History

Conception

The OpenDocument standard was developed by a Technical Committee (TC) under the Organization for the Advancement of Structured Information Standards (OASIS) industry consortium. The ODF-TC has members from a diverse set of companies and individuals. Active TC members have voting rights. Members associated with Sun and IBM have sometimes had a large voting influence. The standardization process involved the developers of many office suites or related document systems. The first official ODF-TC meeting to discuss the standard was 16 December 2002. OASIS approved OpenDocument as an OASIS standard on 1 May 2005. OASIS submitted the ODF specification to ISO/IEC Joint Technical Committee 1 (JTC 1) on 16 November 2005, under Publicly Available Specification (PAS) rules. ISO/IEC standardization for an open document standard including text, spreadsheet and presentation was proposed for the first time in DKUUG 28 August 2001. 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, after which the OpenDocument specification was "approved for release as an ISO and IEC International Standard" under the name ISO/IEC 26300:2006. After responding to all written ballot comments, and a 30-day default ballot, the OpenDocument

went to publication in ISO, officially published 30 November 2006. In 2006, Garry Edwards, a member of OASIS TC since 2002, along with Sam Hiser and Paul "Marbux" E. Merrell founded the OpenDocument Foundation. The aim of this project was to be open-source representative of the format in OASIS. The immediate aim of this project was to develop software that would convert legacy

documents to ODF. By October 2007 the project was a failure: Conversion of Microsoft Office documents could not be achieved. By this time, The foundation was convinced that ODF was not moving in a direction that they supported. As a result, it announced the decision to abandon its namesake format in favor of

OpenDocument 1.1
'' includes additional features to address accessibility concerns. It was approved as an OASIS Standard on 2007-02-01 following a call for vote issued on 2007-01-16. The public announcement was made on 2007-02-13. This version was not initially submitted to ISO/IEC, because it is considered to be a minor update to ODF 1.0 only, and OASIS were working already on ODF 1.2 at the time ODF 1.1 was approved. However it was later submitted to ISO/IEC and published in March 2012 as "ISO/IEC 26300:2006/Amd 1:2012 – Open Document Format for Office Applications (OpenDocument) v1.1". * '
OpenDocument 1.2
'' includes additional accessibility features, RDF-based metadata, a spreadsheet formula specification based on OpenFormula, support for digital signatures and some features suggested by the public. It consists of three parts: Part 1: OpenDocument Schema, Part 2: Recalculated Formula (OpenFormula) Format and Part 3: Packages. Version 1.2 of the specification was approved as an OASIS Standard on 29 September 2011. It was submitted to the relevant ISO committee under the Publicly Available Specification (PAS) procedure in March 2014. In October 2014, it was unanimously approved as a Draft International Standard. Some comments were raised in the process that needed to be addressed before OpenDocument 1.2 could proceed to become an International Standard. OpenDocument 1.2 was published as ISO/IEC standard on 17 June 2015. * '
OpenDocument 1.3
'' includes additional features for digital signatures, encryption, change-tracking and inter-operability. Version 1.3 of the OpenDocument specification was approved as an OASIS Standard April 2021. The specification was completed as the result of the COSM crowdfunding project seeded by The Document Foundation.

Response

Support for OpenDocument

Several governments, companies, organizations and software products support the OpenDocument format. For example: * The OpenDoc Society runs frequent ODF Plugfests in association with industry groups and Public Sector organisations. The 10th Plugfest was hosted by the UK Government Digital Service in conjunction with industry associations including the OpenForum Europe and OpenUK (formerly Open Source Consortium). ** An output of the 10th Plugfest was an ODF toolkit which includes "Open Document Format principles for Government Technology" that has the purpose of simply explaining the case for ODF directed at the "average civil servant" and includes an extract from the UK Government policy relating to Open Document Format. ** The toolkit also includes a single page graphical image designed to articulate the consequences of not choosing Open Document Format. The illustration has now been translated into more than 10 languages. * Information technology companies like

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. 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." Indeed, adoption by the public sector has risen considerably since the promulgation of the OpenDocument format initiated the 2005/2006 time period. * Different applications using ODF as a standard document format have different methods of providing macro/scripting capabilities. There is no macro language specified in ODF. Users and developers differ on whether inclusion of a standard scripting language would be desirable. * The ODF specification for tracked changes is limited and does not fully specify all cases, resulting in implementation-specific behaviors. In addition, OpenDocument does not support change tracking in elements like tables or

Adoption

One objective of open formats like OpenDocument is to guarantee long-term access to data without legal or technical barriers, and some governments have come to view open formats as a public policy issue. Several governments around the world have introduced policies of partial or complete adoption. What this means varies from case to case; in some cases, it means that the ODF standard has a national standard identifier; in some cases, it means that the ODF standard is permitted to be used where national regulation says that non-proprietary formats must be used, and in still other cases, it means that some government body has actually decided that ODF will be used in some specific context.
