Ensemble ReST is a software system that eases the development, deployment, and maintenance of server-side application programs to perform functions that would otherwise be performed by client software. Ensemble ReST takes advantage of the proven disciplines of ReST (Representational State Transfer — a style of software architecture for such distributed hypermedia systems as the World Wide Web) and OSGi (formerly, Open Services Gateway Initiative — an industry standard for software for connecting such devices as home appliances and security systems to the Internet). ReST leverages the standardized HTTP protocol to enable developers to offer services to a diverse variety of clients: from shell scripts to sophisticated Java application suites.
