KOffice was a free and open source office and graphics suite developed by KDE for Unix-like and Windows systems. KOffice contains a word processor (KWord), a spreadsheet (KSpread), a presentation program (KPresenter), and a number of other components that varied over the course of its development.
KOffice was superseded by Calligra Suite in KDE. The KDE3 version is maintained by the Trinity Desktop project.
After development began in 1997, two major stable releases of KOffice were published: Version 1.0 in 2000 and 2.0 in 2009. Following internal conflicts, the majority of KOffice developers split off in 2010 – resulting in the creation of Calligra Suite. Two years later, in September 2012, the KOffice.org website went offline. [9] It now redirects to Calligra.org.

Initial work on KOffice development began in 1997, by Reginald Stadlbauer [16] [17] with KPresenter, followed by KWord [18] in 1998.
In 1999, KOffice was cited in testimony in the United States v. Microsoft antitrust trial by then-Microsoft executive Paul Maritz as evidence of competition in the operating system and office suite arena. [19]
The first official release of the KOffice suite was on 23 October 2000, when it was released as part of K Desktop Environment 2.0. [2] Version 1.1 followed in 2001, [20] 1.2 in 2002, [21] 1.3 in 2004, [22] 1.4 in 2005, [23] and 1.5 [24] and 1.6 both in 2006. [25]
KOffice underwent a major transition as part of the release of KDE Software Compilation 4 (SC4). Coinciding with the work on SC4, the KOffice team prepared a major new release – KOffice 2.0 – which used the new KDE Platform 4 libraries. Although version 2.0 was released in 2009, the release was labeled as a “platform release” which was recommended only for testers and developers, rather than production use, since the release was missing key features and applications from the previous stable release series – Kexi, Kivio, and Kugar were not included. [26]
This continued with version 2.1 in November, 2009. Regular end-users requiring a stable environment were still recommended by developers to use the stable 1.6 release series. [27] This version was also ported to Haiku [28] but the port was later not updated for newer KOffice versions.
In May 2010, version 2.2.0 was released and brought an unprecedented number of new features and bugfixes. Kexi was integrated again. Kivio was not migrated. A new framework for effects on shapes and a new import filters for the Microsoft Office Open XML formats used in MS Office 2007 and later was added. [29]
In mid-2010, following disagreements between KWord maintainer Thomas Zander and the other core developers, [30] [31] [32] the KOffice community split into two separate communities, KOffice and Calligra. Following arbitration with the community members several applications were renamed by both communities. [33] KOffice forked the KSpread spreadsheet utility to KCells, also the KPresenter presentation tool to KOffice Showcase, and the Karbon14 drawing tool to KOffice Artwork.
The community split coincided with the move from KDE's Subversion repository to git. The Krita painting application, the Kexi database manager, and dedicated mobile platform GUI files were not migrated into the KOffice git repository. [34] [35] [36]
KOffice 2.3, released 31 December 2010, [37] along with subsequent bugfix releases (2.3.1–2.3.3 [38] ) was still a collaborative effort of both the KOffice and Calligra development teams. [39] Kivio was still not integrated [40]
Beginning with KOffice 2.4 the developers aimed to release new KOffice versions every six months in sync with SC4 releases [41] but KOffice had seen no development activity since mid-March 2012. [42] As of September 2013, Calligra has released 2.4 and 2.5 and 2.6 and 2.7. After two minor commits in August 2012 [43] the koffice.org website was replaced by a placeholder in early September 2012. [9] On 22 October 2012 KDE removed KOffice from their Quality Website Tools. [44]
As of 2014 [update] KOffice was declared unmaintained by KDE. [45] [46]
The last formally released version of KOffice included the following components:
KWord | A word processor with style sheets and frame-support for DTP-style editing of complex layouts. | |
KSpread | A spreadsheet application with multiple sheet support, templates and more than 100 mathematical formulae. | |
KPresenter | A presentation program with image and effect support. | |
Kexi | An integrated data management application, designed as a Microsoft Access or FileMaker competitor. It can be used for designing and implementing databases, inserting and processing data and performing queries. It has limited compatibility with the MS Access file format. | |
Karbon14 | A vector drawing application with a variety of drawing and editing tools – formerly known as Kontour and KIllustrator. [2] | |
Krita | A digital painting program, with some image processing features – formerly known as Krayon and KImageshop. | |
KChart | Integrated report and chart generator. | |
KFormula | An integrated mathematical formula editor. | |
KPlato | A project management application that can create Gantt-style charts. |
KOffice applications were developed using Qt and KDE Platform. All its components are released under free software licenses and use OpenDocument as their native file format when possible. KOffice was released separately from KDE SC 4 and can be downloaded from KDE's FTP server.
KOffice 2 underwent a large overhaul to use the Flake system of components and Pigment color system, as much as possible within applications. KOffice developers planned to share as much infrastructure as possible between applications to reduce bugs and improve the user experience. [47] They also wanted to create an OpenDocument library for use in other KDE applications that will allow developers to easily add support for reading and outputting OpenDocument files to their applications. [48] Automating tasks and extending the suite with custom functionality can be done with D-Bus or with scripting languages like Python, Ruby, and JavaScript. [49]
KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that allow collaborative work on this kind of software. Well-known products include the Plasma Desktop, KDE Frameworks, and a range of cross-platform applications such as Amarok, digiKam, and Krita that are designed to run on Unix and Unix-like operating systems, Microsoft Windows, and Android.
Calligra Suite is a graphic art and office suite by KDE. It is available for desktop PCs, tablet computers, and smartphones. It contains applications for word processing, spreadsheets, presentation, databases, vector graphics, and digital painting.
Calligra Words is a word processor, which is part of Calligra Suite and developed by KDE as free software.
Calligra Sheets is a free software spreadsheet application that is part of Calligra Suite, an integrated graphic art and office suite developed by KDE.
Calligra Stage is a free presentation program that is part of the Calligra Suite, an integrated office suite developed by KDE.
Kontact is a personal information manager and groupware software suite developed by KDE. It supports calendars, contacts, notes, to-do lists, news, and email. It offers a number of inter-changeable graphical UIs all built on top of a common core.
Kexi is a visual database applications creator tool by KDE, designed to fill the gap between spreadsheets and database solutions requiring more sophisticated development. Kexi can be used for designing and implementing databases, data inserting and processing, and performing queries. It is developed within the Calligra project but is released separately.
Krita is a free and open-source raster graphics editor designed primarily for digital art and 2D animation. Originally created for Linux, the software also runs on Windows, macOS, Haiku, Android, and ChromeOS, and features an OpenGL-accelerated canvas, colour management support, an advanced brush engine, non-destructive layers and masks, group-based layer management, vector artwork support, and switchable customisation profiles.
Kugar is a discontinued tool for generating business quality reports for KOffice. The reports can be viewed and printed. It includes a standalone report viewer and a KParts report viewer. The latter means that any K Desktop Environment 3 application can embed the report viewing functionality and that reports can be viewed using the Konqueror browser.
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
A desktop environment is a collection of software designed to give functionality and a certain look and feel to an operating system.
Kross is a scripting framework for KDE Frameworks. Originally Kross was designed for use in KOffice but eventually became the official scripting framework in KDE Software Compilation 4. Kross is designed to provide full scripting power for users of KDE applications, with a language of their own choice; and make it easy for developers targeting the KDE platform to enable their application with support for multiple scripting languages.
Flake or a Vector Shape is a programming library that is used in Calligra Suite and the KOffice 2 series. Flake provides the basic concept of a "shape". To the end user a shape appears as some piece of content such as an image or a text. A shape can be in any form and contain any kind of media since the Shape is responsible for drawing itself. All components of KOffice are being overhauled to use Flake as much as possible.
K Desktop Environment 2 was the second series of releases of the K Desktop Environment. There were three major releases in this series.
Calligra Plan is a project management application that can create Gantt-style charts and is part of Calligra Suite – formerly included with KOffice.
KWord is a deprecated word processor and a desktop publishing application, part of the KOffice suite. It has been obsoleted by Calligra Words of the Calligra Suite.
KDE Frameworks is a collection of libraries and software frameworks readily available to any Qt-based software stacks or applications on multiple operating systems. Featuring frequently needed functionality solutions like hardware integration, file format support, additional graphical control elements, plotting functions, and spell checking, the collection serves as the technological foundation for KDE Plasma and KDE Gear. It is distributed under the GNU Lesser General Public License (LGPL).
The KDE Gear is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule.
KDE Projects are projects maintained by the KDE community, a group of people developing and advocating free software for everyday use, for example KDE Plasma and KDE Frameworks or applications such as Amarok, Krita or Digikam. There are also non-coding projects like designing the Breeze desktop theme and iconset, which is coordinated by KDE's Visual Design Group. Even non-Qt applications like GCompris, which started as a GTK-based application, or web-based projects like WikiToLearn are officially part of KDE.
This version of KOffice is translated to no less than 27 languages.
