Perhaps in some future version OSM will support a new object type, 'table of random whatever'. Then rows could be added for each species of tree, and individual trees could refer to a row of the table. This gets more into the realm of tagging all possible facts about the world, rather than just making a map of what's on the ground, but OSM has already gone some way in that direction.
In the meantime, duplicating the information on each object is probably the most convenient way for users. -- Ed Avis <e...@waniasset.com> _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
