Possibly not of global relevance (yet), but since it is my home town I thought I’d give it a quick shout-out:
Earlier today, Offenes Köln (Open Cologne) was officially announced. It’s a grassroots project by Marian Steinbach in Cologne, Germany that aims to make information, documents and data related to local government available (and accessible) to the general public by way of aggregating, enhancing and presenting government information
from various sources from the “Ratsinformationssystem” (city council information system), the official platform of the City of Cologne.
Open Cologne appears to have been inspired by Frankfurt Gestalten, whose creator Christian Kreutz I interviewed a while back.
