Hei Erwan,
thanx for your offer. Maybe at some point somebody will have a look on it.
we keep in touch - and by the way: the presentation on OrbisGIS looks
promising!

Hi,
I have created a wrapper from GDMS datasource to featureCollection but
it's just a converter.
If someone is interested, I can explain how to use GDMS api.
See u.

Erwan,
This sounds pretty nifty. This would tie in nicely to JUMP's DataStore
framework (which handles streaming data from a remote store and caching
it for viewing and manipulation purposes). It should be easy to
develop
DataStore drivers for GDBMS data sources.
Hopefully someone will get interested in this and take this on.
