Today Jimmy Wales, chairman of the Wikimedia Foundation, announced the beginning of a cooperation between Wikimedia and the KDE project at LinuxTag in Karlsruhe, Germany. As the first applications, like the media player amaroK, start to integrate Wikipedia content the idea is to create a webservice API to access the information from Wikimedia projects such as Wikipedia or Wiktionary. There are also plans for a KDE API.
Wikipedia in amaroK
The API would allow KDE applications to easily embed Wikimedia content, data could even be fetched from a local database depending on your online/offline status. First progress can be seen in Knowledge, a Qt 4 based offline reader for Wikipedia.
Jimmy was also searching for people who want to help with the design of this API, so if you want a good API for your application join the efforts!
