vantage

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

The agent or standpoint from which the observation is made — the reified-object-property counterpart of gmeow:accordingTo. Semantically, gmeow:vantage ⊑ gmeow:accordingTo: when an annotated statement is promoted to a reified Observation, its gmeow:accordingTo becomes the gmeow:vantage of the relator. The agent in the vantage role — an observer, a sensor, a perceiver — IS a standpoint (Principle 9): no frame is privileged, and every vantage is a co-equal facet from which the claim is held. Range is gmeow:Entity (encompassing both gmeow:Agent and gmeow:Standpoint) because a vantage may be a bare agent (person, organization, software agent, sensor) or a gmeow:Standpoint individual when the frame needs its own identity. Non-functional: joint observations (a reading co-authored by two agencies) are valid.

Structure

Property shape: object property; gmeow:Observation -> gmeow:Entity

Practical Pattern

Use gmeow:vantage from gmeow:Observation to gmeow:Entity when the relationship itself belongs in the native GMEOW graph.

# Worked example: a measurement is a reified Observation ( P11). A
# gmeow:Measurement records WHAT was observed (gmeow:observedFeature), HOW
# (gmeow:observationMethod), and from WHERE (gmeow:vantage — the sensor). Its
# result is NOT a bare number on the observation: the scalar lives in an
# entity-valued gmeow:ScalarQuantity wrapper that bundles the value with its UNIT
# and uncertainty, so a temperature is never asserted free-floating (P11 — every
# value carries its frame). The unit is aligned to QUDT by reference (P5).

Usage Advice

Use when

• Use to name the agent or standpoint FROM WHICH a reified Observation is held — the relator-edge counterpart of the gmeow:accordingTo annotation, used when an annotated statement is promoted to a first-class Observation and its standpoint needs to be a role player.

Avoid when

• Avoid for the method (gmeow:observationMethod is HOW, vantage is WHO) and for the subject (gmeow:observedFeature); avoid implying the vantage is privileged — every vantage is one co-equal standpoint (Principle 9), so joint and competing vantages coexist.

How to use

• Bind a gmeow:Agent (person, organization, sensor, software agent) or a gmeow:Standpoint individual when the frame needs its own identity; for typed claims assert the bridging subproperty (gmeow:facetVantage, gmeow:usageNamer, gmeow:membershipAuthority) and read gmeow:vantage by inheritance. On the annotation side the same standpoint appears as gmeow:accordingTo.

Scope notes

• gmeow:vantage ⊑ gmeow:accordingTo: the reified relator edge is semantically subsumed by the annotation-property axis. This is NOT asserted as rdfs:subPropertyOf because gmeow:accordingTo is an owl:AnnotationProperty (keeping the OWL 2 DL downcast clean, Principle 3) while vantage is an owl:ObjectProperty. The subsumption is documented here and realised in the projection layer, not axiomatised in the reasoned core.
