The voting has closed on the Open XML ballot, and ISO has issued a press release that explains the outcome:
The five-month ballot process ended on 2 September and was open to the IEC and ISO national member bodies from 104 countries, including 41 that are participating members of the joint ISO/IEC technical committee, JTC 1, Information technology.
Approval requires at least 2/3 (i.e. 66.66 %) of the votes cast by national bodies participating in ISO/IEC JTC 1 to be positive; and no more than 1/4 (i.e. 25 %) of the total number of national body votes cast negative. Neither of these criteria were achieved, with 53 % of votes cast by national bodies participating in ISO/IEC JTC 1 being positive and 26 % of national votes cast being negative.
Comments that accompanied the votes will be discussed at a ballot resolution meeting (BRM) to be organized by the relevant subcommittee of ISO/IEC JTC 1 (SC 34, Document description and processing languages) in February 2008 in Geneva, Switzerland.
The objective of the meeting will be to review and seek consensus on possible modifications to the document in light of the comments received along with the votes. If the proposed modifications are such that national bodies then wish to withdraw their negative votes, and the above acceptance criteria are then met, the standard may proceed to publication.
As Jason Matusow says today, "The next 6 months will be where the rubber really meets the road for the work on Open XML."
