WSDarwin: A web application for the support of REST service evolution

REST has become a very popular architectural style for service-oriented systems, primarily due to its ease of use and flexibility. However, the lightweight nature of its syntax does not necessitate the use of systematic methods and tools. In this work, we argue that such tools can greatly facilitate complex engineering tasks, including service discovery and evolution. We present the WSDarwin set of tools to generate WADL interfaces for REST services, to compare service interfaces to identify differences between versions, and to compare service offerings of different vendors to facilitate service discovery and interoperability.
