A reference system (such as a coordinate system, datum, grid, or platform space) relative to which locations, coordinates, or measurements are expressed.

Structure

Subclass of: gmeow:Entity, gufo:Object

Practical Pattern

Use gmeow:ReferenceFrame 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 any reference system — coordinate system, datum, grid, or platform space — relative to which coordinates and measurements are expressed (Principle 11).

Avoid when

• Avoid embedding a frame inside a coordinate literal and avoid a frame instance where a coordinate value belongs; the frame is the system, not the position.

How to use

• Mint a ReferenceFrame, set gmeow:frameRealm / gmeow:frameKind / gmeow:hasMetricKind, nest it via gmeow:parentFrame, and point coordinate values at it via gmeow:hasReferenceFrame.

Examples

• ex:siteGrid a gmeow:ReferenceFrame; gmeow:frameRealm gmeow:frameRealmTerrestrial; gmeow:frameKind gmeow:frameKindGrid.
