GDS that supports AliasNames, provides AliasNames functionality, but the target Nodes referenced are in other Servers. The AliasNames are aggregated from the Servers that have registered with the GDS that expose the “Alias" capability (for information on capabilities see OPC 10000-12). Additional examples on aggregating AliasNames can be found in the aggregating Server example - A.3. A GDS implementation also requires additional behaviour. This section describes automatic behaviour that is required by all implementations of a GDS that supports AliasNames.

The following sections describe this required behaviour:

The details of the expected behaviour of a GDS that supports AliasNames is described in the following sections.
