The start instant of a time interval.

Structure

Property shape: object property; gmeow:TimeInterval -> gmeow:Instant; functional

Practical Pattern

Use gmeow:hasStartInstant from gmeow:TimeInterval to gmeow:Instant when the relationship itself belongs in the native GMEOW graph.

Usage Advice

Use when

• Use to bound an interval's start with a full gmeow:Instant when that endpoint itself needs a frame, granularity, determinacy, or EDTF approximation — the reified counterpart of gmeow:startedAtTime.

Avoid when

• Avoid when a bare crisp dateTime suffices (use gmeow:startedAtTime inline) and avoid asserting two start instants (functional — at most one).

How to use

• Point the interval at a single gmeow:Instant carrying its own gmeow:instantValue/gmeow:edtfValue and frame; pair with gmeow:hasEndInstant, or omit it for an open interval.

Examples

• ex:tenureInterval gmeow:hasStartInstant ex:hireInstant.
