Actually, I don't know the upper limit (number of object, database size,

The binary package contains javadoc generated docs. That's all documentation
available.

We are using ozone with Cocoon (servlet). Somebody else is working on Enhydra -
ozone intergration. So far, I don't know any project that uses ozone in a
non-pure-Java environment.
