Hi Woodpeck. Can you point me to where these "foreign keys" are? I believe I only added very standard keys (address, phone, website, various names), and "ref" for the hotel reference code. Under what key do you think that info would fit better? The community discussion for this import is here, as linked in the wiki page in the changeset tags: https://community.openstreetmap.org/t/proposed-import-of-all-the-places-data-onto-existing-hotel-pois-in-the-us/109552 . Thanks!
