Granularity Level

• CURIE: gmeow:GranularityLevel

• Category: class
• Defined by: gmeow:slices/kernel
• Box roles: TBox role (What is this?)

A level of detail / resolution at which a value is expressed — a point on an open, ordered, domain-general axis (spatial: point ≺ address ≺ city ≺ region ≺ country; temporal: day ≺ month ≺ year ≺ decade ≺ century). The explicit facet behind 'no silent precision', and the axis that gmeow:coarsenTo generalizes along. Levels are individuals (never per-level subclasses), ordered by gmeow:coarserThan and aligned to external resolution vocabularies (OWL-Time time:TemporalUnit, ISO 19112 LocationType) by skos:exactMatch.

Structure

Subclass of: gufo:QualityValue

Practical Pattern

Use gmeow:GranularityLevel 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 when minting a point on a resolution ladder — a spatial or temporal level that a value can declare via gmeow:hasGranularity or coarsen toward via gmeow:coarsenTo.

Avoid when

• Avoid creating per-level subclasses (levels are individuals) and avoid using it for ordinary quantity values; a granularity level is a resolution, not a measurement.

How to use

• Mint each level as an individual, order it with gmeow:coarserThan, and anchor it to an external resolution vocabulary with skos:exactMatch; seed domain ladders in their own slices (spatial in places, temporal in temporal).

Examples

• ex:cityLevel a gmeow:GranularityLevel; gmeow:coarserThan ex:addressLevel.
