- Category: property
- Defined by:
gmeow:slices/places - Box roles: RBox role (What is this?)
The geometric centroid of a place — a flat shortcut for the common case. The full relator form is a SpatialAggregation with aggregationFunction aggCentroid, carrying provenance, frame, and solver reference.
Structure
Property shape: object property; gmeow:Place -> gmeow:Geometry
Practical Pattern
Use gmeow:hasCentroid from gmeow:Place to gmeow:Geometry when the relationship itself belongs in the native GMEOW graph.

Usage Advice
Use when
- Use as the flat shortcut for a place's geometric centroid.
Avoid when
- Avoid it when provenance, frame, or the aggregation method matter — promote to a

How to use
- Use flat
gmeow:hasCentroidfor the common case; the full form carries frame and solver reference.
