Interaction Diagram: Insert Associations

An IoT Service, the VE & IoT Service Monitoring or even another component in
the system inserts an Association into the Virtual Entity Resolution component.
An association is the relation between a VE-ID and a Service Identifier and is
described by the attribute name and additional information. The call to the
Virtual Entity Resolution component is synchronous and uses the
insertAssociation operation with the Association as parameter. The Virtual
Entity Resolution component inserts the Association into its internal information
base and returns the AssociationID that uniquely identifies the stored
Association. As a result, the updated information required for look-up and
discovery can efficiently be found.
