Protocols

Protocols the ontology models as they are, and how their entities are linked to Things, Places and Points. Others, including Modbus, KNX and C-Bus, map directly to the ontology's classes: see Mapped Connectors.

📄️BACnet

The eleven BACnet object classes, how a BACnet device and its objects link to Things and Points, and a starting map from object types to Brick point classes.

📄️OPC UA

The OPC UA classes, how a server's address space is stored as Objects and Variables, how they link to Things and Points, and the signals that map a Variable to a Brick point class.

📄️OpenUSD

The dtmi:mapped:openusd classes — representations, analytic shapes, prim bindings, layers, level-of-detail heuristics and spatial constraints — and how a Thing or Place gets 3D geometry.
