One of the most disliked features of the early KDE SC 4 releases was the developers' attempt to establish the semantic desktop. The tools to further this goal are Nepomuk and Akonadi. While Nepomuk tries to interconnect meta data from different desktop applications, Akonadi is a service that stores and retrieves data from PIM applications Continue reading...
Nepomuk is the social semantic desktop framework that was largely developed in KDE SC 4 and uses RDF (Resource Description Framework) data storage. The reported cost of developing Nepomuk was reportedly 17 million Euros, after the European Union had invested most of that money into its development for advancing the semantic desktop (update: There's some confusion over the Nepomuk investment and apparently not for the KDE portion). KDE Nepomuk finally reached a mature state in KDE SC 4.11.
In this article, the author brings together the information so far known on the KDE4 "semantic desktop" and indicates that from his perspective, the principal problem is the removal of "choice". Since disabling of the "semantic desktop" automatically leads to disabling of the KDE email client KMail, the article explains how Thunderbird can be installed to replace the KDE email client. The startling news that Nepomuk is to be discarded is also briefly discussed.
I was a loyal and happy KDE 3.x user way back when only dinosaurs used Linux. Then KDE4 came along and my happy KDE world was upended. The first KDE4 release was back in 2008-- how time flies!-- and like so many KDE3 users I had my complaints: Too lardy! Too weird! Where is my stuff?Well, that was then, and here we are five years later. So what does KDE4 look like these days? Is it still lardy and full of weird stuff? I installed Kubuntu 12.10 just to get KDE 4.10 so I could poke at it and see what it's doing.
