Best practices for creating and editing Open Document Format (ODF) files

Adhering to these guidelines can enhance productivity and guarantee that documents remain consistent, robust and accessible over time, irrespective of the platform. Firstly, use an editor such as LibreOffice that natively supports the format without conversion. This preserves the nuances of the ODF XML structure, supports all its features and reduces the risk of formatting issues or data loss. It also ensures that documents are fully compatible with the ISO standard. Secondly, use an up-to-date version of LibreOffice to benefit from continuous improvements in ODF feature management, avoid bugs that could cause file corruption (a rare event thanks to the robustness of the ODF format, but still possible) and enjoy the highest level of security in file management. Thirdly, use LibreOffice document templates and styles for all elements, such as headings, fonts, paragraphs, and tables, to ensure consistent formatting throughout the document. This allows you to make global changes quickly by changing the style rather than each individual element, and improves accessibility, as screen readers and other assistive technologies rely on a consistent structure. This also results in smaller, more robust ODF files. Creating and reusing LibreOffice templates is an excellent practice for companies that produce many similar documents (such

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,

The Document Foundation announces LibreOffice 25.2.5

LibreOffice 24.8 has now reached the end of life, so all users have to update their free office suite to the latest release Berlin, 17 July 2025 – The Document Foundation announces the release of LibreOffice 25.2.5, the fifth maintenance release of the LibreOffice 25.2 family for Windows (Intel, AMD and ARM), macOS (Apple Silicon and Intel) and Linux OSs, available for download at www.libreoffice.org/download [1]. LibreOffice 24.8 has reached the end of life, which means that this release – which includes dozen of fixes and enhancements that further improve reliability, performance and interoperability – is suggested for production environments, and all users should update their installation as soon as possible. LibreOffice 25.2.5 is based on the LibreOffice Technology, which enables the development of desktop, mobile and cloud versions – either from TDF or from the ecosystem – that fully support the two ISO standards for document formats: the open ODF or Open Document Format (ODT, ODS and ODP) and the closed and proprietary Microsoft OOXML (DOCX, XLSX and PPTX). Products based on the LibreOffice Technology are available for all major desktop operating systems (Windows, macOS, Linux and ChromeOS), mobile platforms (Android and iOS) and the cloud. For enterprise-class deployments,

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.

The end of Windows 10 is approaching, so it’s time to consider Linux and LibreOffice

The Document Foundation and LibreOffice support the international campaign @endof10 https://endof10.org/ The countdown has begun. On 14 October 2025, Microsoft will end support for Windows 10. This will leave millions of users and organisations with a difficult choice: should they upgrade to Windows 11, or completely rethink their work environment? The good news? You don’t have to follow Microsoft’s upgrade path. There is a better option that puts control back in the hands of users, institutions, and public bodies: Linux and LibreOffice. Together, these two programmes offer a powerful, privacy-friendly and future-proof alternative to the Windows + Microsoft 365 ecosystem. The real costs of switching to Windows 11 The move to Windows 11 isn’t just about security updates. It increases dependence on Microsoft through aggressive cloud integration, forcing users to adopt Microsoft accounts and services. It also leads to higher costs due to subscription and licensing models, and reduces control over how your computer works and how your data is managed. Furthermore, new hardware requirements will render millions of perfectly good PCs obsolete. This is a turning point. It is not just a milestone in a product’s life cycle. It is a crossroads. The new path: Linux + LibreOffice These
