Web services standards
Web services standards are defined by the World Wide Web and other organizations.
For more information about these standards, refer to the "Web services" section of http://www.w3.org. The Genero Web Services package supports the WSDL 1.1 specification of March 15, 2002 as well as some previous specifications.
Starting with FGLGWS version 3.20, the GWS supports the OpenAPI Specification (OAS), based on the original Swagger 2.0 specification, as the standard for defining and describing RESTful APIs. For more information see the web site at http://www.openapis.org/.
The standards involved in what is commonly called "Web services" include XML, JSON, XML Schema, SOAP, REST, WSDL, and HTTP.
