         A schema groups model elements and defines a globally unique namespace for it. Typically, elements of the same schema depend on each other and will be used together in a common modeling context.

With regards to OData modeling schemata can be associated with data services, annotation sets or vocabularies. 
Especially vocabularies will be re-used very often. Some vocabularies may always be needed to express very basic modeling aspects, such as service capabilities, unit of measure and currency handling or the like.

Multiple schemata can be stored in files. However, a schema may also be provided by some implementation logic, being distributed like coding, always available consistently and out-of-the-box, independent from any file.

This extension point can be used to register schema provider classes used for OData modeling.
