The proposal is from http://wiki.apache.org/incubator/WinkProposal
Apache Wink is a project that enables and simplifies development of REST style HTTP based services. The project includes both server and client side components that can be used independently of each other. The server side is a stand-alone component that integrates easily with many existing application servers. The client side API enables the user to develop applications that interact with server resources in a RESTful manner. The goal is to provide component technology for both RESTful services and clients that can be used in a number of contexts. These contexts could range from a full Java EE runtime environment (Geronimo) to a J2SE environment with a simple HTTP listener service.
The server component of Apache Wink will implement a TCK compliant version of the JAX-RS standard defined by JSR 311 ( https://jsr311.dev.java.net/). The client side component provides a rich API for quickly developing applications that access and update server resources using JAX-RS requests. The API can accommodate data returned in several popular formats including JSON, XML, ATOM, HTML and CSV. Plans for future extensions are currently being discussed, but include a focus on ease of use through service discovery and quality of service configuration (security, caching).
