Wouldn't this problem be easier to manage if each CC-BY data source was kept in separate data store which is combined as a layer on the client or tile server? These layers could then be attributed when or if they are actually shown. This would also simplify the situation where data such as the postcode boundaries is being attributed to the ABS but has been changed by an OSM mapper, possibly not for the better, as well as allowing us to easily incorporate updates.

There was a issue being explored about the fact that the Contributor Terms (rather than ODbL itself) allowed relicencing but didn't explicitly ensure that attribution was maintained: http://wiki.openstreetmap.org/wiki/Open_Database_License/Contributor_Terms/Open_Issues#Incompatibility_with_CC-BY_.2F_Attribution_Data Attribution is a big thing to comply with the spirit of the government data releases but the respondent on that wiki page states "Should a data donor feel that this [attribution on derived works] is important, then probably that data should not be in OSM, no matter what license we use.". This seems out of touch with the situation on the ground; one of the big things any data donor is going to get out of providing their data is free advertising for how public minded they are. I would think the better solution is to have the attribution simplified like Google Maps does. eg. Google Maps for canberra says "Copyright PSMA, MapQuest" etc. OSM post-ODbL could have a technical solution that suggests to derivative users (Mapnik etc.) if you want to make a map of data between -35.15, 149.00 and -35.3, 149.25, it should have "Source: OSM Contributors, ABS, Geoscience Australia" on it. In the case of Australia, we also have stuff like the Service Stations and I don't know the attribution requirements on those but I'm sure that there aren't so many data imports that there would be difficulty attributing them when they are visible. ie. The ABS suburbs aren't visible on a world map but the UN coastline boundaries are so give credit where credit is due. _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
