Hi folks,
it's been a long time coming, but we're finally gearing up for putting some development effort into an OSM tileservice running in production to serve Wikimedia sites. This is being driven by the mobile team but obviously has lots of non-mobile use cases as well, including the recent Wikivoyage addition to the Wikimedia familiy. This work will probably not kick off before January/February 2013; before then, the mobile team is working to finish up the GeoData extension ( https://www.mediawiki.org/wiki/Extension:Geodata ).
To get broader community involvement and sync up with existing volunteer efforts in this area, it'd IMO be useful to plan a face-to-face meetup/hackfest just focused on geodata/mapping related development work sometime around Feb/March 2013.
WMF is not going to organize this, but we can help sponsor travel and bring the key developers from our side who will work on this. Are there any takers for supporting a 20-30 people development event in Europe focused on mapping/geodata? I'm suggesting Europe because I know quite a few of the relevant folks are there, but am open to other options as well.
Cheers, Erik
