Validation rules

Cross-field rules beyond what JSON Schema expresses. Documented in the draft; not yet enforced by tooling.

  • endDate must be on or after startDate.
  • partyId must reference a Person when partyType is person, and an Organization otherwise.

Open questions for legal and industry review

  • Ownership is established by the Land Title register. Records in this standard are informational copies, not proof of title.
