cloud elements officially joined the open api initiative in november last year to continue the momentum behind organizing the world of apis into easy-to-consume api hubs with standardized, machine-readable documentation .

over the past few months, the members of the oai technical developer community (tdc) have been hard at work to make the next version of the openapi specification a reality: oas 3.0.

open api specification oas 3.0

this week sees the release of the first implementer’s draft of oas v3.0 — officially released as 3.0.0-rc0 — and is a big step forward for the specification.

some of the key changes you’ll see from v2.0 to v3.0 include:

  • the overall structure has been rearranged for easier and extended reusability.
  • json schema support has been extended to include oneof , anyof and not support.
  • the structure of parameters has changed to allow the use of schema in them.
  • support for cookie parameters has been added and dataform parameters have been eliminated.
  • body parameters were extracted to their own entity.
  • support for content type negotiation has been added.
  • a new format to allow static linking between responses and future requests has been added.
  • simplified and enhanced security definitions of apis.
  • a callback mechanism to describe webhooks has been added.

at this point, the specification is feature-complete, and the implementer’s draft is intended to help work through any outstanding issues. we encourage you to get involved by starting to build against oas 3.0 and submit feedback here .
