The only slight problem might be that Dolphin still likes being "Nepomuk Optional" at compile time. So they still use it. Maybe we should talk to Frank about this?

I think we'll keep the "Nepomuk optional for building Dolphin" thing in KDE 4.x. Accoding to feedback I got from users, some people like to build Dolphin with as few dependencies as possible. But for Frameworks, I don't really see a point in it. We'll depend on many different frameworks anyway, so replacing the parts of kdelibs that are needed for KFileMetaDataWidget by nepomuk-core and nepomuk-widgets has hard, non-optional dependencies looks reasonable to me.

But then I wonder why we should even bother to keep KFileMetaDataWidget at all? Shipping code that is unmaintained, even if it is "just" in kde4support, does not look like a good idea to me. Couldn't it just be removed? Porting to Nepomuk's widget is simple enough, and if people feel that this makes porting apps to Frameworks too hard, one could still put a simple header file into kde4support that makes KFileMetaDataWidget a typedef for Nepomuk's widget.
