part of

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

Universal part-to-whole relation: relates any GMEOW thing to a larger whole it is part of. Transitive and intentionally broad; use specialized subproperties such as gmeow:containedInLocation, gmeow:subOrganizationOf, gmeow:subEventOf, gmeow:partOfThread or module-specific component properties when the kind of parthood matters. No domain/range is asserted so event, location, information-object and endurant parthood all remain possible in OWL 2 DL.

Structure

Property shape: object property

Practical Pattern

Use gmeow:partOf 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.

Usage Advice

Use when

• Use when a generic consumer needs to ask whether one thing is part of a larger whole across domains, or to query the transitive part/whole closure without committing to a specific kind of parthood.

Avoid when

• Avoid when the kind of parthood matters — use a narrower subproperty (gmeow:containedInLocation, gmeow:subOrganizationOf, gmeow:subEventOf, gmeow:partOfThread) — and avoid relying on proper-part, direct-part, or asymmetry semantics, none of which are asserted here.

How to use

• Assert the most specific part/whole subproperty for the domain; generic consumers then read gmeow:partOf by inheritance. Model time-scoped or role-bearing parthood as a relator rather than on this simple transitive spine.

Scope notes

• No cardinality, functionality, asymmetry or irreflexivity is asserted on this transitive property. Proper-part, direct-part and time-scoped mutable parthood must be modelled with narrower simple properties or relators when needed.
