KDeclarative provides integration of QML and KDE work spaces. It's comprises two parts: a library used by the C++ part of your application to integrate QML with KDE Frameworks specific features, and a series of QML imports that offer bindings to some of the Frameworks.

KActivities provides the infrastructure needed to manage a user's activities, allowing them to switch between tasks, and for applications to update their state to match the user's current activity. This includes a daemon, a library for interacting with that daemon, and plugins for integration with other frameworks.

Breeze provides a freedesktop.org compatible icon theme. It is the default icon theme for the KDE Plasma desktop.

KService provides a plugin framework for handling desktop services. Services can be applications or libraries. They can be bound to MIME types or handled by application specific code.

KDESU provides functionality for building GUI front ends for (password asking) console mode programs. kdesu and kdessh use it to interface with su and ssh respectively.

Attica is a Qt library that implements the Open Collaboration Services API version 1.6.

It grants easy access to the services such as querying information about persons and contents. The library is used in KNewStuff3 as content provider. In order to integrate with KDE's Plasma Desktop, a platform plugin exists in kdebase.

The REST API is defined here: http://freedesktop.org/wiki/Specifications/open-collaboration-services/

This package provides a non-blocking Qt database framework.

KDBusAddons provides convenience classes on top of QtDBus, as well as an API to create KDED modules.

KXMLGUI provides a framework for managing menu and toolbar actions in an abstract way. The actions are configured through a XML description and hooks in the application code. The framework supports merging of multiple descriptions for integrating actions from plugins.

The KDE GUI addons provide utilities for graphical user interfaces in the areas of colors, fonts, text, images, keyboard input.

The plasma framework provides QML components, libplasma and script engines.

The Package framework lets the user install and load packages of non binary content such as scripted extensions or graphic assets, as if they were traditional plugins.

KCoreAddons provides classes built on top of QtCore to perform various tasks such as manipulating mime types, autosaving files, creating backup files, generating random sequences, performing text manipulations such as macro replacement, accessing user information and many more.

Provides tools to generate documentation in various format from DocBook files.

This package provide a Classes to read and interact with KColorScheme.

KUnitConversion provides functions to convert values in different physical units. It supports converting different prefixes (e.g. kilo, mega, giga) as well as converting between different unit systems (e.g. liters, gallons).

KCodecs provide a collection of methods to manipulate strings using various encodings.

It can automatically determine the charset of a string, translate XML entities, validate email addresses, and find encodings by name in a more tolerant way than QTextCodec (useful e.g. for data coming from the Internet).

KWindowSystem provides information about and allows interaction with the windowing system. It provides a high level API, which is windowing system independent and has platform specific implementations. This API is inspired by X11 and thus not all functionality is available on all windowing systems.

In addition to the high level API, this framework also provides several lower level classes for interaction with the X Windowing System.

This package provides Kirigami components usable by both touch and desktop experiences.

This framework offers the possibility to create integrate services and actions on any application without having to implement them specifically. Purpose will offer them mechanisms to list the different alternatives to execute given the requested action type and will facilitate components so that all the plugins can receive all the information they need.

The Quick Charts module provides a set of charts that can be used from QtQuick applications for both simple display of data as well as continuous display of high-volume data.

Kdeinit is a process launcher similar to init used for booting UNIX. It launches processes by forking and then loading a dynamic library which contains a kdemain(…) function. Using kdeinit to launch KDE applications makes starting KDE applications faster and reduces memory consumption.

KDED stands for KDE Daemon. KDED runs in the background and performs a number of small tasks. Some of these tasks are built in, others are started on demand.

Prison is a Qt-based barcode abstraction layer/library and provides uniform access to generation of barcodes with data.
