- Category: class

The kind of a named period (geologic eon, era, period, epoch, age; historical dynasty, era; fiscal year). A value, never a subclass.
Structure
Subclass of: gufo:QualityValue
Practical Pattern
Use gmeow:PeriodType as a specialized kind of gufo:QualityValue. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.
Usage Advice
Use when
- Use as the value vocabulary for classifying a
gmeow:NamedPeriodby its defining domain — geologic rank, historical kind, fiscal kind — referenced throughgmeow:periodType.
Avoid when
- Avoid modelling a period kind as a subclass of
gmeow:NamedPeriod(kinds are individuals) and avoid using it for the period's bounds; the type names the category, not the extent.
How to use
- Reference a seeded
gmeow:PeriodTypeindividual from a period viagmeow:periodType; align it to an external authority (ICS geologic ranks) with skos:exactMatch in the mapping DSL, and mint new individuals rather than subclasses.
