coordinate frame

• CURIE: gmeow:coordinateFrame
• IRI: https://blackcatinformatics.ca/gmeow/coordinateFrame
• Category: property
• Defined by: gmeow:slices/places
• Box roles: RBox role (What is this?)

Relates a set of coordinates to the reference frame they are expressed in.

Structure

Property shape: object property; gmeow:SpatialCoordinates -> gmeow:ReferenceFrame; functional Sub-property of: gmeow:hasReferenceFrame

Practical Pattern

Use gmeow:coordinateFrame from gmeow:SpatialCoordinates to gmeow:ReferenceFrame when the relationship itself belongs in the native GMEOW graph.

Common Companion Terms

gmeow:hasReferenceFrame, gmeow:SpatialCoordinates, gmeow:ReferenceFrame

Usage Advice

Use when

• Use to declare the single frame a SpatialCoordinates value is expressed in; functional, a subproperty of gmeow:hasReferenceFrame.

Avoid when

• Avoid omitting it (the frame gate warns) and avoid using it outside SpatialCoordinates.

How to use

• Set one gmeow:coordinateFrame per SpatialCoordinates; for celestial points use it on CelestialCoordinates too.

Examples

• ex:pos gmeow:coordinateFrame gmeow:referenceFrameWGS84.
