Sensory Observation

• CURIE: gmeow:SensoryObservation
• IRI: https://blackcatinformatics.ca/gmeow/SensoryObservation
• Category: class
• Defined by: gmeow:slices/observations
• Box roles: TBox role (What is this?)

An observation produced by a sensor or sensory apparatus reading a physical property of the environment. Specialises Observation with sensor-specific properties (sensory property, sensor platform, sampling feature).

Structure

Subclass of: gmeow:Observation

Practical Pattern

Use gmeow:SensoryObservation as a specialized kind of gmeow:Observation. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

# Worked example: a sensor reading on the observation stack . A
# gmeow:SensoryObservation records WHAT was sensed (gmeow:sensoryObservationOf),
# WHICH gmeow:ObservableProperty (humidity), and the gmeow:SensoryQuantity result.
# A gmeow:Sensor is a gufo functional complex that is also an Agent, so it is the
# observation's gmeow:vantage — the SensoryObservation is an Observation like any
# other, just produced by an instrument on a gmeow:SensorPlatform at a location.

Usage Advice

Use when

• Use when the observation is a reading taken by a sensor or sensory apparatus of a physical property of the environment — the form that travels in a gmeow:Stream and carries sensor/platform/sampling-feature detail.

Avoid when

• Avoid for a human judgement or a derived/computed value (use gmeow:Measurement with the matching gmeow:observationType) and for a standpoint assertion (gmeow:StandpointClaim); this kind is specifically instrument-mediated sensing.

How to use

• Type the reading gmeow:SensoryObservation, put the sensor or platform in gmeow:vantage (or gmeow:streamSensor / gmeow:streamPlatform when streamed), and attach the value as a gmeow:ScalarQuantity result; group time-ordered readings under a gmeow:Stream.

Examples
