- What is the real meaning of Q/P prefix -> Wikidata or Wikibase?
The intention was:
P and Q indicate the *type* of the entity ("P" = "Property", "Q" = "Item" for arcane reasons), "L" = Lexeme, "F" = Form, "S" = Sense, "M" = MediaInfo). As you can tell, we'd quickly run out of letters and cause confusion if this became configurable.
Using prefixes to indicate where the entity comes from is indeed useful and is already part of the model. The prefix for Wikidata is "wd:", wo "wd:Q12345" is an item from Wikidata. The prefix can be omitted for local entities, so Q12345 is an item on the local repo (or the default repo of a wikibase client).
