Lost mappers project (if anything):

Simon will produce a wrap up in a couple of days. About 12 larger mappers have agreed recently as a result of the campaign.

6. Technical Rebuild

Progress and issues

http://www.osmfoundation.org/wiki/License/Rebuild_Plan

Test code being finalised.

Visualization tools looking forward. We will leave it to the community to come up with something if required, our feeling is that the need is minimal.

Tile cache … since it takes time to refresh some tiles will come from a CC-BY-SA db and some from an ODbL, although all tiles will be licensed CC-BY-SA. Is this an issue in terms of how they should be attributed?  LWG does not see any need to speed up expiry of old cache. When people see “Copyright OpenStreetMap”, or “©OpenStreetMap” with or without other details, and want more details, they will come to OpenStreetMap website … we need to make sure that http://www.openstreetmap.org/copyright page adequately describes a) the copyright of tiles made by us, and b) where they come from, i.e a CC-BY-SA database and/or a an ODbL database.

7. Hall of Shame

Apple - We understand from legal counsel that our first step should be to follow Apple’s formal DMCA take-down notice procedure at http://www.apple.com/legal/contact/ We will draft this notice and inform the board that we want to send it immediately. The board is taking this over as per their Extraordinary Meeting minutes 7th April.

Microsoft - At the beginning of the year, German mappers noticed that Bing has been blurring aerial imagery of military sites based on OSM polygons ... this raises share-alike derivation issues. We understand that Microsoft have since apologised in an official press release and will use alternative sources but has not yet begun to do so.  This issue has been causing some concern in the OSM community. We will gather more information and consider whether we need to take further information. Simon will take the lead on this.
