I'm getting started on the design of a new system that would reconcile, merge, and synchronize changes made across numerous geospatial databases of common ancestry, on an ongoing basis. These databases are distributed across numerous different organizations that have an interest in eliminating duplication of effort.
I read that OpenGeo is working on a project called GeoGit, which is interesting but seems very much a work in progress.
Are there any other tools, projects, or research that would be worth looking into?
I do not want to reinvent the wheel, but cannot seem to find much out there on this topic.
