The OpenAPI Initiative (OAI) was created by a consortium of forward-looking industry experts who recognize the immense value of standardizing on how APIs are described. As an open governance structure under the Linux Foundation, the OAI is focused on creating, evolving and promoting a vendor neutral description format. The OpenAPI Specification was originally based on the Swagger Specification, donated by SmartBear Software.

Several key members of the OpenAPI Initiative project presenting at the API Specifications Conference 2019.
We are going virtual, making it even easier to participate! Hold the date for the API Specifications Conference (ASC) 2020 online conference in the 2nd week in September. Details coming soon.
