Please note that we have just switched from SVN to Bazaar. I'll update
the info on the web page RSN, in short:

The official trunk repositories are locate at:

I have no experience with Oracle Forms, but I seem to remember that the
previous maintainers (James Thompson, Jason Cater) used GNUe Forms to
replace Oracle Forms apps.

In principle, this should be possible, but I don't know whether all
available options in Oracle Forms are mirrored in GNUe Forms.

It might even be possible that GNUe reads Oracle's native format and
creates the internal data structures from that rather going the step
through XML format.

So far, it was not an explicit target, but since this is an FSF
high-priority project, I'd rather see it implemented in GNUe than in an
independent new tool. Also, I believe that GNUe is closer to that target
than anything else out there.

If you are interested in contributing to GNUe to implement compatibility
with Oracle Forms, your work will be much appreciated, and I will try to
help you as much as I can.

This is something which would have to be checked with the licensing team
of FSF in detail. Maybe the fact that the database drivers are plugins
which use a kind of "standard interface", and there are several drivers
using the same plugin, might play a role here.

Yes. Unstable releases contain "alpha", "beta", "pre" or "rc" in the
version number.
