# Core Schema Notation Interoperability Specification
**Documentation Page**: https://sap.github.io/csn-interop-specification/
Core Schema Notation Interoperability (short: CSN Interop) is a powerful and flexible format used to represent the structure and metadata of data and service models in the wider SAP and BTP ecosystem. CSN files are JSON-based and provide a comprehensive way to describe entities, relationships, and other aspects of the model.
