'''Go-oo''' (previously called '''ooo-build'''<ref>http://slashdot.org/article.pl?sid=07/10/03/1212234</ref>) is a concentrated set of patches for the [[cross-platform]] [[OpenOffice.org]] [[office suite]]. Go-oo is also one of OpenOffice.org variants created from these patches. It has more complete support for [[Office Open XML]] file formats than OpenOffice.org releases produced by [[Oracle Corporation]] (which require the addition of the ODF Converter Integrator extension in order to provide comparable functionality)<ref>{{cite web|url = http://katana.oooninja.com/w/odf-converter-integrator|title = odf-converter-integrator|accessdate = 2010-10-18}}</ref> and other enhancements that have either not yet been accepted into the upstream Oracle version, or will not be because of business or political reasons.{{Citation needed|date=July 2010}} Some of these changes or enhancements may eventually be part of the Oracle version too, given time.{{Citation needed|date=July 2010}}
The hybrid PDF export (PDF that include their original source documents), Sun Presentation Minimizer, and other functionality is directly available in Go-oo.
The OpenOffice.org included with many popular Linux distributions such as [[Debian]], [[Mandriva]], [[openSUSE]], [[Gentoo Linux|Gentoo]]<ref>{{cite web |url = http://packages.gentoo.org/package/app-office/openoffice?full_cat |title=Gentoo's OpenOffice Package}}</ref> and [[Ubuntu (operating system)|Ubuntu]]<ref>{{cite web |url = https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/151829/comments/5 |title=Bug #151829 in openoffice.org (Ubuntu): “Include go-oo in Ubuntu” |work=Chris Cheney, Ubuntu's OpenOffice.org package maintainer |accessdate=2009-01-28}}</ref> uses some of Go-oo patches.<ref name="linux.com">http://www.linux.com/feature/154364</ref><ref name="go-oo-download">[http://go-oo.org/download/ Go-oo derivates in Linux distributions]</ref>
Go-oo, as a variant of [[OpenOffice.org]], supports the [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]] standard [[file format]]s [[OpenDocument]] (full support) and [[Office Open XML]] (read and write) for data interchange, as well as [[Microsoft Office]] 97–2003 formats, among many others.
The Go-oo patches are being incorporated into the [[LibreOffice]] [[Fork (software development)|fork]] of OpenOffice, as of September, 2010, and the Go-oo team have announced that Go-oo will be discontinued in favour of LibreOffice.<ref>{{cite news | url=http://lwn.net/SubscriberLink/407339/006fbb522912ea00/ | title=Michael Meeks talks about LibreOffice and the Document Foundation }}</ref>
