Physical Object
- CURIE:
gmeow:PhysicalObject - IRI: https://blackcatinformatics.ca/gmeow/PhysicalObject
- Category: class
- Defined by:
gmeow:slices/kernel - Box roles: TBox role (What is this?)
An entity that is a material thing occupying space and time — a device, instrument, vehicle, building, or natural body. Distinct from Agent (which acts and bears responsibility) and InformationObject (which carries information content). The sortal for pose-bearing, sensor-hosting, and spatially-located things that are not agents.
Structure
Subclass of: gmeow:Entity, gufo:Object
Practical Pattern
Use gmeow:PhysicalObject as a specialized kind of gmeow:Entity, gufo:Object. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Usage Advice
Use when
- Use for a material thing that occupies space and time and is not itself an agent — a device, instrument, vehicle, building, sensor host, or natural body that bears a pose or a spatial location.
Avoid when
- Avoid for acting participants (
Agent), for content carriers whose materiality is incidental (InformationObject), and for convention-sustained things (SocialObject); the three are disjoint withPhysicalObjectby design.
How to use
- Type the artifact as
PhysicalObjectand hang pose, sensor, and spatial-location relations on it; keep agency and information roles on separate co-located entities rather than overloading the physical sortal.
Examples
- ex:rover a
gmeow:PhysicalObject;gmeow:hasPoseex:roverPose.
