The International Organization for Standardization(ISO) has approved Microsoft’s OOXML as a standard.

ISO/IEC DIS 29500, Information technology – Office Open XML file formats, has received the necessary number of votes for approval as an ISO/IEC International Standard.

Approval required at least 2/3 (i.e. 66.66 %) of the votes cast by national bodies participating in the joint technical committee ISO/IEC JTC 1, Information technology, to be positive; and no more than 1/4 (i.e. 25 %) of the total number of ISO/IEC national body votes cast to be negative. These criteria have now been met with 75 % of the JTC 1 participating member votes cast positive and 14 % of the total of national member body votes cast negative.

Lots of us in India were happy that BIS had decided to vote against OOXML. Short - lived happiness as it turns out.
