Re: [OSM-dev] what server next?
Hi 2009/9/8 Frederik Ramm frede...@remote.org Your idea suffers from the fundamental problem that it only counts those having last touched an object. No, it doesn't. I thought of a mechanism to avoid that: Users adding ways/pois get a score of 3 per way/poi added, users adding more tags to existing way/pois get a score-point of 1 for each edit. Import sources get a 0.1 score-point per way/poi. One could also think of more sophisticated factors to calculate score-points. - initial creation: 3 score-point factor - adding name: 2 - adding other tag: 1 - import sources: 0.1 - mass changes: 0.1 / change - bots: 0 What about a limit for score-point gaining per hour/day for a user? * Of course, the score-point factors are subject to fine-tuning! They must be adjusted, when one creates such a solution. Regards Micha ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

2009/9/8 Grant Slater openstreet...@firefishy.com What is next? What are we going to need next? Last night I dreamed about a solution to the cc-by-sa attribution problem. It would be soo nice to have appropriate attribution displayed in OpenLayer while browsing the map. There it goes.. A server calculates user contribution for sets of 3x3 tiles (supertiles) for each zoom level 12-18. The calculation is done once a week (maybe done by t...@h clients). Users adding ways/pois get a score of 3 per way/poi added, users adding more tags to existing way/pois get a score-point of 1 for each edit. Import sources get a 0.1 score-point per way/poi. Score-points get calculated per supertile, top 4 contributors for each supertile including their score-points get stored in a database, the attribution-db. Keys and indexes on zoom level and new supertile index (maybe central tile x/y). OpenLayer gets extended in a way that while requesting tiles an additional request to the attribution-db is issued, contributors for the corresponding supertile get loaded and nicely presented in the lower right corner of the view. OSM runs the attribution-db and spreads the extended OpenLayer lib. * Information which user created a way is only available in history, so initial calculation is heavy-load, but must only be done once. * attribution information for mutliple supertiles could be aggregated into attribution-pages which are stored in the attribution-db. this attribution-pages are sent to the client, which sorts out the appropriate attribution with some .js magic for the current displayed view. This could save the attribution-db from load. * attribution score-point changes could be calculated on-the-fly, once an initial load of the attribution-db is done. :D Need more sleep, now.

2009/9/8 John Smith deltafoxtrot...@gmail.com Wouldn't this only serve to clutter things up and detract away from the important information? Nasa World Wind et. al. does a fine job in displaying copyright information without distract the experience. if they'd donate some decent kit in return for their logo being displayed etc. Wouldn't this only serve to clutter things up and detract away from the important information? :D Regards Micha ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Re: [OSM-dev] strange Osmosis/XML/...? problem yesterday
Hi, 2009/8/14 Frederik Ramm frede...@remote.org Hi, our automated job yesterday aborted with an out of memory condition in Osmosis. We traced this back to a change made to the node for Madrid (148332300) It's the node for spain (place = country) where someone added name:got with a lot of strange characters. That was me :D (name:got = ̷̴̹̰̰̓̀̽̾) For some reason, any time these characters pass through Osmosis, the size increases by a factor of four or so. I have created a simple test case replicating this: Will your tests pass with the original name:got value?
