A source as the management API shows it: keys masked.
object
Left empty on create: made from the name.
buildinglinks (the Buildinglinks protocol) or generic.
A path that says whether the system is up, e.g. health; the system
test asks it with the system’s key.
Its koppelingen: the object ids (e.g. nl.bag.pand.0014100040022681)
this system serves.
The binding of a dataset onto an internal API: where the data plane sends a request, with which key, and what it lets through.
object
The address of the system, e.g. https://bms.example.nl/api.
The header that carries the key, e.g. X-Api-Key.
The key; shown as ••••••, and sent back as such it stays as it was.
Methods the data plane lets through, e.g. ["GET"] for reading or
["GET", "POST", "PATCH"] for reading and steering. At least one: an
empty list lets nothing through.
Path patterns the data plane lets through (* one segment, ** the
rest), e.g. api/sites/4711/**, or ["**"] for the whole API. At
least one, except on a Buildinglinks system, whose koppelingen fill
them (v1/buildings/{object}/**): an empty list lets nothing through.
Koppelingen that differ from the default, per object (decisions #72): the data plane routes the building to the system’s own id and key.
object
How one object is reached in a system (decisions #72).
object
The system’s own id of the building; the default is the object id.
A key for this building only; the default is the system’s.
What the system provides for this building: data (the default),
topology (the indeling, decisions #71) or both.
Its koppelingen that differ from the default: every object is one; this lists only the ones with an own id or key, or that provide more or other than data (decisions #72).
A koppeling as the API shows it: the object, and how it differs.
object
The system’s own id of the building; the default is the object id.
A key for this building only; the default is the system’s.
What the system provides for this building: data (the default),
topology (the indeling, decisions #71) or both.
The object id, e.g. nl.bag.pand.0014100040022681.
Single source only: the products that come from it.
