| Event date from VitalEvent | date | The date on which the vital event (birth, death, marriage, etc.) occurred. Distinct from the registration date, which is when the event was recorded by a registration authority. |
| Event date estimated from VitalEvent | boolean | Whether the event date is an estimate rather than a known exact date. Common for late-registered births or deaths where the precise date is not documented. |
| Event location from VitalEvent | concept:Location | The specific place where the vital event occurred (for example, the hospital of birth or the place of death). Distinct from the registration location, which is where the event was recorded. |
| Registration date from VitalEvent | date | The date on which the vital event was officially registered with the civil registration authority. May be later than the event date, especially for late registrations. |
| Registration location from VitalEvent | concept:Location | The civil registration office where the vital event was registered. Often a municipal or district-level registry distinct from the place of occurrence. |
| Registration type from VitalEvent | string (crvs/registration-type) | The regime under which the registration was processed: current (within the legal window), late, court-ordered, or reconstruction of a lost record. Affects legal weight and downstream uses. |
| Registrar from VitalEvent | concept:crvs/Person includes Parent | The civil registration officer who recorded the event. In many jurisdictions this is the officer whose signature appears on the acte. |
| Informant from VitalEvent | concept:crvs/Person includes Parent | The person who declares the vital event to the civil registration authority. Typically a parent for births, a relative or medical professional for deaths, or the parties themselves for marriages. |
| Registration status from VitalEvent | string (crvs/registration-status) | The lifecycle state of the registration process for this vital event: whether it is declared, pending validation, registered, rejected, cancelled, or has been corrected or archived. |
| Identifiers from Event | concept:Identifier | Identifiers carried by this entity, such as national ID numbers, program IDs, or identifiers asserted by an identity document. |
| Recognizing parent | concept:crvs/Parent | The parent who is formally recognizing parentage of a child, for example a person acknowledging a child born outside marriage. Captured as a Parent link entity so the parental role-nature and establishment basis are explicit. |
| Child | concept:crvs/Person includes Parent | The child whose birth, adoption, or legitimation is recorded in this event. |
| Mother | concept:crvs/Parent | A convenience reference to the Parent instance whose parental_role is gestational (or, where no gestational parent is recorded, whose certificate_label indicates 'mother'). Retained for compatibility with UN DESA Principles and Recommendations for a Vital Statistics System, Rev 3 (2014), which organizes birth-statistics variables under 'Characteristics of the mother' (Table III.1). Systems that satisfy UN DESA Rev 3 tabulation requirements can derive the 'mother' statistical category by mapping parental_role: gestational to 'mother'. This is a statistical-tabulation helper field, not a modelling assertion that only one parent is a 'mother' or that parenthood is gendered. |
| Birth record reference | concept:crvs/Birth | A reference to the Birth record of the child whose parentage is being recognized, legitimized, or otherwise modified. Links the current event back to the original birth record. |
| Judgment date | date | The date of the court judgment that granted a divorce, annulment, adoption, paternity recognition, or other court-ordered vital event. Distinct from the registration date. |
| Judgment reference | string | The case number or other identifier of the court judgment that ordered this vital event. Enables retrieval of the underlying judicial record. |
| Court | string | The court that issued the judgment for a divorce, annulment, adoption, paternity recognition, or other court-ordered vital event. |
