Time Interval

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

A bounded stretch of time, optionally open-ended, delimited by a start and/or end instant.

Structure

Subclass of: gufo:AbstractIndividual

Practical Pattern

Use gmeow:TimeInterval 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 first-class bounded stretch of time that must itself bear properties — a frame, a granularity, Allen relations to other intervals, or the scope of a gmeow:TimeScopedRelation; the reify-on-demand sibling of the validFrom/validUntil statement-layer clocks.

Avoid when

• Avoid for a zero-duration point (use gmeow:Instant) and for the lightweight case where a statement merely holds over a period — there the RDF-star gmeow:validFrom/gmeow:validUntil clocks suffice without minting an interval.

How to use

• Bound it with gmeow:startedAtTime/gmeow:endedAtTime (xsd:dateTime, never xsd:date per P3) or gmeow:hasStartInstant/gmeow:hasEndInstant; declare its gmeow:hasTemporalFrame (P11) and any gmeow:hasGranularity, then attach Allen relations to peers.

Examples

• ex:tenureInterval a gmeow:TimeInterval; gmeow:startedAtTime "2019-03-01T00:00:00Z"^^xsd:dateTime; gmeow:hasTemporalFrame gmeow:temporalFrameUTCGregorian.
