Hi Thorsten, Norman,
Here is the download page for Hibernate Spatial: http://
download.html. You'll find the Postgis provider near the bottom of
I'm aware that our documentation is still rather incomplete. So if
you have any question, just mail and I'll be happy to answer. You

I'm moving the Hibernate Spatial code away from the MAJAS project and
give it it's own home on org.hibernatespatial. I believe that such a
domain is a more natural home than org.postgis because one of the key
features of Hibernate is that it insulates you from the differences
between databases. The reason I started developing this library in
the first place, is that my clients use Oracle Spatial in production
but I rather develop on top of Postgis. So with Hibernate Spatial I
can simply switch databases during integration testing and roll-out.
During coding, I don't have to bother about the differences between
I agree with Norman and hope that we can collaborate on one Hibernate
Spatial code. And from there move up the tool chain (Hibernate Tools,
Seams, etc.) and extend these frameworks with spatial capabilities.
But for the reasons stated, I'm a bit apprehensive about developing
"with a focus on postgis". Out there, many organisations use MySQL,
Oracle, DB2 and Informix. They matter too, and equally.
Btw, there is also an NHibernate.spatial by Ricardo Stuven out there
for the .NET developers. I'm in contact with him, and we're thinking
about converging our code bases at some stage. If we could pull that
off and extend support to most databases, we'd have a tool that
greatly facilitates cross-platform, cross-database development.
