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

The original date/time of the occurrence being excepted — the instance that would have been generated by the recurrence rule.

Structure

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

Practical Pattern

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

Common Companion Terms

gmeow:ScheduleException

Usage Advice

Use when

• Use to identify WHICH generated occurrence an exception overrides, by the date/time the recurrence rule would have produced — the RFC 5545 RECURRENCE-ID anchor.

Avoid when

• Avoid recording the new time here (that is the replacement event's own placement) and avoid an xsd:date literal — base-triple time is xsd:dateTime (P3); functional, so one anchor date per exception.

How to use

• Write the full xsd:dateTime the rule would have generated, in the schedule's time zone; pair with gmeow:exceptionReplacementEvent when the occurrence is moved rather than cancelled.

Examples

• ex:standupSkip gmeow:exceptionOriginalDate "2026-06-19T09:00:00Z"^^xsd:dateTime.
