quality dimension

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

The quality dimension under which this assessment is made. Non-functional: a single assessment may cover several dimensions (e.g. a report that evaluates both positional accuracy and completeness), and competing dimension classifications coexist rather than collapse (Principle 9).

Structure

Property shape: object property; gmeow:QualityAssessment -> gmeow:QualityDimension

Practical Pattern

Use gmeow:qualityDimension from gmeow:QualityAssessment to gmeow:QualityDimension when the relationship itself belongs in the native GMEOW graph.

# Worked example: data quality IS a measurement. A gmeow:QualityAssessment
# is a gmeow:Observation subclass, so a completeness assessment carries the SAME
# bundle as any other measurement: gmeow:assessedEntity (the feature, a sub-
# property of observedFeature), a gmeow:qualityDimension naming WHICH quality, a
# gmeow:observationMethod, a gmeow:vantage (who assessed), and an entity-valued
# gmeow:ScalarQuantity result (98.5% with its unit) rather than a bare number.
# Quality is not a special boolean flag — it is an observation like temperature.

Usage Advice

Use when

• Use on a QualityAssessment to name the ISO 19157 dimension(s) it evaluates — positional, temporal, or thematic accuracy, completeness, consistency, or lineage.

Avoid when

• Avoid minting a new dimension class for an unlisted axis (add a gmeow:QualityDimension individual instead) and avoid forcing a single dimension when an assessment genuinely spans several — keep it non-functional.

How to use

• Point gmeow:qualityDimension at one or more gmeow:QualityDimension individuals; multiple dimensions on one assessment coexist, matching a report that grades several axes at once.

• ex:posAcc gmeow:qualityDimension gmeow:qualityDimensionCompleteness.
