Observable Property

A physical, chemical, biological, or environmental property that can be observed or measured by a sensor. A value vocabulary (individuals, never subclasses) so any new property — from temperature to neural activation to social sentiment — is a new individual, not a new class (Principle 9).

Structure

Subclass of: gufo:QualityValue

Practical Pattern

Use gmeow:ObservableProperty as a specialized kind of gufo:QualityValue. 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.
