For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
KOffice is an integrated office suite based on the KDE libraries. KOffice currently includes KWord, KSpread, KPresenter, KChart, Karbon14, Krita, Kexi, KFormula, Kugar, and Kivio. There are no special mail and news clients included in KOffice, because there are KMail and KNode available for KDE anyway. All KOffice components work together, and you can embed every KOffice component into any other KOffice component. This is realized using the KParts object model.
Linux-Kontor is a project for the development of a free business management software suite. Core components of this suite are the commodities, bookkeeping, accountancy, and inventory management modules. Platform-independence, Internet capabilities, and scalability are the three main design requirements. The developers have decided to use Java and a three-tier client-server architecture. The data is stored in an SQL database.
LowCal is a lightweight Web-based calendar of events. It is designed to allow you to announce events that have already been planned (it's not "groupware" and doesn't do "calendaring") without requiring the installation of PHP or a database backend. Events can be categorized and users can choose to display one, multiple, or all categories. Viewing modes include tabular monthly calendars and plain event lists, with or without details. Recurring events are well-supported using a cron-like syntax. All display is template-based, allowing complete configurability.
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is intended for people people who write and want their writing to look great without tinkering with formatting details, font attributes, or page boundaries. On screen, it looks like any word processor, but it uses the TeX engine for printed output and producing richly cross-referenced PDFs. It is stable and fully featured.
