I've spoken with a couple of the GeoTools folks about helping to maintain their projection code, which uses the ESPG database. This is of interest to me because it is a comprehensive (and working) projection library written in Java that we can incorporate into OpenJUMP.
I don't know if there are any GeoTools/UDig developers that would like to participate in this OSGeo labs project that is under discussion, but I am interested. Perhaps I could help coordinate developments with GeoTools as part of what I hope will be my eventual support of projection code in GeoTools? I could definitely represent, at least unofficially, the OpenJUMP community. I'll subscribe to the mailing list that Frank set up.

I am still interested in this concept though I haven't followed up on it yet. My hope was that we could treat a variety of coordinate system activities as one Project from an OSGeo point of view. This helps get us past the issue that some (all?) of them are rather small in terms of teams to justify the full "OSGeo project treatment". But more importantly it would give us a forum to cooperate. Sharing things like coordinate system dictionaries, test suites and such. My hopes for participants include: proj4js proj.4 (the version of PROJ.4 that I maintain) libproj4 (the projection-only library maintained by Gerald Evenden) OSGSpatialReference (GDAL coordinate system translation classes) CS-Map (the recently open sourced library from Norm Olsen) I'm also hopeful that folks from GeoTools, and OSSIM who maintain their own projections code would participate to take advantage of the dictionaries and test suites even though their libraries wouldn't be part of the project. This is a somewhat unorthodox arrangement so I've hesitated a bit to initiate things. Also, it obviously needs agreement from several parties. :-) In the interest of moving on a bit, I've created a wiki page: http://wiki.osgeo.org/index.php/MetaCRS I've also created a mailing list.
