Authorizations
Section titled “Authorizations”Parameters
Section titled “Parameters”Path Parameters
Section titled “Path Parameters”The connection (abonnement) to call through, as Verbindingen in the connector names it.
Object id of the building: the register identification in dotted form, for example nl.bag.pand.0014100040022681.
The object id of the building: its register identification in dotted form, e.g. nl.bag.pand.0014100040022681.
Query Parameters
Section titled “Query Parameters”Only these points, and only the locations they are in with everything above them. A comma-separated list (a,b) or the parameter repeated; at least one id.
Responses
Section titled “Responses”The layout.
Response of GET /v1/buildings/{building_id}/topology (profile https://w3id.org/buildinglinks/v1/topology, decision #71): the locations of the building and where each point is. Point ids are those of the source. With point_ids only those points, and only the locations they are in with everything above them (part_of).
object
Protocol version, carried by every response.
Object id of the building: the register identification in dotted form, for example nl.bag.pand.0014100040022681.
V2 draft: a place in the building (the building, a level, a room or a zone). Classes come from RealEstateCore, for example rec:Building, rec:Level, rec:Room, rec:Zone and rec:HVACZone.
object
Id of a location returned with include=locations (v2 draft).
RealEstateCore (rec:) or Brick location class.
The enclosing location; absent for the building itself.
object
Stable address of a point, for example 9b41d0aa.
Id of a location returned with include=locations (v2 draft).
