Additional spatial relationships

[epaulson]

We have talked about adding some new relationships for spaces to better describe the topology of a space - things like Adjacency or connectivity. This has use cases in wayfinding and in reasoning about access control.

I guess as a first step I'd like just to be able to say that Space A connects to Space B.

It should be possible to say that a connection is accessible or not - maybe there's some formal definition of accessible that we could point at, e.g. something from the Americans with Disabilities Act - but as something informal, maybe "can a person using a wheelchair get from space A to space B using this connection" (sometimes they can't - the last office building I worked in was old and the entrance to room A had 3 stairs you needed to step down to get into it if you were entering from room B- the wheelchair route into room A if you were starting in room B was to take elevator1 in room B down one flight, cross through room C, and then take the elevator2 back up one flight from room C into room A)

@jbkoh has more use cases in mind

This is a good feature to have for a lot of reasons. It can be used for intelligent scheduling - say I am a facility manager and need to schedule a wrestling match in the gym and I also want to schedule adjacent areas for entrances and exits.

Decision taken at last REC Technical Committee meeting: REC members on the Brick-REC collaboration delegation are authorized to jointly with Brick implement design changes as needed to support this. Next call on that collaboration is scheduled for two weeks from now.

We discussed this again at the recent REC Technical Committee (TC) meeting. Based on our experiences we find this is a rather complex domain and the TC unfortunately dont have the resources to drive this as of now. Consequently marked as a feature request (enhancement) for future (4.1++) implementation. We'd be happy to receive a PR.

I'm late to this discussion, but would like to support this idea with a few use cases.

• I want to query the surgery prep room associated with a surgery room.
• I want to query adjacent gates in airports to manage traffic and monitor people movement.

For our cases, a simple definition like "isAdjacentTo" between Locations would be enough. We can worry about doors/walls/etc. later, imho.

Perhaps of note - the schema.org geo types: https://schema.org/GeospatialGeometry but they might (or at least, the RDFLIB folks are encouraging them to ) just use geoSPARQL properties in schemaorg/schemaorg#1375

(I think for accessibility properties like wheelchair-reachable you'd still probably need some properties that aren't in geosparql - schema.org has talked a bit about that too - schemaorg/schemaorg#254 )
