Celebrating 20 Years of the OASIS Open Document Format (ODF) Standard
A Milestone for Open Document Formats and Digital Sovereignty
Berlin, 1 May 2025 – Today, The Document Foundation joins the open source software and open standards community in celebrating the 20th anniversary of the ratification of the Open Document Format (ODF) as an OASIS standard. Two decades after its approval in 2005, ODF is the only open standard for office documents, promoting digital independence, interoperability and content transparency worldwide.
Originally created as an XML-based format to enable universal access to documents across platforms and software from multiple vendors, ODF has become a technology policy pillar for governments, educational institutions and organisations that choose open, vendor-independent formats to assert their digital sovereignty.
“ODF is much more than a technical specification: it is a symbol of freedom of choice, support for interoperability and protection of users from the commercial strategies of Big Tech,” said Eliane Domingos, Chairwoman of the Document Foundation. “In a world increasingly dominated by proprietary ecosystems, ODF guarantees users complete control over their content, free from restrictions.”
ODF is the native file format of LibreOffice, the most widely used and well-known open source office suite, and is supported by a wide range of other applications. Its relevance – twenty years after its creation – is a testament to the foresight of its creators and the open source community’s commitment to openness and collaboration.
ODF has been adopted as an official standard by ISO (as ISO/IEC 26300) and by many governments on all continents to support digital sovereignty strategies and public procurement policies to ensure persistent and transparent access to content.
To celebrate this milestone, from today The Document Foundation will be publishing a series of presentations and documents on its blog that illustrate the unique features of ODF, tracing its history from the development and standardisation process through the activities of the Technical Committee for the submission of version 1.3 to ISO and the standardisation of version 1.4.
In addition, representatives from the Document Foundation will participate in open source community events to talk about the Open Document Format and highlight its importance to the FOSS ecosystem. The LibreOffice conference will have an entire track dedicated to ODF, coordinated by the OASIS Technical Committee.
