A schema is a formal specification of the structure, types and constraints that valid data must satisfy within a given system. It defines entities, their attributes, relationships and permissible values, acting as a contract between data producers and consumers. Schemas underpin validation, interoperability and the reliable exchange of structured data across applications.
Overview
- Schema is situated within the Data Model area of the data domain.
- It connects a number of established concepts in the knowledge graph, anchoring edges that previously referenced it without a defining page.
Key aspects

Mechanisms
- Operates through its relationships with Data Model and Data Validation.
- Provides capabilities consumed by dependent and enabled classes listed under Relationships.
Applications
- Supports Data Validation
- Supports Interoperability
