Hasura's Data Delivery Network (DDN) implements a Universal Data Access Layer (UDAL) through a supergraph architecture, serving as both orchestrator and guardian in decentralized data environments to validate data contracts and relationships, orchestrate operations while enforcing security policies, provide abstraction from underlying technical implementations, identify semantic ambiguity and imprecision in the data model, but lacking a temporal database that tracks how metadata evolves. Tracking metadata evolution is crucial for understanding changes in the rules and shapes of data, enabling robust governance and intelligence through insights into usage patterns, quality impact analysis, cross-domain intelligence, and predictive analysis. Temporal tracking simplifies governance by letting users compare states between any points, track policy lifecycles, understand contexts behind changes, and provide auditors with comprehensive historical evidence, invaluable for governance teams enforcing standards. Implementing temporal tracking doesn't require specialized databases, using a straightforward pattern that works with existing databases, and Hasura has open sourced the Temporal Data Catalog Connector on GitHub to facilitate implementation details and code.
