has part

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

Universal whole-to-part inverse of gmeow:partOf. Transitive and intentionally broad; specialized component and containment properties remain the authoritative source for domain-specific meaning.

Structure

Property shape: object property

Practical Pattern

Use gmeow:hasPart when the definition matches the source fact. Prefer a narrower GMEOW term when one exists, and keep projection concerns in the mapping layer.

# Worked example: the kernel disclosure machinery (Principles 10 and 12). Any entity can
# declare HOW SENSITIVE it is (gmeow:hasSensitivity), the POLICY governing its
# release (gmeow:hasDisclosurePolicy), and WHICH CONSUMERS are eligible to receive
# it (gmeow:eligibleForConsumer → a ProjectionContext). This is the projection/
# disclosure boundary: a confidential record is never deleted, only withheld from
# the wrong consumer (P10 suppression, P12 solver/presentation split). Part-whole
# mereology (gmeow:partOf / gmeow:hasPart) and gmeow:hasDeterminacy (how crisp the
# value is) are the other kernel primitives every slice reuses.

# Worked example: an agreement as a relator. A gmeow:Agreement (here a
# gmeow:Contract, the legally-enforceable specialization) is a gufo:Relator that
# binds its parties via gmeow:hasParty — the agreement IS the relationship, not a
# property of either party. It bears a structured gmeow:AgreementName (an
# Appellation, so multilingual co-equal titles are first-class). Other relators
# can be gmeow:foundedOn it: the employment Membership below exists BECAUSE of the
# contract, so its grounding is recorded rather than assumed.

# --- The contract: a relator binding the two parties, bearing a formal name.
#     (Validity bounds — gmeow:validFrom/validUntil — are statement-level RDF-1.2
#     annotations, carried in the statement layer rather than as A-box triples.)

Usage Advice

Use when

• Use when traversing or projecting from whole to part across domains, or when a renderer needs a generic decomposition without committing to one privileged part model.

Avoid when

• Avoid asserting gmeow:hasPart directly when a domain subproperty exists; assert the specialized part relation (or its inverse) and let gmeow:hasPart follow by inheritance and inversion.

How to use

• Prefer asserting gmeow:partOf (or a domain subproperty) and read gmeow:hasPart as its inverse; reach for it explicitly only in whole-rooted projections where the inverse direction is the natural one to state.

Scope notes

• Generic has-part is a query/projection convenience, not a single privileged decomposition model. Consumers that need spatial, organizational, event or information-object semantics should use the corresponding specialized subproperty.
