Yesterday ISO, the International Standards Organization, finally made the OpenDocument Format (ODF) specification into a real ISO standard by pushing the specification into stage 60/60. This means that every government on earth could -- and indeed should -- specify ODF as the preferred format for storing office files. For more details, see ISO's webpage.
After this specification is approved as the real ISO standard, i hope that Indonesian government also start consider this standard as the national standard just like what happened in Malaysia, Massachusetts, and several countries around the world who has started to adopt ODF as the national format. By using this standard format, it will be guaranteed that the file can be accessed by any ODF-compliant application, including OpenOffice.org, KOffice, Abiword, and also commercial application, including Microsoft Office and StarOffice.
