OpenAPI Overlay Specification helps manage merges and changes in OpenAPI descriptions through prescribed operations.
The UK Open Banking Standards demonstrate how Overlay can be applied to edit API descriptions within an industry framework.
Permitted changes under UK Open Banking Standards include removing API operations, defining recommended values as enumerations, and adding supplementary data.
The Bank of M&D example showcases the use of Overlay to tailor open banking APIs to specific needs, like removing unsupported API operations.
Actions in Overlay, such as updating enum values and adding properties like StructuredDebtorReference, can be applied to enhance API descriptions.
Overlay streamlines the process of editing API descriptions in line with regulations like PSD2 to improve developer experience and compliance.
The ability of Overlay to automate changes based on defined policies enhances the efficiency of managing and updating API descriptions.
Overlay's application extends beyond open banking to other industry standards like healthcare, enabling a systematic approach to API description refinement.
Future enhancements to Overlay could involve automated operations for tasks like removing orphaned objects in API descriptions.
To contribute to shaping the future of Overlay, interested parties can participate in discussions and contribute to the Overlay Specification repository.
