instant value

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

The crisp instant as an xsd:dateTime literal in the associated temporal frame.

Structure

Property shape: datatype property; gmeow:Instant -> xsd:dateTime; functional

Practical Pattern

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

Usage Advice

Use when

• Use to carry the crisp, machine-computable value of a gmeow:Instant — the single xsd:dateTime the solver and renderers read.

Avoid when

• Avoid for approximate, uncertain, or open-ended points (use gmeow:edtfValue) and avoid an xsd:date literal — base-triple time is xsd:dateTime (P3); functional, so an instant has at most one crisp value.

How to use

• Write a full xsd:dateTime interpreted in the instant's gmeow:inTemporalFrame; when the point is only known to a coarser resolution, set it to the canonical start of the period and record the real resolution with gmeow:hasGranularity.

Examples

• ex:birthInstant gmeow:instantValue "1804-07-12T00:00:00Z"^^xsd:dateTime.
