OpenDocument Format

An open, XML-based file format standard for office documents maintained by OASIS (Organization for the Advancement of Structured Information Standards). ODF includes specifications for text documents, spreadsheets, presentations, and graphics. It incorporates accessibility features from SVG, including grouping metadata and title elements for describing visual objects, as well as connector elements for describing arrow relationships between objects. ODF is used by applications such as LibreOffice and OpenOffice.org and is an ISO/IEC standard (26300), promoting interoperability and long-term accessibility of office documents.
