This service represents the Repository Data Dictionary. The dictionary
provides access to content meta-data such as Type and Aspect descriptions. Content metadata
is organized into models where each model is given a qualified name. This means that it is
safe to develop independent models and bring them together into the same Repository without
name clashes (as long their namespace is different).
