Yep, an RDF store within Moz would /calcitare asinus/.

In straight tech terms I guess it doesn't really matter whether the
underlying implementation is SQL-DB based or native - there may be
some advantages in the former, where issues like scalability can be
pushed to a different (totally solved) layer. But there may be a
danger hinted in your remark re. confusion. If there was a SQL DB
underlying an RDF store, there'd be temptation for developers to use
it at that layer, rather than the more interoperable triple layer.

I've a feeling I saw a recent RDF in SQL DB design doc, but can't find
the link - anyone got a ref? (Coincidentally I just stumbled on
another case, Steve Harris' updates to 3store [1]). If the Moz guys
do continue in the direction on the Wiki, it would be a shame for them
to have to reinvent the wheel.

Those Wiki pages give me a lot more optimism about RDF in Moz, I've
seen a few comments in the recent past suggesting movement away from
RDF with the familiar "too complicated, we can do this with XML"
argument. They may have more justification than usual, with Moz's
implementation being begun with the old RDF specs, I get the
impression of clunky hangovers (i.e. containers). But whatever the
history, now's the time the RDF capability could *really* be

A couple of avenues come to mind through which the Moz folks might be
further encouraged. One is SPARQL. It's exceedingly cool - are they
aware of this? The other would to present a prototype based on the
current build tree as a fait accompli. Anyone got a research student
with time on their hands? Once a store was integrated, the PiggyBank
material shows one good route to demoing the potential.

Redland does seem like a very good candidate, having native capability
on the different platforms, no need for a separate VM.
