I recently have been surprised to see there are not too many solutions at all discussing the best methods of versioning datastores which are made available for editing.
I am looking for a robust, efficient solution which would me to share a bunch of data with registered users and where those users can edit this geodata or associating attributes individually. My requirement though is that I need any and all edits logged so they can be rolled back to any previous state just like a wiki.
More specifically, I am utilizing a tool called CartoDB.com (built on PostGIS 2.0) through which whatever method needs to be compatible.
Very curious to learn any/all information you guys might be able to share in regards to my needs. Thanks - CH
