Heh, I guess I just need a call to action. :-o

I completely agree, but we also need a lower-level API that the higher-
level (JSP-170 level) API is a subset of, a simple API for file system
providers and for implementations that simply don't need the complexity
of JSR-170 (either from an installation, implementation or footprint
standpoint), a simple API that still has metadata support. Not sure how
to do that, but it IMO probably should be a requirement unless we're
going to let JSPWiki become a heavyweight-only application. I kinda like
the ability to just use a simple file system provider sometimes (and in
fact, ended up adding a file backend my XNodeStore a long time after
implementing a Xindice, Exist, and finally BerkeleyDB DB backends). Also,
for a lot of ISPs (mine, forinstance), it may be difficult to manage a
DB-based backend, even completely embedded. I like being able to simply
copy that 'pages' directory between version upgrades.

[not sure how lucid that last paragraph was but I'm short of time to
go back and edit it.]

Okay, will begin investigating this with more attention...
