ODF 1.3 is an OASIS Standard

The Document Foundation is pleased to announce that LibreOffice’s native document format – the OpenDocument Format for Office Applications (ODF) 1.3 – has been approved as OASIS Standard with 14 affirmative consents and no objections. ODF is a free, open XML-based document file format for office applications, to be used for documents containing text, spreadsheets, charts and graphical elements. ODF 1.3 is an update to the international standard Version 1.2, which was approved by the International Organization for Standardization (ISO) as ISO/IEC 26300 (2015).

The OpenDocument Format specifies the characteristics of an open XML-based application-independent and platform-independent digital document file format, as well as the characteristics of software applications which read, write and process such documents. It is applicable to document authoring, editing, viewing, exchange and archiving, including text documents, spreadsheets, presentation graphics, drawings, charts and similar documents commonly used by personal productivity software applications.

The most important new features of ODF 1.3 are digital signatures for documents and OpenPGP-based encryption of XML documents, with improvements in areas such as change tracking and document security, additional details in the description of elements in first pages, text, numbers and charts, and other timely improvements. The development of ODF 1.3 features has been funded by donations to The Document Foundation.

ODF Technical Committee has received 3 Statements of Use from The Document Foundation, CIBlabs GmbH, and Collabora Productivity.

ODF 1.3 Specification can be downloaded from OASIS website.
