Validation rules

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

  • totalStrataLots should equal the number of StrataLot records for the plan in a complete data set.
  • totalUnitEntitlement should equal the sum of StrataLot.unitEntitlement in a complete data set.

Open questions for legal and industry review

  • Confirm whether additional plan types (for example, mixed building and bare land) need to be represented.
