Hi, Thanks for the responses. Pe sâmbătă, 9 mai 2020, Marius Hoch <hoo(a)online.de> a scris: Other things that I have seen done in modules throughout the ecosystem are using the bbox limits (P1333&co) and the surface. I am also considering using the geo data from Commons, although that's in pretty bad shape (pun intended). The precision is indeed another solution, although I would leave it as the last option, since it depends more often on the data source than on the subject itself. I hope some of those can be reused in php as well. Any suggestions on how to prioritize those and/or other data sources in Lua are welcome. I asked about the php code as I thought you might have some "instance of"-based algorithm I could replicate. Straini
