Model a building data point and its unit of measure in Brick

Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Declare the point as an instance of the most specific applicable Point subclass — Sensor, Setpoint, Alarm, Command, Parameter, or Status — e.g. "mybldg:t1 a brick:Air_Temperature_Sensor"
Relate the point to equipment/location context with brick:isPointOf (or the inverse brick:hasPoint) rather than assigning a location directly to the point
Attach a QUDT unit with brick:hasUnit pointing to a unit: URI, e.g. unit:DEG_F
Validate candidate units for a point type with a SPARQL query over brick:measures/qudt:applicableUnit
Known gotchas
Points cannot have a direct location relationship — associate the point with equipment, then place the equipment in a location
hasUnit values must come from the QUDT unit vocabulary; free-text unit strings won't validate or federate with other Brick tooling
