OpenOffice.org XML

OpenOffice.org XML is an open XML-based file format developed as an open community effort  by Sun Microsystems in 2000–2002. The open-source software application suite OpenOffice.org 1.x and StarOffice 6 and 7 used the format as their native and default file format for saving files. The OpenOffice.org XML format is no longer widely used, but it is still supported in recent versions of OpenOffice.org-descended software.

OpenDocument (ISO/IEC 26300:2006) is based on OpenOffice.org XML and these formats are very similar in many technical areas. However, OpenDocument is not the same as the older OpenOffice.org XML format and these formats are not directly compatible. In 2005, OpenOffice.org (since version 2.0) and StarOffice (since version 8) switched to OpenDocument as their native and default format.

History
StarOffice developers adopted XML to replace the old binary StarOffice file format. The draft version was also known as StarOffice XML File Format.

The stated goal in the draft was:

File formats
The format uses XML files to describe the documents. To minimize space, the files are compressed into an archive and given a suffix depending on what sort of data is contained in them.
