gmeow:slices/places - Box roles: RBox role (What is this?)
A Well-Known Text (WKT) serialization of a geometry. The range is rdfs:Literal (not geo:wktLiteral) to stay within the OWL 2 DL datatype map; data may still tag the literal ^^geo:wktLiteral, and the alignment to geo:asWKT preserves GeoSPARQL semantics for spatial engines.
Structure
Property shape: datatype property; gmeow:Geometry -> rdfs:Literal
Practical Pattern
Use gmeow:asWKT from gmeow:Geometry to rdfs:Literal when the relationship itself belongs in the native GMEOW graph.

Usage Advice
Use when
- Use to carry a Well-Known Text serialization of a geometry; aligns to geo:asWKT for spatial engines.
Avoid when
- Avoid typing the range as geo:wktLiteral in the core (kept rdfs:Literal for OWL 2 DL) and avoid duplicating the same shape as both WKT and GeoJSON when one suffices.
How to use
- Put
gmeow:asWKTon aGeometry; data may tag the literal ^^geo:wktLiteral, andgmeow:geometryTyperecords its structural kind.
Examples
- ex:shape
gmeow:asWKT"POLYGON((-3.2 55.9,...))".
