I got the impression that it is. It's probably not been updated for
a long time; I think not even to Zope 2, but I may be mistaken.

It was never released as open source, so it isn't floating around except
probably at Zope Corporation somewhere.

Obviously ZClasses are heavy, but tabular data in Python goes in some
kind of object anyway, so it's rather hard to avoid *objects*, unless you use
some external database. MetaKit has a nice Python interface and is lightweight,
for instance. I haven't heard of anyone integrating it with Zope yet,


Anyway, Python objects are lightweight enough for most purposes.

I'm not entirely sure why the idea of ZTables went away so completely. 
Python tables in the ZODB combined with the catalog should make for an
interesting system to play with. Though perhaps there are products
out there that actually do this. Come to think of it, MetaPublisher
(not to be confused with MetaKit) can use a ZODB backend, can't it?
