Open Document Format

The Open Document Format for Office Applications (ODF), also known as OpenDocument, is a ZIP-compressed XML-based file format for spreadsheets, charts, presentations and word processing documents. It was developed with the aim of providing an open, XML-based file format specification for office applications.

One objective of open formats like OpenDocument is to guarantee long-term access to data without legal or technical barriers, and some governments have come to view open formats as a public policy issue.

The advantages of ODF include: free download, open format, cross-platform, cross-application features, international exchange, long-term preservation and avoidance of version upgrade conflicts. Currently, many government agencies and companies around the world publicly swear to use ODF as an official document exchange and storage standard to avoid loss of important information.

The most common filename extensions used for OpenDocument documents are:
    • .odt and .fodt for word processing (text) documents
    • .ods and .fods for spreadsheets
    • .odp and .fodp for presentations
    • .odg and .fodg for graphics
    • .odf for formulae, mathematical equations
