How CAS Stores a Data Object Application Server Client CAS API Object ID Client presents data to API to be archived 1 Unique Content Address is calculated 2 Object is sent to CAS via CAS API over IP 3 CAS authenticates the Content Address and stores the object 4 Acknowledgement returned to application 5 Object-ID is retained and stored for future use 6

How CAS Retrieves a Data Object Application Server Client CAS Object is needed by an application 1 CAS authenticates the request and delivers the object 4 Application finds Content Address of object to be retrieved 2 Retrieval request is sent to the CAS via CAS API over IP 3 API Object ID
