Lovely, welcome info forwarding, Marc. And congratulations !!!
Impressive but ouch, Marc #2, they use overpass, and extensively. If everybody were using their page much, overpass would soon be on their knees. I think that how to use POIs should be thought out before making them. It's great how a GPS uses a selection offline and how a Web display could do the same. But they use predetermined kinds of POIs that they selected as data they store locally. May I recall another approach that I presented as a way for OSM.be to make money. For each "customer" or usage, a POI list is built that contains the IDs of the OSM elements + icon URL. The server whose task is to display the map + POIs can fetch the list from any URL. http://server http://list node/way/area ID icon_URL ... For speed and to spare the sources, it can build a cache. Cheers André.
