I used those this week, with some success. I found the API a little
hard to work with - I think it has RDF influences and I had a bit of a
time getting my brain to wrap to that. But borrowing some ideas from
zope.agxassociation, I made a Field and a property that uses that
Field and got a pleasantly working system that masks some of the
things that I had a hard time wrapping my head around (roles, groups,

One of these days, I'm going to need to learn what GPL really means,
and how it should affect my choices of libraries that are open source
that seem comparatively similar otherwise but for the license. I guess
I need to revisit all the code we're using and check the licenses
again, since we might be branching into some new business models.

Ooo. I'll have to take a look at that one.

I was looking at this earlier this week, but it seemed incomplete...
Actually, in subversion, the interfaces.py module ends after an
opening parenthesis. Was I looking in the wrong place?
I liked what I generally saw of agxassociation, but saw no concept of
removing associations (only adding them). schoolbell.relationships
(from Schoolbell 1.2.x) seemed a bit more complete.
I hope it makes it into the Zope core. Now that I have relationships
in my application, a whole new world has opened up - especially now
that I've rigged up a system that doesn't require me to think in RDF.
