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 like mail, calendar and contacts.
For years, KDE software has included a semantic (relationship-based) searching infrastructure. KDE[he]#039[/he]s Semantic Search was built around concepts previously developed in a European Union-funded research project NEPOMUK which explored the use of relationships between data to improve search results.

Developed as part of KDE4 was Nepomuk to handle meta data of all kinds on the desktop in a generic fashion regardless of file type as a step towards a semantic desktop. While Nepomuk continues to advance, the KDE developers are now collaborating with GNOME developers to bring Zeitgeist to the KDE desktop too.
After updating to Kubuntu 13.04 with KDE 4.10.5 KMail said that the Semantic Desktop isn't running. Nepomik-Semantik-Services and E-Mail-Indexing were already activated, now I also activated File-Indexing. After that KMail runs without the message. But the find-function <strg><f> in Dolphin doesn't work anymore - and I used it very often before, it worked fine.
You have probably heard of Nepomuk, the semantic desktop technology we've been shipping for a while as part of the KDE Platform. However, so far, you may not have noticed it really doing very much useful for you. So what is this thing called Nepomuk, what can it do for us now and what will it bring us in the future?
