Hot on the heels of the announcement that OpenDocument 1.0 is now listed as a published standard, ISO/IEC 26300:2006, the final step in the ISO approval process, the Commonwealth of Massachusetts states its acceptance of OpenDocument (ODF).

At the same time, the Commonwealth rejected a pending format, MS Office Open XML (MOOX), being drafted to compete against ODF citing the Commonwealth's requirement that documents remain readable over a longer period of time and stay independent of specific vendors. Another reason is lack of clear commitment to waiving possible patent claims by the owner.
