OpenOffice is using the OASIS Open Document Format for Office Applications, which is also supported by a variety of other office applications including StarOffice, KOffice, and IBM Workplace. XFRX generates the file format natively, so OpenOffice doesn’t have to be installed on the computer where the document is generated.
