The way to migrate IBM Websphere Enterprise Service Bus (WESB) relationship to JBoss Fuse

Issue

We are migrating from IBM Websphere Enterprise Service Bus (WESB) to JBoss Fuse 6.2.1 on EAP 6.4. In WESB, there is a concept called Relationships, where in certain keys and properties can be defined and be retrieved during runtime. It also provides a way to modify the property values/add new properties with out restarting the server or application. Could you please tell us whether there is a similar component in FUSE or EAP? If so, could you please provide us instructions on implementing it.
