An adequate documentation is also key for API maintenance to establish a common understanding of current and future features among all stakeholders. Documenting existing APIs should also be simple and allow inclusion of payload fragments and examples. Considering agile projects and API-first approaches that undergo constant changes, the API itself should preferably adopt automatically.
We thus compare current RESTful modelling specifications to tackle these challenges.
Narrowing down the current specifications on the market based on features, share, surrounding ecosystem and their community only OpenAPI Specification and RAML (RESTful API Modeling Language) remained.
