REST (Representational State Transfer) is a software architectural style that was created to guide the design and 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, should behave.

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 ...
The aim of the research of the model as stated by the author was to find out the relationship between the constraints of REST and other forms of web services. [1] It divides the principal parts of RESTful design into three steps: resource identification , HTTP verbs, and hypermedia controls (e.g. hyperlinks). [2]
The Web Application Description Language (WADL) is a machine-readable XML description of HTTP-based web services. [1] WADL models the resources provided by a service and the relationships between them. [1]
There are two previous major description languages: WSDL 2.0 (Web Services Description Language) and WADL (Web Application Description Language). Neither is widely adopted in the industry for describing RESTful APIs, citing poor human readability of both and WADL being actually unable to fully describe a RESTful API.
For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format. 416 Range Not Satisfiable The client has asked for a portion of the file (byte serving), but the server cannot supply that portion. For example, if the client asked for a part of the file that lies beyond the end of the file.
The client can then use SOAP to actually call one of the operations listed in the WSDL file, using for example XML over HTTP. The current version of the specification is 2.0; version 1.1 has not been endorsed by the W3C but version 2.0 is a W3C recommendation. [1] WSDL 1.2 was renamed WSDL 2.0 because of its substantial differences from WSDL 1.1.
