Do you have guidelines or suggestions how to handle these tags when modifying the objects, e.g. splitting them into several objects? Shall all new objects contain these IDs then? > In addition, Is see absolutely no value in a bot going around dropping > tags just for the sake of dropping tags. > > Any gain in the reduction of the size of the DB will be accompanied by > a larger increase of the size of the history by this bot going around > modifying thousands of objects. I understand this point of view and share it partially, but on the other hand it is very confusing for new mappers (and in general also to the experienced) to see a lot of tags whose meaning is only clear from looking at third party documentation. Long tag lists of non-osm-tags (i.e. references to external datasets) will also raise the chance that the missing of important osm-tags (like main tags for classification) are overlooked. And as you point it out, deleting these third party ids would still keep them in the history so anybody willing to do a conflation of updated data can rely on this information. cheers, Martin
