Interface Summary

Interface	Description
AbstractCFMetaDataFactory.Parser	Internal parser interface.
AbstractCFMetaDataFactory.Serializer	Internal serializer interface.
MetaDataContext	Allows us to access configuration through metadata in a generic way.
MetaDataDefaults	Populates new metadata with default values.
MetaDataFactory	The MetaDataRepository uses implementations of this interface to load and store metadata.
