The RESTful Service Description Language (RSDL) is a machine- and human-readable XML description of HTTP-based web applications (typically REST web services). [1]The language (defined by Michael Pasternak during his work on oVirt RESTful API) allows documenting the model of the resource(s) provided by a service, the relationships between them, and operations and the parameters that must be ...
REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web
Introduces resources and allows requests for individual URIs (still all typically POST) for separate actions instead of exposing one universal endpoint (API). The API resources are still generalized but it is possible to identify the scope of each one. Level One design is not RESTful, yet it is organizing the API in the direction of becoming one.
Instead, the client is given a set of entry points and the API is discovered dynamically through interaction with these endpoints. HATEOAS was introduced in Roy Fielding's doctoral thesis Architectural Styles and the Design of Network-based Software Architectures. HATEOAS is one of the key elements distinguishing REST from RPC mechanisms. [3]
The HTTP/1.0 specification [49] defined the GET, HEAD, and POST methods as well as listing the PUT, DELETE, LINK and UNLINK methods under additional methods. However, the HTTP/1.1 specification [50] formally defined and added five new methods: PUT, DELETE, CONNECT, OPTIONS, and TRACE. Any client can use any method and the server can be ...
Jakarta RESTful Web Services, (JAX-RS; formerly Java API for RESTful Web Services) is a Jakarta EE API specification that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern. [1]
Together, the endpoint and the query string form a URL that determines how the API will respond. This URL is also known as a query or an API call. In the below example, two parameters are transmitted (or passed) to the API via the query string. The first is the required API key and the second is an optional parameter — the date of the ...
Starting with HTML 4.0, forms can also submit data in multipart/form-data as defined in RFC 2388 (See also RFC 1867 for an earlier experimental version defined as an extension to HTML 2.0 and mentioned in HTML 3.2). The special case of a POST to the same page that the form belongs to is known as a postback.
