What is prefixed by osmm: osmt: and other osm_: ?

These prefixes can be found everywhere in examples, but they are not listed here.

They are the prefixes from the OpenStreetMap (OSM) Data Model which are necessary for querying the OSM SPARQL Endpoint at https://sophox.org

 "OSM Data":{
      "osmnode":"https://www.openstreetmap.org/node/",
      "osmway":"https://www.openstreetmap.org/way/",
      "osmrel":"https://www.openstreetmap.org/relation/",
      "osmt":"https://wiki.openstreetmap.org/wiki/Key:",
      "osmm":"https://www.openstreetmap.org/meta/",
      "pageviews":"https://dumps.wikimedia.org/other/pageviews/"
 }

All other osm* prefixes are the Sophox prefixes for its Wikibase instance, corresponding to the same concepts of Wikidata that start with 'w' , e.g.

PREFIX osmd: <http://wiki.openstreetmap.org/entity/>

analog to

PREFIX wd: <http://www.wikidata.org/entity/>"

Same for all of the other prefixes like

PREFIX osmdt: <http://wiki.openstreetmap.org/prop/direct/>

etc. I hope this helps.
