Enterprise Services Repository and Registry 
The Enterprise Services Repository (ES Repository) is the central location for defining, accessing, and managing SOA assets (such as Enterprise Services and business objects). It stores the definitions and metadata of Enterprise Services and business processes whilst also providing a central modeling and design environment for creating, aggregating, and using Enterprise Services. The Services Registry supports the publication, classification, and discovery of Enterprise Services.
