version member

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

The concrete entity that participates in a version set via this membership — a software release, a book edition, an email variant, a dataset snapshot. Functional per relator: one member per VersionMembership.

Structure

Property shape: object property; gmeow:VersionMembership -> gmeow:Entity; functional Sub-property of: gmeow:observedFeature

Practical Pattern

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

# Worked example: versioning as an authority-scoped claim (Principle 10). A
# gmeow:VersionMembership is a reified Observation: it asserts that an entity
# (gmeow:versionMember) belongs to a gmeow:VersionSet with a gmeow:versionRole
# (canonical / stable / LTS / deprecated / yanked …) and a gmeow:versionScale
# (the size of the change), AS CLAIMED BY an authority (gmeow:membershipAuthority
# / gmeow:vantage). Membership is never overwritten: when a release's role
# changes (stable → deprecated), close the old membership's interval or mint a
# fresh one (P10). Here one release is canonical in the stable channel and, later,
# deprecated — both memberships coexist.

Usage Advice

Use when

Use to name the one concrete version an individual VersionMembership is about — the artifact (release, edition, snapshot) being placed in the lineage.

Avoid when

Avoid pointing it at the lineage concept (that is gmeow:versionSet) and avoid asserting more than one member per relator; it is functional, so a second member collapses the two.

How to use

Set exactly one versionMember on each VersionMembership and pair it with gmeow:versionSet; model a different version of the same lineage as its own membership relator.

ex:m1 gmeow:versionMember ex:gmeow_1_0_1.
