What is nepomukservices ?

[Antonio Olivares]

I see the following: 

nepomukservices[3755]: segfault at 4 ip 041878a2 sp bff70360 error 4 in

I hate answers like this.  This answer is just as useful as answering the question of
"where are we" with "in a car."  A http://justfuckinggoogleit.com/ 
would have been more helpful.  

When I googled for it, I found a couple of other links:

http://nepomuk.semanticdesktop.org/xwiki/bin/view/Main1/
http://en.wikipedia.org/wiki/NEPOMUK_(framework)

But they still didn't answer the question that I wanted to know: Should I run it? 
What's it good for?  What can I actually do with it today?  After 5 minutes of
reading, I came to the conclusion, that whatever benefit it might bring in the future
might be great, but I couldn't see it do anything except consume resources.  

I turned it off.

This is probably accurate.

I know a bit about Nepomuk because a lot of development is being done by
Mandriva, where I worked before. It's basically a big ambitious metadata
project for KDE 4, the intention being to use the metadata concept
throughout the KDE desktop for all sorts of things. At present it's at
that state where there's a lot of work done on the back end but very
little at the front end - I think you can use it for basic 'add a tag to
this file' and 'rate this file' in a couple of apps, but that's more or
less it.

It may have changed a bit in KDE 4, I haven't kept up to date with it,
but AFAIK that was the status as of 4.1. Do correct me if I'm wrong :)

I think that's still largely true.  It has great potential, but it's got a
way 
to go.

Exactly! :)

I use both GNOME and KDE and I noticed that while using KDE the CPU was also hovering at
100% I was thinking that the bug

https://bugzilla.redhat.com/show_bug.cgi?id=484054

had also hit KDE, but it was this new service nepomukservices that was hogging the CPU.  I
had never heard of it or its intentions and therefore I had to ask.  Thanks to all user
who have answered my question.

Antonio
