What’s new in ODF 1.3 and 1.4

ODF ensures that documents remain accessible, portable, and free from restrictions. Now that version 1.3 has been widely adopted and version 1.4 is on the horizon, it’s time to have a look at the new features and upcoming releases. ODF 1.3: What’s New ODF 1.3 was finalised in January 2021 by OASIS. It introduced a number of long-awaited improvements, particularly in the areas of security, digital signatures, and document integrity. 1. Digital signatures and document security: One of the most significant enhancements in ODF 1.3 was the formal specification for digital signatures: It now supports XAdES (XML Advanced Electronic Signatures). You can sign entire documents, individual parts (e.g. only spreadsheets), or even multiple sections. Improved metadata provides information about who signed, when and under what circumstances. This is a significant development for public administrations and organisations that require reliable document verification. 2. OpenPGP support for encryption ODF 1.3 now offers optional OpenPGP-based encryption in addition to the traditional Blowfish method. Higher cryptographic standards and better integration with tools such as GnuPG are also included. It encourages key-based encryption for personal and business documents. 3. Change management: The format now offers greater granularity for change management. Supports change tracking in tables,

Understanding ODF File Types: .odt, .ods, .odp, and Beyond

If you’ve ever wondered what those .odt, .ods, or .odp files are all about – or if you’ve stumbled across them and weren’t sure what to do – this post is for you. .odt: The Open Document Text File Think of .odt as the open counterpart to .docx. It’s the default file format for LibreOffice Writer. You can use it for everything from a quick grocery list to a dissertation. What’s great about .odt is that it’s built on open standards. That means anyone can build software to read or write it without jumping through legal hoops. It also means you’re not tied to one company’s ecosystem, which is increasingly important when you think about long-term access to your own data. Yes, you can open .odt files in Word – and yes, the formatting usually holds up pretty well. Not perfect, but usable. .ods: Spreadsheets Without Strings Attached Spreadsheets aren’t just for accountants anymore. Whether you’re managing a budget, tracking tasks, or planning a trip, you’re probably using rows and columns for something. .ods is the ODF version of .xlsx, and it’s handled by tools like LibreOffice Calc. If you’re used to Excel, Calc will feel familiar enough. Basic formulas,

A Technical Dive into ODF

To write this article, I went beyond the limits of my technical knowledge, which is that of an advanced user who has studied standard formats and their characteristics in depth, to understand why standard formats – one of the pillars of digital sovereignty – and proprietary formats – their opposite, and one of the biggest obstacles to digital sovereignty – are not perceived as a problem by most PC users, who continue to use Microsoft’s proprietary formats and place the access and availability of their content in the hands of the US company. To try to remedy this problem, I will try to explain as simply as possible, using non-technical language (which may shock developers, but this article is not aimed at them), some technical features of the Open Document Format (ODF), which make it the cornerstone of an open and vendor-independent ecosystem for office documents, defending the digital freedoms of all users and the governance of their content. I will begin by explaining how to unpack an ODF file, which is nothing more than a set of XML files and other files (for images and videos) contained within a ZIP folder, in order to examine its internal components and,

Understanding ODF compliance and interoperability

The Open Document Format (ODF) is an open standard format for office documents, which offers a vendor-independent, royalty-free way to encode text documents, spreadsheets, presentations, and more. However, to realise its potential, it is necessary to understand the concepts of compliance – the degree to which an implementation adheres to ODF specifications – and interoperability – the ability to exchange and view ODF files without loss of fidelity or functionality across different applications and platforms. ODF is an XML-based file format that has been standardised by OASIS and ratified by ISO/IEC 26300. Milestones include: ODF 1.0 (2006): the initial version defining the basic document types: text (.odt), spreadsheet (.ods) and presentation (.odp). ODF 1.1 (2012): updates to formula specifications and accessibility improvements were made, but it was never submitted for standardisation. ODF 1.2 (2015): introduces digital signatures, RDF metadata, and OpenFormula for standardising spreadsheet calculations. ODF 1.3 (2020): an extension of security features, including improvements to encryption and import/export conventions, as well as a clarification of compliance clauses. Each version has strengthened the role of ODF as a universal interchange format, ensuring that documents remain readable and editable in all programs, both now and in the future.

ODF: An Analysis of the Adoption of the Open Document Format

Over the course of its 20-year history, the ODF standard has been adopted, or at least recommended, by numerous supranational bodies and several countries on almost every continent. However, this does not necessarily mean that the ODF standard is used in accordance with these decisions, which are often laws in their own right, as Microsoft’s substantial lobbying and misinformation campaigns aimed at protecting its revenue of around $25 billion generated by the proprietary OOXML format (DOCX, XLSX and PPTX) encourage the use of the latter. This is despite the fact that the disadvantages for national systems, communities of citizens and individuals are very easy to demonstrate: loss of control over content, interoperability problems and dependence on the commercial strategies of a single vendor. The information in this post is based on my research into sources relating to the adoption or recommendations for the use of ODF. I began compiling this collection of documents around 2010 and continue to update it annually. Over the last twelve months, I have also used artificial intelligence in my research, which has helped me find some articles. Unfortunately, formal adoption or recommendation of ODF does not guarantee its actual use in accordance with the law.

ODF and proprietary formats: a comparison

When we create or share a document – whether a simple text, complex spreadsheet or professional presentation – we make a choice that goes far beyond the file extension. This is because the format gives us, or takes away, control over the content. This post compares the Open Document Format (ODF) with proprietary formats such as DOCX, XLSX and PPTX. The comparison is not just about compatibility, but also about freedom, security, costs, transparency, and our long-term digital future. We have already discussed ODF, and we will continue to do so until its 10th anniversary as an ISO/IEC standard in May 2026, because it is the only open standard available to users. We hope that an increasing number of users will understand how important it is for them to use it to have complete and lasting control over the content they have created, i.e. for their digital freedom, rather than for those of us who support it. ODF is the native format of LibreOffice and other programmes that use the LibreOffice Technology platform. These programmes offer the same functionality, flexibility, security, robustness and interoperability as applications that promote proprietary formats, but without the lock-in strategy. Incidentally, even so-called open-source applications
