4.5.3 TagNameplate Interface 
ITagNameplateType includes Properties that are commonly used to describe a TopologyElement from a user point of view.
The TagNameplate Interface is illustrated in Figure 6 and formally defined in Table 19.

AssetId is a user writable alphanumeric character sequence uniquely identifying a component. The ID is provided by the integrator or user of the device. It contains typically an identifier in a branch, use case or user specific naming scheme. This could be for example a reference to an electric scheme.
ComponentName is a user writable name provided by the integrator or user of the component.
Table 20 specifies the mapping of these Properties to the International Registration Data Identifiers (IRDI) defined in ISO/IEC 11179-6. They should be used if a Server wants to expose a dictionary reference as defined in OPC 10001-5.
