Quantity

• CURIE: gmeow:Quantity
• IRI: https://blackcatinformatics.ca/gmeow/Quantity
• Category: class
• Defined by: gmeow:slices/observations
• Box roles: TBox role (What is this?)

A universal scalar numeric value bundled with unit/frame, determinacy, and provenance — the synthesis of FRAME-GEN + DET-GEN + OBS (ScalarQuantity alias precedent). Equivalent to gmeow:ScalarQuantity; the domain-neutral name for the same construct. Used for temperatures, distances, counts, probabilities, masses, prices, and any other quantitative observation result. The value lives in gmeow:quantityValue; the unit/frame in gmeow:hasUnit / gmeow:hasReferenceFrame; the determinacy in gmeow:hasDeterminacy; the provenance in gmeow:isResultOf.

Structure

Subclass of: gmeow:Entity, gufo:Object

Practical Pattern

Use gmeow:Quantity as a specialized kind of gmeow:Entity, gufo:Object. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Common Companion Terms

gmeow:Entity, gmeow:MeasuredValue, gmeow:ScalarQuantity, gmeow:hasDeterminacy, gmeow:hasGranularity, gmeow:hasReferenceFrame, gmeow:hasUnit, gmeow:assertedAt, gmeow:confidence, gmeow:recordedNoLaterThan

Usage Advice

Use when

• Use as the domain-neutral name for a scalar value bundled with unit/frame, determinacy, and provenance — the same construct as gmeow:ScalarQuantity, preferred when no metrology or observation-result framing is intended.

Avoid when

• Avoid treating it as a distinct class from gmeow:ScalarQuantity / gmeow:MeasuredValue (they are owl:equivalentClass — pick one name per export) and avoid it for currency-framed money (use gmeow:MonetaryAmount).

How to use

• Type the value gmeow:Quantity, set gmeow:quantityValue, name gmeow:hasUnit / gmeow:hasReferenceFrame and gmeow:hasDeterminacy, and carry provenance with gmeow:isResultOf; choose one of the three equivalent names consistently within a projection.

Examples

• ex:distance a gmeow:Quantity; gmeow:quantityValue 12.4; gmeow:hasUnit qudt:M.
