APIs form the connecting glue between modern applications and are used to connect third-party data services, public/private data sources, and other applications. The Open API Initiative (OAI) came together over two years ago to seek to create, evolve, and promote an open description format for API services that is vendor-neutral, portable, and evolves under shared governance. On August 7, the OAI announced the release of the OpenAPI Spec v3, completing a 7 month community effort. Based upon the open source Swagger project, the world's most popular framework for APIs, the prior version has over 18K daily downloads, over 3k know public GitHub repos, 44 targets in codegen from over 250 contributors. Come join this panel discussion to hear from industry leaders about the origins of the OpenAPI community, and the details of the new OAS v3.0.0 specification release, and the value of open community collaboration related to API development.
