• The Component registry is a centralised database of registered components and services, which supports multiple management protocols and data models, such as SNMP and TR-069 with TR-181.
• The Component Registrar(CR) in RDK-B Architecture section gives an overview of CCSP Component Registrar, what it contains and illustrates how it is used by other internal components and client applications.
• The “Component Registrar” works like an internal name server.
• Allows other components to register the internal data model objects that they support and the DBuspath used to reach these objects
• Component Registrar provides this information , when other components need to determine what features are available in a particular software build and discover how to access these features
• Through these capabilities, this mechanism provides a flexible way to build a software system that can use any number of software components, allows components to discover what features are available and how to access these features
• Maintains the status and health of all registered components

...

• When a component needs to interact with an object it first asks Component Registrar for a bus address for the object.
• Component Registrar responds with the object address (if the object exists in this software build), hence the object can be accessed.
