[17] After a six-month review period, on 3 May 2006, OpenDocument unanimously passed its six-month DIS (Draft International Standard) ballot in JTC 1 (ISO/IEC JTC 1/SC 34), with broad participation,[18] after which the OpenDocument specification was "approved for release as an ISO and IEC International Standard" under the name ISO/IEC 26300:2006.

In 2006,[20] Garry Edwards, a member of OASIS TC since 2002,[21] along with Sam Hiser, and Paul "Marbux" E. Merrell[22] founded the OpenDocument Foundation.

Prominent text editors, word processors and office suites supporting OpenDocument fully or partially include: Various organizations have announced development of conversion software (including plugins and filters) to support OpenDocument on Microsoft's products.

[54] However, the implementation faced substantial criticism and the ODF Alliance and others claimed that the third party plugins provided better support.

[55] Microsoft Office 2010 can open and save OpenDocument Format documents natively, although not all features are supported.

[57] Starting with Mac OS X 10.5, the TextEdit application and Quick Look preview feature support the OpenDocument Text format.

[61] A second contributor to ODF development, IBM – which, for instance, has contributed Lotus spreadsheet documentation[62] – has made their patent rights available through their Interoperability Specifications Pledge in which "IBM irrevocably covenants to you that it will not assert any Necessary Claims against you for your making, using, importing, selling, or offering for sale Covered Implementations.

The ODF Summit brought together representatives from several industry groups and technology companies, including Oracle, Google, Adobe, Novell, Red Hat, Computer Associates, Corel, Nokia, Intel, and Linux e-mail company Scalix (LaMonica, 10 November 2005).

The providers committed resources to technically improve OpenDocument through existing standards bodies and to promote its usage in the marketplace, possibly through a stand-alone foundation.

[72] Scholars have suggested that the "OpenDocument standard is the wedge that can hold open the door for competition, particularly with regard to the specific concerns of the public sector.

"[73] Indeed, adoption by the public sector has risen considerably since the promulgation of the OpenDocument format initiated the 2005/2006 time period.
