• Category: property
• Defined by: gmeow:slices/temporal
• Box roles: RBox role (What is this?)

The reference position of a temporal frame, when one is needed. Optional: TAI needs none; civil time needs a timezone.

Structure

Property shape: object property; gmeow:TemporalFrame -> gmeow:ReferencePosition; functional

Practical Pattern

Use gmeow:frameReferencePosition from gmeow:TemporalFrame to gmeow:ReferencePosition when the relationship itself belongs in the native GMEOW graph.

Common Companion Terms

gmeow:TemporalFrame, gmeow:ReferencePosition

Usage Advice

Use when

• Use to wire a frame to the place its time depends on — a timezone for civil offset, an observatory for sidereal time, a planet for an off-Earth calendar.

Avoid when

• Avoid on position-independent frames (TAI, TT, zero-offset UTC) and avoid asserting two positions (functional — at most one per frame).

How to use

• Set at most one gmeow:ReferencePosition individual; leave it absent where the scale alone fixes the time, since the property is optional.

Examples

• ex:myFrame gmeow:frameReferencePosition ex:torontoTZ.
