Don't know the specifics about the engine being used, but we discussed
using the Plone storage mechanism, a few times, for spatial data. Just
didn't seem like a quick enough payoff to try anything out. At least
not on the surface.<br>
<br>
There was a thought that there might be something to start with though.<br>

<pre wrap="">Hi,
¿Does anyone know about similar projects using object oriented databases, such as db4objects[1], which is a GPL product with native engines for Java, Java ME, Mono, .NET, ...?
Cheers

David and All,
A nice up-and-coming open Java geodatabase format is H2 +
spatial extensions.
The H2 database is by the same guy that wrote that HSQL db. H2
has some good properties, most importantly, it's small (1 Mb),
works well in embedded mode, and is fast. Adding in spatial
data in JTS format, and providing a spatial index, is the
basic concept.
Two implementations that I know of are
1. The French research group IRSTV, lead programmer seems to
be Erwan Bocher.
<a class="moz-txt-link-freetext" href="http://geosysin.iict.ch/irstv-trac/wiki/H2spatial/Download">http://geosysin.iict.ch/irstv-trac/wiki/H2spatial/Download</a>
2. GeoTools has a H2 spatial module, written by Justin Deoliveira.
Here's a link to the compiled jars:
<a class="moz-txt-link-freetext" href="http://maven.geotools.fr/repository/org/geotools/gt2-h2/2.5-SNAPSHOT/">http://maven.geotools.fr/repository/org/geotools/gt2-h2/2.5-SNAPSHOT/</a>
Both are under active development.
regards,
-Frank

Hey Folks,
Just wondering if there is still thought out there from the previous
thread about a portable and open geodatabase. I came across the
nemesis project "an experimental finite element code.

Thought that might be a good place to start that is already using
