OpenOffice.org (OOo), commonly known as OpenOffice, was an open-source office suite. It was an open-sourced version of the earlier StarOffice, which Sun Microsystems acquired in 1999 for internal use. Sun open-sourced the software in July 2000 as a competitor to Microsoft Office,〔〔 releasing version 1.0 on 1 May 2002.〔 In 2011 Oracle Corporation, the then-owner of Sun, announced that it would no longer offer a commercial version of the suite〔 and soon after donated the project to the Apache Foundation.〔 〕 Apache renamed the software Apache OpenOffice. Other active successor projects include LibreOffice and NeoOffice. OpenOffice.org's default file format was the OpenDocument Format (ODF), an ISO/IEC standard, which originated with OpenOffice.org. It could also read a wide variety of other file formats, with particular attention to those from Microsoft Office. OpenOffice.org contained a word processor (Writer), a spreadsheet (Calc), a presentation application (Impress), a drawing application (Draw), a formula editor (Math), and a database management application (Base). OpenOffice.org was primarily developed for Linux, Microsoft Windows and Solaris, and later for OS X, with ports to other operating systems. It was distributed under the GNU Lesser General Public License version 3 (LGPL); early versions were also available under the Sun Industry Standards Source License (SISSL). == History == OpenOffice.org originated as StarOffice, a proprietary office suite developed by German company StarDivision from 1985 on. In August 1999, StarDivision was acquired by Sun Microsystems〔 for US$59.5 million, as it was supposedly cheaper than licensing Microsoft Office for 42,000 staff. On 19 July 2000 at OSCON, Sun Microsystems announced that it would make the source code of StarOffice available for download with the intention of building an open-source development community around the software and of providing a free and open alternative to Microsoft Office.〔 The new project was known as OpenOffice.org, and the code was released as open source on 13 October 2000. The first public preview release was Milestone Build 638c, released in October 2001 (which quickly achieved 1 million downloads); the final release of OpenOffice.org 1.0 was on 1 May 2002.〔 OpenOffice.org became the standard office suite on Linux and spawned many derivative versions. It quickly became noteworthy competition to Microsoft Office, achieving 14% penetration in the large enterprise market by 2004. The OpenOffice.org XML file format – XML in a ZIP archive, easily machine-processable – was intended by Sun to become a standard interchange format for office documents, to replace the different binary formats for each application that had been usual until then. Sun submitted the format to the Organization for the Advancement of Structured Information Standards (OASIS) in 2002 and it was adapted to form the OpenDocument standard in 2005, which was ratified as ISO 26300 in 2006. It was made OpenOffice.org's native format from version 2 on. Many governments and other organisations adopted OpenDocument, particularly given there was a free implementation of it readily available. Development of OpenOffice.org was sponsored primarily by Sun Microsystems, which used the code as the basis for subsequent versions of StarOffice. Developers who wished to contribute code were required to sign a Contributor Agreement〔(【引用サイトリンク】title=Oracle Contributor Agreement )〕 granting joint ownership of any contributions to Sun (and then Oracle), in support of the StarOffice business model. This was controversial for many years.〔 An alternative Public Documentation Licence (PDL)〔(【引用サイトリンク】title=Public Documentation License )〕 was also offered for documentation not intended for inclusion or integration into the project code base.〔(【引用サイトリンク】title=FAQs: Licensing )〕 After acquiring Sun in January 2010, Oracle Corporation continued developing OpenOffice.org and StarOffice, which it renamed Oracle Open Office,〔 though with a reduction in assigned developers. Oracle's lack of activity on or visible commitment to OpenOffice.org had also been noted by industry observers. In September 2010, the majority of outside OpenOffice.org developers left the project, due to concerns over Sun and then Oracle's management of the project and Oracle's handling of its open source portfolio in general, to form The Document Foundation. TDF released the fork LibreOffice in January 2011, which most Linux distributions soon moved to. In April 2011, Oracle stopped development of OpenOffice.org and fired the remaining StarDivision development team.〔 Its reasons for doing so were not disclosed; some speculate that it was due to the loss of mindshare with much of the community moving to LibreOffice while others suggest it was a commercial decision.〔 In June 2011, Oracle contributed the trademarks to the Apache Software Foundation.〔; (Oracle blog version )〕 It also contributed Oracle-owned code to Apache for relicensing under the Apache License, at the suggestion of IBM (to whom Oracle had contractual obligations concerning the code),〔 as IBM did not want the code put under a copyleft license. This code drop formed the basis for the Apache OpenOffice project. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OpenOffice.org」の詳細全文を読む スポンサード リンク
