ODF 1.4 Launch Celebrates Two Decades of OpenDocument Standard Enhancements

ODF 1.4 marks a milestone in the OpenDocument Format’s history, celebrating its 20th anniversary under the OASIS Open umbrella. The release introduces several interoperability and accessibility improvements, with contributions from major players such as Collabora, The Document Foundation, IBM, Nokia, KDE, and LibreOffice community members. Key upgrades include the ability to place tables inside shapes, bridging gaps with other formats like Microsoft OOXML, and enhancing cross-format workflows. Accessibility receives a boost through decorative object marking, allowing screen readers to skip decorative images and shapes to reduce clutter for assistive technologies. The update also adds an overlap prevention property to better manage layout, enabling anchored objects to avoid overlapping other elements. Text direction support has been expanded to accommodate a 90-degree counter-clockwise rotation, enabling content to flow from left-to-right and then top-to-bottom in this rotated orientation, complementing existing support for Japanese text layouts. Michael Stahl from Collabora Productivity highlighted that the work over four years since ODF 1.3 aimed to align ODF with current expectations rather than introducing entirely new features. The full ODF 1.4 specification is documented in four parts on the OASIS Open site, covering introduction, packaging, XML schemas, and the formula language for spreadsheets. The article also notes ongoing discussions and examples of how this standard is evolving to improve interoperability across office suites.
