My original idea was only about tags but it could be extended to geometries of course - as i sketched in my reply to Martin, which would essentially mean creating a copy for the building a bot orthogonalizes if the building already has a manual building=yes tag. If the bot only changes the tag the building would remain a normal hand mapped geometry but would get a bot:building=yes in addition to the building=YES. Of course duplicating geometry data would make it much more difficult for data users to make decisions about selectively using data and it would make it much more difficult for editors to allow mappers to edit the data correctly. This is why i originally suggested this only for tags - after all the vast majority of bot edits are tag modifications only, geometry edits by bots are technically much more complicated to do right so they happen less frequently. As already said - if this approach is not considered favorably it is always possible to use the other method and forbid bots to touch anything with a bot=no tag and thereby allow mappers to opt out of bot edits on a case-by-case basis. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
