Overview

A CompositeService is a service that consists of a number of services working together to provide a single service. For example a web forum service might consist of a MySQL service, for persistant storage, and a Ruby HTTP service that serves HTML sites and queries the storage. In the CompositeService you may choose to only expose the HTTP service, making it only possible to query the MySQL database through the Ruby application, which might be considered proper encapsulation.

Relations between services are described by the links attribute. A link is characterized by a producer and a consumer, the consumer will connect to the producers provided service.
