The project was initiated in 2007 as an HP internal REST SDK called Symphony. At the beginning of 2009, HP and IBM joined forces to deliver the Apache Wink project, HP contributed the SDK and IBM contributed a lot of integration tests.
Apache Wink is composed of a Server module and a Client module. The Server module is an implementation of the JAX-RS (JSR-311) specification along with additional features to facilitate the development of RESTful Web services. The Client module is a Java-based framework that provides functionality for communicating with RESTful Web services.
