some point you decide to add some new area of data, e.g. biological, you could add new prefixes for that too, but that would also be a "separate" project.
The Q, P, L, M, etc are used to identify the *type* of entity. They are not for keeping projects separate. That was never their purpose. Wikibase uses prefixes before that, but they are prefixed *before* the letter that indicates the type.
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).I think that was a big mistake -- the "(or the default repo of a wikibase client)" -- because wd implies Wikidata, not Wikibase, so it dilutes the meaning of "wd:". See my other email on how I fixed it.
I'm confused - yes, we: should ALWAYS imply wikidata. Your wikibase instance would have its own prefix (that can be omitted for local use), e.g. "osm:".
For the record, I'm just voicing my oppinion here, and telling you what the original intention was. I'm no longer working on Wikidata or Wikibase, and I can't make any decisions on any of this.
