The Open Document Format for Office Applications (also known as OpenDocument or ODF) is an XML-based file format for representing electronic documents such as spreadsheets, charts, presentations and word processing documents.

While the specifications were originally developed by Sun Microsystems, the standard was developed by the OASIS Open Document Format for Office Applications (OpenDocument) TC - OASIS ODF TC,[2] committee of the Organization for the Advancement of Structured Information Standards (OASIS) consortium and based on the XML format originally created and implemented by the office suite (see XML).

In addition to being an OASIS standard, it is published (in one of its version 1.0 manifestations) as an ISO/IEC international standard, ISO/IEC 26300:2006 Open Document Format for Office Applications (OpenDocument) v1.0.[3]


[edit] Specifications

The most common filename extensions used for OpenDocument documents are:[4]

A basic OpenDocument file consists of an XML document that has <document> as its root element. OpenDocument files can also take the format of a ZIP compressed archive containing a number of files and directories; these can contain binary content and benefit from ZIP's lossless compression to reduce file size. OpenDocument benefits from separation of concerns by separating the content, styles, metadata and application settings into four separate XML files.

There is a comprehensive set of sample documents in OpenDocument Format available.[5] The whole test suite is available under the Creative Commons Attribution 2.5 license.

[edit] Standardization

The OpenDocument standard was developed by a Technical Committee (TC) under the 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.[6] 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 December 16, 2002; OASIS approved OpenDocument as an OASIS Standard on May 1, 2005. OASIS submitted the ODF specification to ISO/IEC Joint Technical Committee 1 (JTC1) on November 16, 2005, under Publicly Available Specification (PAS) rules.

After a six-month review period, on May 3, 2006 OpenDocument unanimously passed its six-month DIS ballot in JTC 1 (ISO/IEC JTC1/SC34), with broad participation,[7] after which the OpenDocument specification was "approved for release as an ISO and IEC International Standard" under the name ISO/IEC 26300:2006.[8]

After responding to all written ballot comments, and a 30-day default ballot, the OpenDocument International standard went to publication in ISO, officially published November 30, 2006.

Further standardization work with OpenDocument includes:

[edit] Application support

[edit] Software

The OpenDocument format is used in free software and in proprietary software. This includes office suites (both stand-alone and web-based) and individual applications such as word-processors, spreadsheets, presentation, and data management applications. Prominent office suites supporting OpenDocument fully or partially include:

The OpenDocument Fellowship[24] maintains a list of software and services that support the OpenDocument format. The list also provides information on the status of support for the format.[25]

Various organizations have announced development of conversion software (including plugins and filters) to support OpenDocument on Microsoft's products;[26][27] currently there are nine packages of conversion software.[25] Microsoft has first released support for the OpenDocument Format in Office 2007 SP2.[28] However the implementation faces substantial criticism and the ODF Alliance and others have claimed that the third party plugins provide better support.[29]

Mac OS X 10.5 offers both a new TextEdit version and Quick Look feature supporting the OpenDocument Text format (albeit with some formatting loss).[clarification needed]

[edit] Accessibility

The specification of OpenDocument has undergone an accessibility review, and a few additions were made to version 1.1 of the specification to improve accessibility. Many of the components it is built on, such as Synchronized Multimedia Integration Language and Scalable Vector Graphics, have already gone through the World Wide Web Consortium's Web Accessibility Initiative processes.

[edit] Licensing

[edit] Availability of the standard

Versions of the OpenDocument Format approved by OASIS are available for free download and use.[30]

The ITTF has added ISO/IEC 26300 to its "list of freely available standards"; anyone may download and use this standard free-of-charge under the terms of a click-through license.[31]

[edit] Additional royalty-free licensing on patented software

Key contributor Sun Microsystems made an irrevocable intellectual property covenant, providing all implementers with the guarantee that Sun will not seek to enforce any of its enforceable U.S. or foreign patents against any implementation of the OpenDocument specification in which development Sun participates to the point of incurring an obligation.[32]

A second contributor to ODF development, IBM — which, for instance, has contributed Lotus spreadsheet documentation[33] — 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."[34]

Obligated members of the OASIS ODF TC have agreed to make certain licences available to implementors under the OASIS RF with Limited Terms IPR policy.

[edit] Response

[edit] Support for OpenDocument

Several governments, companies, organizations and software products support the OpenDocument format. For example:

On November 4, 2005, IBM and Sun Microsystems convened the "OpenDocument (ODF) Summit" in Armonk, New York, to discuss how to boost OpenDocument adoption. 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, November 10, 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.[38]

[edit] Criticism

[edit] Worldwide 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. The following is an incomplete list:
