For those who are unfamiliar with OpenOffice.org, it's a popular cross-platform office application suite that can be used on various operating systems. It supports OpenDocument Format (ODF) as its default file format, which is an ISO standard for data interchange. Additionally, it also supports Microsoft Office '97-2003 formats, among many others.
OpenOffice.org was first derived from StarOffice, an office suite that was developed by StarDivision and later acquired by Sun Microsystems. The source code for the suite was released in July 2000 and aimed to provide an open, free, and high-quality alternative to Microsoft Office, which dominated the market. In the present day, OpenOffice.org remains as free software and is available under GNU Lesser General Public License (LGPL).
The project is informally called OpenOffice, yet due to trademark reasons, it must use the formal name of OpenOffice.org. Overall, OpenOffice.org aims to provide a practical office suite for users that is free, open, and offers high-quality alternatives to established office application suites.
