This standard Object Node is the browse entry point for ObjectType Nodes that represent Interfaces. Figure 8 illustrates the structure beneath this Node showing some of the standard ObjectTypes defined in clause 6. Only Organizes References are used to relate Objects and Interfaces to the “InterfaceTypes” standard Object. The “InterfaceTypes” Object shall not reference any other NodeClasses.

Figure 8 – InterfaceTypes Organization

The intention of the “InterfaceTypes” Object is that all Interfaces of the Server are either directly or indirectly accessible browsing HierarchicalReferences starting from this Node. However, this is not required and Servers might not provide some of their Interfaces because they may be well-known in the industry.

The “InterfaceTypes” Object is formally defined in Table 105.
