Attica is a Qt library that implements the Open Collaboration Services
API version 1.4. The REST API is defined here:
 http://www.freedesktop.org/wiki/Specifications/open-collaboration-services

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.
