 # MultiDomainInventoryProxy
 Interface towards the MultiDomainInventory
+
+### Location
+The MultiDomainInventoryProxy (MDIP) represents the demarcation towards a higher-layer controller domain.  
+
+### Description
+In principle, the MultiDomainInventoryProxy is a transparent passthrough of requests to existing implementations.  
+
+At its south bound interface, it participates at the OperationKeyManagement that is enforcing the approval regime in the Microwave SDN domain.  
+At its north bound interface, it implements a 1:1 relationship with the ResourceAdapter implementation of the MultiDomainInventory.  
+
+### Relevance
+The MultiDomainInventory is planned to become the major user interface.
