Standardization of Office Open XML

The Office Open XML file formats were standardised between December 2006 and November 2008, first by the Ecma International consortium (where they became ECMA-376), and subsequently, after a contentious standardization process, by the ISO/IEC's Joint Technical Committee 1 (where they became ISO/IEC 29500:2008).
