Services

Services provide fundamental functionality, without which the application server would fail to function. They correspond to tools in Zope 2's Content Management Framework (CMF), by which some of the semantics were also inspired.

Services do not depend on other components at all. You only interact with other components by passing them as arguments to the constructor or the methods of the service. Any given application should have only a few services that cover the most fundamental functionality. When dealing with locality, services should always delegate requests upward—up to the global version of the service—if a request cannot be answered locally.
