored with several datastreams. Now we are at the point where
we want to do more advanced object searching using some query language (like
SQL). The apia and apiam are quite limited when it comes to object searching
and it only supports searching in the Dublin Core format and we would like
to do searching in our custom formats, which could be an RDF format. Is
there any API or plugin for the Fedora that support object searching using
some advanced query language. I read that Fedora has a Mulgara plugin, which
actually provides a query language for the RDF based formats, but couldn't
find anything about it on the Fedora site. Are there any links on how to get
started on getting Fedora working with Mulgara or are there some other
alternative solutions on that.
thx in advance, Piotr
