Re: Fedora Triple-stores, Kowari, RDF.
We are currently employing MPTStore for our eSciDoc project, which makes
reasonable use of the triple store. Our experience with Kowari has been
painfull and frustrating. MPTStore is quite the opposite, but we share
your concerns regarding conformance to standards like Sparql.
One very promising replacement for Kowari seems to be Mulgara
(http://www.mulgara.org/). The Topaz people have gained a lot of
experience with that product, so maybe it is worth the effort to get in
touch with them.
