Summary

There are a variety of applications and services which utilize the identification of objects and provide identification services to intended users. However, not all identification applications and services can be considered as those that are tag-based, which incorporate three mandatory functional elements: identifier, identification (ID) tag and ID terminal. Tag-based identification systems and functions are required to be developed to deploy tag-based identification applications and services. Typical tag-based identification systems are ID terminals, identifier resolution systems, object identifier (OID) resolution systems, application-specific OID resolution systems and service brokers. The tag-based identification functions running on the tag-based identification systems incorporate various standards-based implementations that need to be verified for conformity and interoperability. Recommendation Q.3950 identifies target systems and functions that are to be tested and specifies a model network of testing for their conformity and interoperability.
