The philosophy behind ODF: openness, freedom and control

File formats are not usually the subject of philosophical debate because most users just want to open, save and share documents without any problems. However, the Open Document Format (ODF) is based on concepts that are much more important to users than might initially seem the case. ODF is not just a technical standard, but also a statement of openness, user freedom, and control over digital information.

Understanding this philosophy helps to explain why ODF exists, why it is still important, and why it is often cited as a reference in conversations about digital rights and long-term access.
In short, ODF is an open standard for office documents such as text files, spreadsheets and presentations, and it is the native format of LibreOffice. Unlike Microsoft Office and Microsoft 365 files, which use a proprietary format developed in secret in Redmond and controlled by Microsoft, ODF is developed and maintained through a completely transparent process.

This may seem like a technical detail, but it is an important fact that determines everything else.

Openness: no one owns your documents

The principle behind ODF is openness. The complete specifications are available to the public, and anyone can read, implement or create software based on them without asking for permission or paying licence fees.

This has concrete consequences:

  • Developers can create compatible software without facing legal barriers.
  • Organisations can adopt ODF without being tied to a single supplier.

Users can manage their own documents without having to use a specific company’s tools.

Openness is not idealism for its own sake, but rather it means transparency and durability. When a format is open, knowledge of how it works does not disappear if a company changes direction, raises prices, or stops producing software.

Documents created today should still be readable decades from now. ODF was designed with this long-term perspective in mind.

Freedom: choice without penalties

In the context of ODF, freedom is primarily about choice.

With proprietary formats, even a simple software update can lead to hidden costs because files may not open correctly, formatting may not work and some features may disappear. Over time, this can discourage users from abandoning software, even if better or cheaper options exist.

ODF counteracts this dynamic.

Since multiple applications support the same format, users can choose the tools that best suit their needs. For example, you can write a document in one programme, edit it in another, and store it in a standard, open format, safe in the knowledge that it will be compatible.

This is particularly important for public institutions, schools and governments. When documents need to be accessible to all, tying them to a single vendor’s software creates an unnecessary barrier that goes against the democratic principle of equality. ODF supports the idea that public information should be readable using freely available tools.

In this context, freedom does not imply hostility towards commercial strategies, but rather respect for every user’s right not to be discriminated against because of file format.

Control puts power in the hands of the user

Control is the most overlooked part of the ODF philosophy.

When you save a document in a proprietary format, you often have to rely on undocumented behaviour, hidden features, or licence terms that have simply been imposed without negotiation. The supplier decides how the format changes and which features remain accessible to which users.

ODF reverses this relationship.

In fact, a standard format that is openly governed cannot be changed unilaterally by a single organisation. All decisions are discussed, documented and agreed upon through a public, transparent process. This guarantees that users and organisations will not be affected by a company’s strategies or held hostage by changes to their data.

Control also manifests itself in smaller, everyday ways. For example:

  • ODF files can be inspected: they are actually ZIP archives containing XML text that can be read by anyone, even those unfamiliar with the technology.
  • Documents can be automated, validated or processed using open tools.
  • You can migrate archives without having to reverse engineer a closed format.

This type of control is essential for legal documents, scientific data, historical archives and any other data that must remain intact and accessible over time.

Is ODF still important today?

In the era of cloud-based editors and collaborative platforms, it is reasonable to ask whether ODF is still relevant.

The answer is yes, perhaps more than ever.

Moving an increasing number of documents online takes control away from users because the files reside on servers that they do not manage and are in formats that they neither understand nor control. They are also governed by licence terms that users almost always sign without reading and which can change at any time.

ODF also sets a benchmark when the cloud is used for storage because an open, standard format guarantees the integrity and accessibility of data, regardless of users’ level of expertise. Thus, ODF protects users from their own unawareness of the format issue.

ODF also acts as a silent check on market power, reminding the software ecosystem that users must be able to switch applications without losing access to their content, which must remain their property and under their complete control.

The ODF philosophy is practical, not abstract, and translates into tangible results: reduced barriers, longer-lasting documents and greater choice.

Users do not need to become experts in standards or understand the specifics of the files to take advantage of this. ODF guarantees them permanent ownership of their work and the ability to manage it at any time with the software they prefer. This frees them from any constraints imposed by a supplier or tool that they have not chosen freely.

In this sense, ODF is not just a format, but also a reminder that digital files should serve the people who create them — not the other way around.

State of the Project – Calendar Year 2025

Starting in January 2026, at the beginning of each quarter, i.e. in January, April, July and October, I will publish a slide deck with updated statistics on the LibreOffice project.

Unless there are specific requirements, the statistics will refer to the last 12 calendar months. Therefore, the January statistics will refer to the 2025 calendar year, while the next ones will refer to the period from April 2025 to March 2026, and so on.

All published information is available online for further processing. Links to data sources are on the penultimate slide, with some notes on data processing.

If you have any questions or suggestions, please write to me: my email address is on the last slide.

Why open standards are extremely beneficial to end users

Whenever I talk to other technology users — including CTOs, CSOs and ICT managers, who in theory should have a certain level of expertise — I realise that most of them never consider standards when using applications, devices or websites.

Users just want everything to work, but they don’t realise the fundamental role that standards, especially open standards, play in making this happen. Open standards actually offer users a significant advantage over the proprietary solutions they use every day.

An open standard is a publicly available set of rules that govern how technology works. Anyone can use, develop or improve them. Examples include HTML for websites, USB for devices and PDF for documents. (And of course, the Open Document Format – ODF – as used by LibreOffice.) These are not owned by any company, and therefore benefit end users.

That’s why they’re important to you.

1. You are not tied in

Open standards reduce vendor lock-in. This means that users are not forced to use a single product or ecosystem from a single company to have control over their data and tools.

For example, documents saved in an open format can be managed with multiple applications. If you change your device or software, your files will still work. You can choose the best solution for you, rather than being forced to use what the supplier provides.

It’s easy to take this freedom for granted until it’s gone. Just ask the Windows 10 users who had to abandon working software and PCs due to Microsoft’s business strategies.

2. Better compatibility between devices and applications

Open standards enable different products to work together more seamlessly. For example, your phone can connect to any laptop, your browser can open any website and your headphones can connect to any device. None of this is accidental. It is the result of open, shared standards.

For end users, this means fewer headaches and less time spent troubleshooting or wondering why something ‘should work’ but doesn’t.

3. More competition and better products

When standards are open, more companies can use them. This increases competition.

Competition leads to better prices, more advanced features, and much faster growth. Instead of handcuffing users with proprietary formats, companies must earn their trust.

As users, you benefit from greater choice and improved quality throughout the entire value chain.

4. Longer data life

Proprietary formats can disappear. Companies may change direction, discontinue products or go out of business. Ask the Windows 10 users mentioned earlier for more information.

Open standards tend to last much longer because they are not tied to the business strategies of a single company. Even after decades, data stored in an open format remains accessible, convertible and preservable.

This is important if users want their photos, documents or work to survive for longer than the lifespan of a single product.

5. Better accessibility

Open standards are often designed with accessibility in mind or to facilitate the proper functioning of accessibility tools.

Screen readers, alternative input devices and assistive software all rely on consistent, documented rules. When standards are open, developers and accessibility experts can test, improve and adapt them.

The result is technology that works better for more users.

6. Greater transparency and trust

With open standards, the rules are visible. Anyone can examine, test and report on them.

This transparency helps to identify security issues earlier and reduces the risk of behaviour that only benefits one supplier going unnoticed. While open does not automatically mean secure, it does mean fewer black boxes.

Over time, this increases users’ trust in the technology.

7. A healthier technology ecosystem

Open standards encourage collaboration and combat fragmentation between products because developers can focus on improvements rather than reinventing the basics or figuring out how to work around closed systems.

A healthier ecosystem means faster innovation and fewer dead ends for users. Things evolve, but they don’t break all the time or at the whim of vendors who rely on planned obsolescence.

Summary

In short, open standards are not flashy and are rarely directly visible to users, but they quietly influence the reliability, flexibility and fairness of the technologies we use every day.

When standards are open, users have more control and choice and experience fewer surprises. And in the long run, these are significant advantages.

The Future of Open Standards and the Importance of ODF

Open standards don’t make headlines. Instead, they work quietly behind the scenes to define how information is created, shared and stored. However, as digital ecosystems become more complex and centralised, open standards are becoming increasingly important.

One of the best examples is the Open Document Format (ODF), the native format of LibreOffice documents.

Open standards in the evolving digital world

The current digital environment is characterised by certain trends, such as cloud platforms, subscription software, artificial intelligence-based tools, and tightly integrated ecosystems. While these tools are powerful, they also increase the lock-in effect exerted by Big Tech.

Open standards act as a counterbalance. They provide shared rules that anyone can implement to maintain system interoperability and user control. When a format is open, no single company can decide how information is stored or who has access to it.

With ever-increasing data volumes and documents being transformed into long-term digital archives, this independence is becoming critical.

ODF was designed with one simple goal: to enable users to read and edit documents on any platform and with any software at any time. This goal is still absolutely valid today.

Because ODF is openly specified and standardised, it allows for the coexistence of multiple tools. LibreOffice and other editors can all work with the same files. Even proprietary software can support ODF without facing legal barriers.

Looking to the future, this aspect is more important than ever. Documents are now inputs for automated workflows, archives for public documents and sources for analysis with artificial intelligence tools, not just files on a desktop. Open formats enable these uses without any constraints.

Government, politics and long-term access

The future of ODF looks particularly secure in the public sector.

Governments are responsible for documents that must remain accessible for decades. Using proprietary formats carries risks in this context: companies change strategy, products are withdrawn from the market (Windows 10 docet), and licences evolve. Open standards reduce this risk.

Since digital sovereignty and transparency are political priorities, ODF is perfectly aligned with these objectives, as it enables public institutions to choose their software freely and maintain consistent access to all data.

ODF in the era of cloud computing and artificial intelligence

Contrary to popular belief, standard and open document formats remain highly relevant in an era of cloud computing and artificial intelligence.

Cloud platforms store documents in the format chosen by the user. If the format is open, users can move, analyse, edit and reuse data across different systems. The XML-based structure of ODF files makes processing documents at the development level easier, which is a key aspect of automation and AI-based workflows.

Since artificial intelligence tools rely heavily on existing documents for training, summarisation and decision support, transparent formats offer a practical advantage as well as a philosophical one.

Future challenges

Open standards are not without their challenges. They require ongoing governance (responsibility of ODF Technical Committee), consistent implementation across tools (which is lacking, because of the strategy of proprietary and open core software, which are pushing users towards proprietary formats against the user’s own interests) and widespread adoption (which has not yet been achieved for the aforementioned reason). Users favour default choices, which are often proprietary, for convenience and lack of expertise.

The future of ODF, and of open standards more generally, depends on continued support from institutions, developers, and users who value openness, even when it is less visible.

Why the future favours open standards

The long-term trend is clear. As digital systems become more powerful, the cost of lock-in grows with them. Open standards offer a way to share innovation without giving up control.

ODF may not be flashy, but it represents a lasting idea: that documents belong to the people who create them rather than the software they use. In the future of open standards, this idea will be more important than ever.

The importance of ODF during the festive season

To be honest, I didn’t think I would publish my usual post about ODF over the festive period, as most people are busy with other activities and the document format isn’t a priority. Those who work are focused on the end of the quarter, while those who don’t work are focused on end-of-year celebrations.

However, I then decided to write this post to highlight the importance of ODF during busy periods such as the festive season. After all, document format is always relevant. Using a proprietary format could mean handing over the moments we share with our families or the sales data we have worked so hard to achieve over the previous 12 months to others.

Families organise gatherings, communities organise events, schools prepare holiday programmes and offices compile reports, schedules and shared documents. Everyone collaborates, often under pressure and almost always using different tools and devices.

It is at times like these that the Open Document Format, or ODF, quietly proves its worth.

Holidays are based on shared documents

Behind every celebration is a surprising amount of paperwork.

There are invitations, programmes, menus, budgets, volunteer lists, seating plans and announcements. These documents are shared with relatives, suppliers, communities, and colleagues. Not everyone uses the same software. In fact, not everyone even uses the same operating system.

ODF simplifies all of this because it is an open standard, enabling documents to be opened, edited and shared across different systems and applications without the risk of file corruption. You send a file and the recipient can open it every time without any problems or worries. That’s it.

During the festive season, this simplicity is more important than advanced features.

There’s no time to ask “Can you send it again?”

Festive season planning often takes place late at night or in between other commitments. People don’t have time to solve format-related problems, but they still want to maintain control over the content.

Documents in proprietary formats can cause problems at the worst possible moment and, in any case, do not allow complete control over the content: fonts change, layouts break and comments disappear. Someone asks for a PDF, and then another version is produced that cannot be edited. This creates confusion.

ODF eliminates these problems because it keeps content readable and editable, regardless of the operating system or tool used. This allows people to focus on the event itself, rather than spending time fixing documents.

When people are juggling travel, family and deadlines, having fewer document-related headaches can make all the difference.

Inclusion depends on open formats

Holidays are about bringing people together, including those who use older devices or assistive technologies due to age or lack of interest in technology. Not to mention those who consciously choose to use free and open-source software.

ODF supports all types of inclusion.

In fact, an open standard enables accessibility tools to function reliably, meaning communities are not forced to purchase specific software just to read a programme or complete a form. Public institutions can share any document without excluding anyone.

If an event is designed for everyone, the related documents should be too.

Holiday documents are important on the long term

Programmes become memories, community reports become archives, and photos and articles are reused year after year. Even family recipes and traditions are passed down in the form of documents.

ODF helps preserve these memories.

The open format means that documents can be read years later, regardless of a company’s commercial decisions to abandon a product because it is not generating enough profit. Years later, documents can be opened, copied and shared.

Holidays are fleeting, but documents should not be.

Public events need public standards

Many holidays are organised by schools, local authorities, cultural groups, and non-profit organisations. These organisations serve the public and use public funds. ODF enables the characteristics of these events to be preserved and protects resources from commercial interests.

Using an open standard avoids being tied to a single supplier, allows for predictable costs, and guarantees transparent access to content without barriers. Community newsletters, holiday calendars and funding forms shared in ODF format respect the diversity of tools used by users.

Open standards align with public values, particularly when information sharing is paramount.

A small choice with a big impact

Choosing the standard and open ODF format may seem like a technical detail. For those who stubbornly refuse to understand everything behind a closed and proprietary format, choosing the standard, open ODF format may even seem like an unnecessary imposition. During the festive season, however, it is a choice with a significant cultural and social impact.

It means the difference between smooth collaboration and last-minute stress; transparent inclusion and seemingly accidental, but actually highly deliberate, exclusion; and documents that last and documents that disappear.

ODF does not require attention and does not interrupt the celebrations. It works very simply in the background, allowing people to focus on what matters: being together, sharing time, and creating memories.

Those who think all this is a sterile marketing exercise could do something useful for themselves and their community by considering the end of support for Windows 10 and older versions of Office. These have rendered many perfectly functioning PCs and readable documents obsolete, despite a user licence having been paid for them. Users should draw the appropriate conclusions from this.

Happy 2026 to everyone under the banner of free and open-source software and the only open standard, which defend our personal freedom from the interference of Big Tech and the governments that support them.

The Role of ODF in the Era of Digital Identity and Authentication

Digital identity has become an integral part of everyday life. We use it to access work tools and sign documents online, and it is even replacing physical identity cards. However, most discussions on the subject focus on authentication systems, encryption and biometrics, ignoring the formats that actually carry our information.

This is where the OpenDocument Format (ODF) quietly becomes important. At first glance, ODF appears to be a straightforward alternative to proprietary formats. However, its features give it a broader role in an increasingly digital world based on identity and trust.

ODF files can be read by users because they use a standard version of the XML schema, are well documented, and are free from any constraints. This transparency is essential when documents become part of identity-related workflows.

In most systems, identity is not just a login, but a collection of artefacts such as contracts, certificates, licences, registrations and evidence. These artefacts often exist in document form: for example, a signed agreement can represent authorisation, a certificate can establish credentials and a form can activate access.

When documents play this role, the format is important because if it is opaque, closed or controlled by a single vendor — the OOXML format has all these characteristics — it cannot guarantee long-term trust. ODF, on the other hand, is transparent, open, predictable and verifiable, and is developed by a consortium of companies. Anyone can verify how documents are structured, how metadata is stored and how signatures are applied.

Modern authentication goes beyond usernames and passwords to include digital signatures, document-level permissions, and audit trails. ODF supports all these elements practically: digital signatures can be embedded in ODF files, metadata can capture authorship, timestamps, and revision history, and version tracking can establish who changed what and when.

Because the format is open, these features can be independently validated. There is no need to trust a ‘black box’ to confirm whether a document is authentic or altered.

Furthermore, digital identity systems rarely exist in isolation. Governments, businesses and individuals use different platforms. Interoperability is not an option, but a requirement.

The open ODF standard facilitates the exchange of documents between identity systems without compromising trust. Documents created in one system can be verified in another without losing their structure or meaning. This is important for cross-border use cases, public sector documents, and long-term archives, where documents may need to be validated decades later.

Identity does not always equate to real-time access. Will the document still be accessible in 20 years’ time? Will its signature still be verifiable? Will its content still be controllable?

ODF was designed with longevity in mind. Because it is not tied to the strategies of any single company, it is particularly well suited to documents that need to outlive specific software products or authentication platforms. For digital identity, this durability is a subtle yet fundamental advantage.

Therefore, ODF does not replace authentication systems, identity providers or cryptographic protocols. That is not its purpose. Rather, ODF is a reliable container; a means of storing, exchanging and preserving identity-related documents without introducing unnecessary risks or dependencies.

In an ideal digital identity stack, ODF operates silently in the background to determine how trust is built and maintained. In the era of digital identity and authentication, this makes ODF more relevant than ever.
