A new ITU-T standard unifies identification schemes used for example in multimedia mobile applications. Currently no uniform way exists to reconcile the many different ID schemes in place now, or to be defined.

The standard - Rec. ITU-T X.668 - concentrates on what it calls tag-based applications and services. This description includes RFID and bar code 'tags'. The standard allows the referencing of schemes using the object identifier (OID) system which ITU-T and ISO/IEC developed in the 1980s and widely deployed, for example, in e-commerce applications.

The introduction of this standard will not cause existing tags to become obsolete. Given deployment of the standard, a tag placed on a billboard poster can be read with a mobile phone and make it easy for the user to get additional multimedia (text, graphics, even voice or video) information about the content of the poster.

ITU-T X.668 is the first and key stage in the standardization process with the next work focussing on specifications of the system and protocol that will associate the multimedia information to an ID (a.k.a. ID resolving).

Technically, this Recommendation (also published as an equivalent ISO/IEC International Standard) specifies the information and justification to be provided when requesting an OID for identification schemes for tag-based applications and services, and the procedures for the operation of the Registration Authority (see here). It was jointly authored by experts from ITU-T Study Groups 17 (with input from SG 13 and SG 16) and ISO/IEC. The original drive for the work came from Korea's Electronics and Telecommunication Research Institute (ETRI).
