Mapping the Mappings. Networking the Networks.
As we see now, the Meta-Mapping of Mapping projects is crucial for easing out redundancies in our work : because in the beginning you have the impression you are following a great idea no one else has been thinking about, but once you get out there, you see there are already many resources available to build upon.
Additionally, it's kind of important to connect all those activists within the field of visualizing the autonomous society (as @Pavlik might say).
So MMM will not only focus on the Taxonomy for entering this data into OpenStreetMap (OSM), but also on connecting the different mapping activities and providing an additional metadata layer for OSM so one can easily add "profiles" to items. Still authentication remains an issue.
