ODF 20th Anniversary Video

On May 1st, 2005, the Open Document Format (ODF) become an OASIS standard. One year after, it became an ISO/IEC standard. After two decades, it is the only true open standard for document formats available on the market, and the only one protecting users from proprietary lock in and ensuring a full control over contents. The presentation provides an overview over ODF features and explains why ODF should be used versus Microsoft OOXML (DOCX, XLSX and PPTX).

Open Document Format (ODF) has been designed as a document standard for the next 20-50 years, to liberate users from the lock-in strategy built into yesterday’s and today’s proprietary formats and foster interoperability. On the contrary, OOXML – approved by ISO/IEC in 2008 in a version never implemented by MS Office – has been designed as a document pseudo-standard format to propagate yesterday’s document issues and lock-in strategy for the next 20-50 years, to the detriment of users and interoperability.

The philosophy behind the ODF standard document format was to design a mechanism in a vendor neutral manner from the ground up, using existing standards wherever possible. Although this means that software vendors had to tweak their individual packages more than if they continued down their original routes, the benefits for interoperability were important enough to justify this objective. The OOXML pseudo-standard document format was designed by Microsoft for Microsoft products, and to interoperate with the Microsoft environment. Little thought appears to have been exercised for interoperability with non-Microsoft environments, or compliance with established vendor-neutral standards.

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.

Germany committing to ODF and open document standards

Digital sovereignty is of vital importance for data freedom. If governments and organisations use proprietary or pseudo-standard formats, they limit the tools that citizens can use to access data.

So we’re happy to see that the IT Planning Council in Germany is committing to move to the Open Document Format – a fully standardised format (and the default used in LibreOffice). The German IT Planning Council is a 17-member committee consisting of representatives of Germany’s federal government and the state governments. They say:

Open formats and open interfaces are an important building block for the necessary transformation process of public administration in Germany on the path to greater digital sovereignty and innovation.

The IT Planning Council is committed to ensuring that open formats such as the Open Document Format (ODF) are increasingly used in public administration and become the standard for document exchange by 2027. It is commissioning the Standardization Board to implement this.

Celebrating Document Freedom Day

Why Document Freedom Day Matters More Than Ever

Every year, Document Freedom Day reminds us of a simple but powerful idea: we should have control over our own data. Not just where we store it, but how we access it, share it, and keep it usable for years to come. At the heart of that is the concept of open standards, file formats that anyone can read, use, and build on without restrictions.

What’s Document Freedom, Anyway?

Document freedom means being able to create and access digital documents without being locked into a specific company’s software. When you save a file – whether it’s a spreadsheet, a report, or a photo album – you should be able to open it on any system, now or in the future. That’s only possible with open standards like ODF (Open Document Format) or PDF/A.

Proprietary formats can trap your content. Ever tried opening an old project and found that the software doesn’t exist anymore or now requires a subscription? That’s the problem. Your data shouldn’t expire just because a company changed its business model.

Why It Matters

For individuals, it’s about ownership. You shouldn’t lose access to your writing, photos, or work just because you switch devices or software.
For organizations, it’s about long-term access and avoiding vendor lock-in.
For governments, it’s about transparency and accountability. Public records must remain readable and accessible over time.

How You Can Support Document Freedom

– Use software that supports open formats (like LibreOffice or LibreOffice Technology based software).
– Save and share files in open formats like .odt, .ods, or .pdf (not .docx, .xlsx, etc.).
– Push for open standards in your workplace or community projects.
– Spread the word: most people don’t even realize file formats can trap them.

The Bigger Picture

Document freedom is part of a broader movement for digital rights. It’s about giving people real choices and protecting their autonomy in the digital world. As AI, cloud services, and proprietary platforms grow more complex, the risks of losing control over our content also grow. Open standards are a small but essential line of defence.

So today, take a minute to think about the files you create. Are they truly yours to keep?

Happy Document Freedom Day

REMINDER: Document Freedom Day @ LibreOffice

Next Wednesday, on March 26, we will celebrate Document Freedom Day 2025. During the day, we will mainly talk about the ISO Open Document Format, which was approved in 2005 by OASIS and in 2006 by ISO. Due to the global scale of the LibreOffice project, our events will be online.

There will be three webinars at 10:30 CET, 15:30 CET and 20:30 CET, with a presentation on the history of ODF and the great importance of the standard document format for digital sovereignty. To listen to the webinars, you can connect to https://jitsi.documentfoundation.org/dfd2025.

We will also be connected for question and answer sessions at 1 p.m. CET and 6 p.m. CET, to delve deeper into the topics of the webinar and to satisfy the curiosity of users, most of whom use a proprietary format without being aware of it, and are therefore victims of Microsoft’s lock-in strategies. These sessions will be in the same video room as the webinars: https://jitsi.documentfoundation.org/dfd2025.

Document Freedom Day: Empowering the Digital World with Open Standards

Every year, on the last Wednesday of March, advocates of free and open technologies come together to celebrate Document Freedom Day (DFD). In 2025, the Document Freedom Day will happen on March 26, and will be driven by the LibreOffice community.

Today, Document Freedom Day – together with Software Freedom Day (SFD, celebrated in September) and Hardware Freedom Day (HFD, celebrated in April) – is coordinated by the Digital Freedom Foundation (DFF). This global event raises awareness about the importance of open standards and accessible formats in the digital age, empowering individuals, organizations, and governments to embrace freedom in how they create, share, and preserve information.

But what exactly is Document Freedom Day, and why is it so crucial in today’s world? Let’s explore its significance, the challenges posed by proprietary formats, and how embracing open standards can create a more inclusive, transparent, and resilient digital future.

What is Document Freedom Day?

Document Freedom Day was established by the Free Software Foundation Europe (FSFE) to promote the use of open standards for documents, and transferred to the Digital Freedom Foundation in 2016. It is a day dedicated to advocating for formats and tools that ensure documents can be accessed, edited, and shared by anyone, without restrictions or reliance on specific software or vendors.

At its core, Document Freedom Day celebrates the idea that information should be accessible to all. It highlights the need for transparency and interoperability in digital documents, ensuring that no one is excluded or locked into using a particular platform due to proprietary constraints.

The Problem with Proprietary Formats

Proprietary formats come with significant drawbacks. They are typically controlled by a single company or entity, meaning that access to these formats can be restricted or even revoked at any time. This lack of control over how information is stored and accessed poses numerous challenges:

  1. Vendor Lock-In: Proprietary formats often force users to rely on specific software, limiting their choices and tying them to a single vendor. This can lead to long-term costs, as organizations may have to pay for updates, licensing fees, or migration to alternative platforms.
  2. Inaccessibility: Over time, older proprietary formats may become obsolete, making it difficult or impossible to access historical data. This is especially problematic for governments, libraries, and archives that need to preserve information for future generations.
  3. Lack of Transparency: Proprietary formats often hide how data is stored, making it harder to verify, analyze, or integrate with other systems. This lack of transparency can lead to inefficiencies and mistrust.
  4. Exclusion: Individuals who cannot afford expensive software or who use alternative platforms may find themselves excluded from accessing or sharing documents.

The Power of Open Standards

Open standards offer a solution to these challenges by providing formats that are publicly available and free from restrictive licensing. They are designed to be:

  • Interoperable: Open standards enable seamless communication between different software and systems, allowing users to share and access information across platforms.
  • Accessible: They ensure that anyone, regardless of their tools or financial resources, can access and use the information.
  • Future-Proof: Open standards are often maintained by global communities or non-profit organizations, ensuring their longevity and adaptability.
  • Transparent: By making the technical details publicly available, open standards allow developers to innovate and improve upon existing formats.

Prominent examples of open standards include the Open Document Format (ODF) for text documents, the Portable Document Format (PDF/A) for archiving, and Web standards like HTML and CSS. These formats demonstrate how openness can foster innovation and inclusivity.

One notable milestone in the history of open standards is the adoption of the Open Document Format (ODF) as an official OASIS standard in 2005. ODF was designed to provide a universal, vendor-neutral format for office documents, ensuring that users could create, edit, and share files without being tied to proprietary software. Its standardization marked a significant step forward in the global movement toward greater document freedom.

Why Document Freedom Matters

Document freedom is not just a technical issue; it is a matter of rights, equity, and sustainability. Here are a few reasons why it matters:

  1. Empowering Individuals. When people have control over their documents, they gain the freedom to choose the tools that work best for them. Open standards ensure that individuals can access and share information without being constrained by expensive or restrictive software.
  2. Promoting Innovation. By removing barriers created by proprietary formats, open standards encourage competition and creativity. Developers can build new tools and applications that work with existing formats, driving technological progress.
  3. Ensuring Long-Term Preservation. For governments, libraries, and cultural institutions, preserving historical records is a critical responsibility. Open standards ensure that documents remain accessible over time, regardless of changes in technology or vendor policies.
  4. Fostering Inclusivity. Open standards create a level playing field, enabling people from diverse economic and technological backgrounds to participate in the digital world. This inclusivity is essential for bridging the digital divide.

How to Get Involved in Document Freedom Day

A Vision for the Future

Document Freedom Day is more than just a celebration; it is a call to action. It reminds us of the importance of building a digital world where everyone can participate, innovate, and thrive without unnecessary barriers. On March 26, the LibreOffice community will organize a virtual event with a presentation about the importance of open document standards for digital sovereignty (technological independence from US companies), followed by an open discussion. We will provide details about this virtual event, which will be repeated during the day to allow people from all time zones to participate, around mid-March.

As we face challenges like rapid technological change, increasing reliance on digital communication, and the need for greater inclusivity, the principles of openness and freedom become ever more critical. By embracing open standards, we can create a future where information is a shared resource, accessible to all and preserved for generations to come.

So, this Document Freedom Day, take a moment to reflect on how you interact with digital information. Advocate for openness, educate others, and join the global community working to make document freedom a reality. Together, we can ensure that the digital world remains a space of opportunity and equality for everyone.
