nostr:npub1m6wa2hzdt80n7pa3pqatwl8802qcjyv9l7fg00vv2feq0dg8kjwsq42jfw thanks. When we wrote that page - 6 years ago - there wasn't support for memorial benches on OSM.

We are working with them to make it easier to ingest our data. Not sure what you mean by "compatible" though - it's just a standard GeoJSON file.
