International Telecommunication Union

ITUInternational Telecommunication Union´sInternational Telecommunications Union
The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU); it coordinates standards for telecommunications.
Standardization (ITU-T): Standardization was the original purpose of ITU since its inception. Established in 1956 as the International Telephone and Telegraph Consultative Committee or CCITT (from its French name "Comité consultatif international téléphonique et télégraphique"), this sector standardizes global telecommunications (except for radio). In 1993, the CCITT became the ITU-T.

Open Document Architecture

8613-1:1989ODA
One of the most prominent examples of this was the Open Document Architecture project, which began in 1985 when a profusion of software firms around the world were still furiously competing to shape the future of the electronic office, and was completed in 1999 long after Microsoft Office's then-secret binary file formats had become established as the global de facto standard.
The Open Document Architecture (ODA) and interchange format (informally referred to as just ODA) is a free and open international standard document file format maintained by the ITU-T to replace all proprietary document file formats.
