The OData TC has published the OData to OpenAPI Mapping Version 1.0, a recommendation on how to create OpenAPI descriptions for OData services. This project contains two proof-of-concept implementations of that mapping, one using JavaScript, and one using XSLT.

The examples folder contains OpenAPI 3.0.2 descriptions that have been created from the XML $metadata documents of live and example OData services with these proof-of-concept implementations.

The entity-relationship diagrams visualizing the resource models of each service are generated on-the-fly with yUML.
