The OpenDocument format (ODF), an abbreviation for the OASIS Open Document Format for Office Applications, is an open and free (excluding maintenance and support) document file format for saving and exchanging editable office documents such as text documents (including memos, reports, and books), spreadsheets, databases, charts, and presentations. This standard was developed by the OASIS industry consortium, based upon the XML-based file format originally created by OpenOffice.org, and ODF was approved as an OASIS standard on May 1, 2005. It became an ISO standard, ISO/IEC 26300, on May 3, 2006, see main article OpenDocument.
