This Recommendation defines an identification scheme for multimedia information access triggered by tag-based identification. This identification scheme is mainly used in the multimedia information system architecture defined in [ITU-T H.621]. It also satisfies the requirements defined in [ITU-T F.771].

This Recommendation does not define encoding rules to store the identifier value into data carriers such as barcode tags and RFID tags. When stored in a data carrier, the OID and identifier value shall be encoded according to the relevant international standards if such standards exist for the type of data carrier.
