OASIS OpenDocument/ISO/IEC 26300 File Format (ODF)

The application uses the OpenDocument file format (also known as ODF) as native file format. This means, stores all documents in OpenDocument file format unless the user requests to store them in a different file format.

The OpenDocument file format is developed by a technical committee at OASIS. It further is an approved and published ISO standard (ISO/IEC 26300:2006). The OpenDocument specification is available at the OASIS OpenDocument TC's web page. See for more information on OpenDocument.

Several members of the XML project and other projects are members of the OASIS OpenDocument technical committee, and collaborate there with members from other projects and vendors on the further development of the OpenDocument file format.

The XML project maintains the implementation of the OpenDocument file format in in very close collaboration and with large support of other projects, in particular the application framework, graphical application, spreadsheet and word processing projects. XML File Format
