4.4.2 Integrated AddressSpace model

AddressSpace is defined in OPC 10000-3 . Servers may subset the AddressSpace into Views to simplify Client access. Subclause 5.3.4.3 describes AddressSpace Views in more detail

5.3.4.3 AddressSpace Views

AddressSpace Views A View is a subset of the AddressSpace . Views are used to restrict the Node s that the Server makes visible to the Client , thus restricting the size ... Client . The default View is the entire AddressSpace . Servers may optionally define other Views . Views hide some of the Node s or References in the AddressSpace . Views are visible

6.6 View Service Set

View Service Set Views are publicly defined, Server -created subsets of the AddressSpace . The entire AddressSpace is the default View , and therefore, the View Services are capable of operating ... AddressSpace . Future versions of this specification may also define Services to create Client defined Views . The View Service Set allows Clients to discover Node s in a View by browsing

5.4 View NodeClass

View . The View Node acts as the root for the Nodes in the View . Views are defined using the View NodeClass , which is specified in Table 10 . All Nodes contained ... ignore View Nodes when exposing the AddressSpace . Simple Clients that do not deal with Views for filtering purposes can, for example, handle a View Node like an Object of type

9.32.3 Views

Views A ModelChangeEvent is always generated in the context of a View, including the default View where the whole AddressSpace is considered. Therefore the only Notifiers which report the ModelChangeEvents ... action generating a ModelChangeEvent may lead to several Events since it may affect different Views . If, for example, a Node was deleted from the AddressSpace , and this Node was also

8.2.3 Views

Views This standard Object is the browse entry point for Views . Only Organizes References are used to relate View Nodes to the " Views " standard Object . All View Nodes ... shall be referenced by this Node , either directly or indirectly. That is, the " Views " Object may reference other Objects using Organizes References. Those Objects may reference additional Views
