sex assigned at birth

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

The sex recorded for a person at birth (a gmeow:SexAssignedAtBirth value) — a RECORDED administrative datum, NOT a self-asserted identity and NOT a gufo IdentityFacet. Deliberately separate from gender identity/expression, which it never implies and is never implied by. Non-functional: a correction and a prior record coexist rather than contradict.

Structure

Property shape: object property; gmeow:Person -> gmeow:SexAssignedAtBirth

Practical Pattern

Use gmeow:sexAssignedAtBirth from gmeow:Person to gmeow:SexAssignedAtBirth when the relationship itself belongs in the native GMEOW graph.

# Worked example: gender as reified, self-asserted, co-equal facets ( P9/P10).
# Each axis is a reified gmeow:IdentityFacet (the NameUsage relator idiom), never a
# flat enum column. Four tenets are visible here:
#   • SELF-ASSERTION is the top authority — a self-asserted facet (selfAsserted
#     true) outranks an external registry record (selfAsserted false), which is
#     SUPPRESSED, never deleted (gmeow:displayable false, P10): kept for provenance,
#     never leaked or displayed.
#   • CO-EQUALITY — gender identity and gender expression are separate facets with
#     no primary/preferred slot; expression is never inferred from identity.
#   • SEX ≠ GENDER — gmeow:sexAssignedAtBirth is a RECORDED administrative datum,
#     not an IdentityFacet, and implies nothing about identity or expression.
#   • OPEN VOCABULARY — values are individuals (gmeow:genderNonBinary, …), never
#     Person subclasses and never a forced enum.

Usage Advice

Use when

• Use to record the administrative sex datum captured at a person's birth, as a value distinct from and never equated with their gender identity or expression.

Avoid when

• Avoid using it as, or inferring it from, gender identity/expression, and avoid it for historical genealogical records (those keep external gedcom:sex); it is a co-equal axis, never a privileged gender selector.

How to use

• Point the person at a gmeow:SexAssignedAtBirth value; leave it non-functional so a correction coexists with a prior record, and add a gmeow:intersexVariation note only where the coarse value is insufficient.

Examples

• ex:lillith gmeow:sexAssignedAtBirth gmeow:saabFemale; gmeow:hasSensitivity gmeow:sensitivitySensitivePersonal.
