The ITopologyWorkspace interface provides access to the OpenTopology method that allows you open a topology within a workspace given only the topology�s name. Use this interface to open a topology when you only have a reference to a workspace object. For ArcSDE Geodatabases, the fully qualified name can be used to return topologies owned by specific users. If multiple topologies with the same name are owned by different users, OpenTopology will return the topology owned by the current user if an unqualified name is supplied.
