OASIS is pleased to announce the publication of its newest OASIS Standard, approved by the members on 27 April 2021:

Open Document Format for Office Applications (OpenDocument) Version 1.3
OASIS Standard
27 April 2021

The OpenDocument Format is a free, open XML-based document file format for office applications, to be used for documents containing text, spreadsheets, charts, and graphical elements. OpenDocument Format v1.3 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). OpenDocument Format v1.3 includes improvements for document security, clarifies under-specified components, and makes other timely improvements.

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 TC received 3 Statements of Use from The Document Foundation, CIBlabs GmbH, and Collabora Productivity.
