Hi, Here are the properties of an example multipolygon: "You will also see that people are adjusting their own work to what is already there (because that's the "standard")" Well, I'm not sure. My humble experience shows that there are very thorough mappers who e.g. always add a "source"

More than about one third of Hungary has already been imported from the CLC dataset by others. The following tag is used for attribution: source=© EEA, Koppenhága (2009); Készítette a FÖMI a KvVM megbízásából (2009) I'm not a lawyer but I think this tagging is correct. see http://lists.openstreet
