Text Quality Rules

A type: text rule is a human-readable expectation written in plain language. It is not executed by datacontract test — it documents an agreement or an expectation that cannot (yet) be automated, so it stays visible in the contract and in generated documentation.

schema:
  - name: orders
    properties:
      - name: order_status
        logicalType: string
        quality:
          - type: text
            description: >
              order_status transitions follow the lifecycle
              placed → shipped → delivered, and never moves backwards.

When to use it

• The expectation is understood and agreed, but you don’t (yet) have a query or metric for it.
• The rule is enforced by an external process and you want to record it in the contract.
• You want to communicate intent to consumers alongside the executable rules.

When you are ready to enforce it automatically, promote it to a SQL or library rule.
