event time

• CURIE: gmeow:eventTime
• IRI: https://blackcatinformatics.ca/gmeow/eventTime
• Category: property
• Defined by: gmeow:slices/events
• Box roles: RBox role (What is this?)

The instant at which a point-like event occurred (xsd:dateTime — DL-clean, never xsd:date). Replaces the former free-text gmeow:eventDate. Non-functional: competing standpoint-indexed dates coexist as confidence-weighted statements.

Structure

Property shape: datatype property; gmeow:Event -> xsd:dateTime

Practical Pattern

Use gmeow:eventTime from gmeow:Event to xsd:dateTime when the relationship itself belongs in the native GMEOW graph.

Usage Advice

Use when

• Use for the instant of a point-like event whose date is known crisply — a birth time, a commit timestamp; the DL-clean replacement for the retired free-text gmeow:eventDate.

Avoid when

• Avoid xsd:date literals (Principle 3 — always xsd:dateTime), avoid it for a spanning event (use gmeow:eventInterval) or a fuzzy date (use gmeow:earliestStart / gmeow:latestEnd), and never collapse competing dates — keep it non-functional.

How to use

• Assert an xsd:dateTime literal; carry a disputed date on its own statement with gmeow:accordingTo + gmeow:confidence, and a non-default calendar on gmeow:eventTemporalFrame.

Examples

• ex:birth gmeow:eventTime "1947-06-14T09:30:00Z"^^xsd:dateTime.
