As for interacting with the map, I'd like to at least see users be able to open their data to others for modification.

Yeah, full modification is something we're interested in, and have already built a pretty decent backend, see http://geoserver.org/display/GEOS/Versioning+WFS Though a crazy distributed modification history would be awesome, the way I'd start (and am starting), is to tie modification history to an individual data layer. A user has ownership over that, and can choose to open it to others. So it'd be like open source software, with a central repository that is the definitive version. Eventually would support branches, but there would still be the notion of the dataset. So in composing a map you'd pick the data layers, and if you wanted to change those you'd have to get your contributions back to the original, or else go through a major act of 'forking', establishing your own definitive version. But no matter what I'd like to see a user able to upload data and then encourage others to edit it, and versioning changes should help a lot for people to feel better about opening up their data. best regards, Chris -- Chris Holmes OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Geoserver-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/geoserver-devel
