What problem does it solve?

It prevents downstream failures by turning “just a schema” into an explicit, testable Data Contract that covers meaning, grain, freshness, quality, access, lineage, and change/deprecation behavior.

Core Features & Use Cases

  • Data Contract Specification: Define producer/consumer/owner expectations and a contract scope for sources, Silver, Gold, serving outputs, and downstream systems.
  • Consumer-risk-based contract levels: Use contract levels (None/Minimal/Standard/Full/External-Regulated) to match governance strictness to dependency risk.
  • Validation-ready obligations: Produce contract content that Phase 13+ can later transform into checks, gates, and operational controls (without implementing code here).

Quick Start

Use des-data-contracts to create _des-output/planning-artifacts/12-data-contract-specification.md for Gold and serving outputs that consumers will rely on.
