Instant

• CURIE: gmeow:Instant
• IRI: https://blackcatinformatics.ca/gmeow/Instant
• Category: class
• Defined by: gmeow:slices/temporal
• Box roles: TBox role (What is this?)

A zero-duration point in time, distinct from a TimeInterval. Carries a crisp instantValue (xsd:dateTime) and/or an edtfValue (EDTF literal) relative to a TemporalFrame.

Structure

Subclass of: gufo:AbstractIndividual

Practical Pattern

Use gmeow:Instant as a specialized kind of gufo:AbstractIndividual. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Usage Advice

Use when

• Use for a zero-duration point that must itself bear a frame, a granularity, a determinacy, or an EDTF approximation — the reified point that a gmeow:TimeInterval endpoint or a gmeow:NamedPeriod boundary references.

Avoid when

• Avoid for an inline timestamp that needs no facets (use gmeow:atTime or gmeow:startedAtTime) and for a bounded span (use gmeow:TimeInterval); an Instant is the heavyweight, facet-bearing point.

How to use

• Give it a crisp gmeow:instantValue (xsd:dateTime, P3) and/or an approximate gmeow:edtfValue, declare its gmeow:inTemporalFrame (P11), and attach gmeow:hasGranularity / gmeow:hasDeterminacy when the resolution or determinacy is below crisp-to-the-second.

Examples

• ex:birthInstant a gmeow:Instant; gmeow:instantValue "1804-07-12T00:00:00Z"^^xsd:dateTime; gmeow:inTemporalFrame gmeow:temporalFrameUTCGregorian; gmeow:hasGranularity gmeow:granularityDay.
