No. It will not. There is no way this can be ported. It will need to be 
dropped and rewritten. However, given that Amarok still works perfectly 
without it, It's not going to break anything.

No. I should probably talk to the Digikam guys.

Ported. See feature/baloo branch in kde-baseapps.

Will be ported.

Not going to be ported. Will require massive changes. The maintainer Jorg was 
contacted before the Baloo announcement, and he's happy to move away from 
Nepomuk to something else.

Can't say.

I think Alex and Aleix can make sure this is ported.

Can't say. They are probably just using tags.

WebMiner and Conquiere have been both done by the same awesome guy - Jorg. His 
architecture will allow him to easily move away from Nepomuk. Though we still 
have to talk on how we're going to integrate it will Baloo (and if it is

They can continue to ship Nepomuk, and make sure it is enabled.

No. They will not loose data.

Then lets merge Baloo ASAP and get started with testing. Currently, it's just 
me and a hand full of others. If required we can sit and write testing guides, 
coordinate with the quality team, run blog posts asking for testers, etc. But 
that won't happen untill Baloo moves to SC because in order to test Baloo you 
need to test applications that use Baloo.
