OpenOffice.org, commonly known as OOo or OpenOffice, is an open-source application suite whose main components are for word processing, spreadsheets, presentations, graphics, and databases.[6] It is available for a number of different computer operating systems, is distributed as free software and is written using its own GUI toolkit. It supports the ISO/IEC standard OpenDocument Format (ODF) for data interchange as its default file format, as well as Microsoft Office formats among others. As of November 2009, OpenOffice supports over 110 languages.
OpenOffice.org originated as StarOffice, an office suite developed by StarDivision and acquired by Sun Microsystems in August 1999. The source code of the suite was released in July 2000 with the aim of reducing the dominant market share of Microsoft Office by providing a free and open alternative; later versions of StarOffice are based upon OpenOffice.org with additional proprietary components. The OpenOffice.org project is primarily sponsored by Oracle Corporation (initially by Sun Microsystems). Other major corporate contributors include Novell, Red Hat, IBM, Google and others.
