To gain the benefits of Swagger you need to create the YAML documentation this is achieved using a number of new attributes defined on the custom API’s you are creating. With a Swagger-enabled API, you get interactive documentation, client SDK generation and discoverability. With the largest ecosystem of API tooling on the planet, thousands of developers are supporting Swagger in almost every modern programming language and deployment environment making it a great choice to make your REST server easily integrated and used by others. Using a YAML document, you can create Swagger instance of your API. Swagger is a simple yet powerful representation of your RESTful API, and as part of the open tools initiative (joining November 2015) it is backed by members such as Microsoft, Google, PayPal and IBM. This makes it easy to migrate from JSON to YAML if/when the additional features are required. This is also the case in practice every JSON file is also a valid YAML file. YAML can therefore be viewed as a natural superset of JSON, offering improved human readability and a more complete information model. In addition, YAML ventures beyond the lowest common denominator data types, requiring more complex processing when crossing between different programming environments. Thus, YAML allows for extremely readable files, but is more complex to generate and parse. In contrast, YAML’s foremost design goals are human readability and support for serializing arbitrary native data structures. It also uses a lowest common denominator information model, ensuring any JSON data can be easily processed by every modern programming environment. Thus, JSON is trivial to generate and parse, at the cost of reduced human readability.

JSON’s foremost design goal is simplicity and universality. However, JSON and YAML have different priorities. In short, YAML is a human friendly data serialization standard for all programming languages that is a subset of JSON.īoth JSON and YAML aim to be human readable data interchange formats.

YAML: (rhymes with “camel”) YAML Ain’t Markup Language With the release of RAD Studio 10.1 Berlin, it is now possible to do all the above thanks to the new documentation attributes used in EMS packages that create YAML documentation that can be used with Swagger.

To aid adoption of your services you want to create examples for other developers to connect into your server quickly.

You have to keep the documentation updated.So you want to build a new REST server (using Delphi or C++) and want it to become really popular and easily used by other developers.
