Hi Lenya devs,
just a heads-up: The JCR mapping code is being moved from
Graffito to Jackrabbit:

Maybe the move is not the important aspect here, but the fact
that quite a lot of people are interested in such a mapping layer.
I still think that Lenya won't get more acceptance in enterprise
level environments without a performant, transactional repository.
The JCR mapping could certainly help to base Lenya on JCR.
+10 for an enterprise-grade backend. i'm not familiar with JCR at all,
but i have experimented some with eXist (an XML database) as a possible
lenya backend and have created a prototype that relied on eXist for
storage of data-centric xml. i love that approach, because you interact
with the db just like you would with a plain xml file (xpath/xquery),
which i think is more user-appealing than a java API, and the database
magic makes it reasonably fast (though orders of magnitude slower than
an rdbms), and caching can do the rest.
i've spoken to some JCR fans at cocoongt 06, and some stuff sounded
cool, but they had to admit that any existing xpath/xquery interfaces
are quite rudimentary...
perhaps we could dedicate a few hours of the hackthon to a discussion
about possible backends? i'd be willing to give a short presentation
about eXist, and i would appreciate if andreas could give an overview of
our existing system and of JCR. michael r., will you make it to zurich?
i'd love to hear a first-hand primer of what EJB could do for us...
if you think that makes sense, we could videotape the presetations, so
that all list members can benefit from them...
