8.1 Overview

integrate AliasNames into a Global Discovery Server (GDS). AliasNames already define the usage of NodeVersion and ModelChangeEvents to get notification on changes, which is used in this specification as well ... notified if assets have been added or removed, the Client subscribes to the 0: NodeVersion Property or subscribes to ModelChangeEvents . As shown in the example in Figure 2 , the Server
