Each asset exposing the hierarchical location as Property has a Property with the BrowseName “HierarchicalLocation” (defined in the Namespace of this specification) and the DataType String or a subtype. The structure of the String (e.g. delimiters for different hierarchies) is not further defined in this specification.
Servers may set the HierarchicalLocation Property to be writable to allow Clients to set the hierarchical location of an asset. Servers may provide the HierarchicalLocation with a Null Value or empty string in case the HierarchicalLocation is unknown to the Server and not set by any Client.
