After moving/ renaming a directory (with Dolphin), all tags and other metadata of it's content are gone; When I search for the tags, Nepomuk only finds nonexisting files. I expected this, but how do I fix it (KDE 4.4)? And is there a way to move files without losing tags?

Nepomuk will have improved file watching in KDE 4.5 which will enable it to detect any movement of files within your $HOME directory.

You can use my neposync tool to easily:
- store your tags into files metadata
- move your files
- store files metadata to nepomuk
