Constraint Operator

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

The comparison operator of an atomic constraint — the ODRL operator vocabulary (eq, neq, lt, lteq, gt, gteq, isPartOf, isA, isAnyOf, …).

Structure

Subclass of: gufo:QualityValue

Practical Pattern

Use gmeow:ConstraintOperator 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 the comparison-operator axis — the ODRL operator (eq, lteq, isAnyOf, …) an atomic constraint applies, referenced via gmeow:constraintOperator.

Avoid when

• Avoid minting per-operator subclasses (operators are individuals, Principle 9) and avoid inventing operators beyond the ODRL set; reference a seeded value.

How to use

• Reference a seeded value (gmeow:operatorEq, gmeow:operatorLteq, …) from gmeow:constraintOperator; the set tracks the ODRL operator vocabulary.

Examples

• ex:opLteq a gmeow:ConstraintOperator; rdfs:label "less than or equal to"@en.
