5. Technical Rebuild

Management group met Wednesday and mildly favours "continuous changeover" model on non-technical grounds.

The Rebuild group held a conference call Sunday. Consensus exists that an in-place schema update of the existing database is the best approach. There is also a generally positive attitude to the idea of "continuous changeover", though some more details need to be discussed.

V0 principle: The LWG was asked by the Rebuild group to join with them in endorsing the principle that V1 objects by non-agreeing mappers should not automatically be deemed tainted - that is, that the very existence as an object should not enjoy copyright protection. Rather, only co-ordinates and tags added by the non-agreeing mapper will be deemed tainted. In this way, V1 objects will be treated in the same way as subsequent versions. The LWG discussed this principle and is pleased to endorse it.

Last CC-BY-SA Planet file: Again arising from a request from the Rebuild group, LWG is requested to consider the long-standing published policy of publishing one last CC-BY-SA planet file immediately prior to the licence cutover. Since one of the options under consideration by the Rebuild group is to begin the process of redacting data even before April. This could be seen as having an impact on some of the goals in publishing a last CC planet file. It was noted too, both by Rebuild and LWG, that the ongoing remapping efforts also have the potential to impact the same goals (since some remapping effort is known to be by the “scorched earth” method of deleting first, then slowly remapping). No firm view has yet been taken on this matter.

Mike to draft messaging required for consumers of planet diffs related to changeover requirements due to licence change. This will include a proposed new attribution for tiles.

6. OSM Poland

Mike has written to UMP. Responses received indicate that the UMP community would be willing to let OSM continue to use UMP data under ODbL under certain conditions. Mike to follow up with these discussions during this week.

AOB
