Not sure I get it, what's the use of this? You assume "user installs it -> is 
fine with requesting metadata for files from online sources", I think. I'm not 
sure what changes between the first and the second run, however.

Maybe after first installation, it makes sense to actually ask the user. I'm 
usually not a huge fan for this, but in the case of possible inadvertend 
privacy breach, it's warranted to be proactive here. I could imagine:

At first run popup comes up, "You've installed online metadata extraction. It 
will collect additional metadata from the web (such as ... and ...), but it 
can reveal files on your disk to third parties. Only enable this for file 
types that do not affect your privacy. If in doubt, disable it. (Links to 
config, metadata extraction should probably have a separate page in the 
Nepomuk KCM.)

I think that makes a lot of sense. Good idea!

Makes sense, lookup for music and video is enabled by default, I suppose?

What's the preferred plugin? Is that a plugin for a specific service, a 
specific resource type, or ...?

Is there any UI for this?

I think this is a very cool feature, and has the possibility to make Nepomuk 
really shine. Your work on it is much appreciated!
