Well, in order to ensure data integrity, with the relationships we have, a place is:
- A single physical structure (probably without any major renovations), under a single owner, probably only for a single "branding". You could call that "place == establishment", I suppose.
I think we currently use "place" for two different concepts:
- A physical structure
- An organization
When we talk about the place some music was recorded at, we care about the physical structure: the acoustics of that brick, steel, wood, etc. affect the recording; its size and shape affect the placement of musicians, etc. We put in different places for different rooms in the same building. If a recording studio moved down the street, that is clearly a new place: it could have different acoustics, a different size/shape, etc. Same if the building burnt down and was replaced, or even majorly remodeled.
But then we also have the various engineering relationships (mixed at, edited at, engineered at, mastered at). Often those (especially mastered) are the name of a large company—and we don't really know what physical space it was done in (we sometimes know the building, though not the room). The sound produced is from the people doing it (a different relationship) and the equipment being used (AFAIK, we don't store that), not the room it was done in.
We have a URL for a place's blog & social network accounts (clearly, actually the organization, and why only a single "branding"); we have who founded an place (again, an organization—buildings do not even have founders); we have relationships for where an engineer works (which could be both—but I've never seen a building sign a paycheck).
Finally, very clearly an organization, we have the "place commissioned work" relationship.
I think we ought to find a way to separate out the two concepts, and just use place for ①, not ②. Organizations own, occupy, or use places; etc. That might require a schema change—or maybe we could just have two "types" of places, and add a few place-place relations. Not sure...
BTW: Address and coordinates (at least, unless the coordinates are really precise, and our coordinates lack altitude) do not let you link two uses of a place—remember that a place can be just a room, not an entire building. That seems to argue for a place-place relationship for that.
