has participant

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

An agent that took part in an event — the flat 80%-case shortcut. Non-functional. Promote to a gmeow:Participation node when the role, period, confidence, or evidence of the participation must be recorded.

Structure

Property shape: object property; gmeow:Event -> gmeow:Agent

Practical Pattern

Use gmeow:hasParticipant from gmeow:Event to gmeow:Agent when the relationship itself belongs in the native GMEOW graph.

# Worked example: an event on the four orthogonal axes. A wedding has a
# TYPE (eventTypeMarriage), a temporal placement carried in an EXPLICIT frame
# (P11: the instant is meaningless without its TemporalFrame), and a LOCATION —
# three independent axes. The fourth axis is participation: most attendees ride
# the flat gmeow:hasParticipant (the 80% case), but the principals and the
# officiant are promoted to reified gmeow:Participation relators so their ROLES
# are recorded — the reify-on-demand idiom shared with NameUsage.

Usage Advice

Use when

• Use for the 80% case where an event simply has a participant and no role, period, confidence, or evidence needs its own node; period or role on the flat form can ride an RDF-star annotation.

Avoid when

• Avoid it when the role / period / confidence / evidence of the part must be first-class (promote to gmeow:Participation, its reified pair) and when the participant is a non-agent — the flat range is gmeow:Agent, so use a Participation for a document or place.

How to use

• Assert gmeow:hasParticipant per agent for the simple case; promote to a gmeow:Participation (bind via gmeow:participationEvent / gmeow:participationParticipant / gmeow:participationRole) the moment context must be borne — the flat/relator duality recorded by gmeow:pairsWith.

Examples

• ex:wedding gmeow:hasParticipant ex:bride, ex:groom.
