With the currently ongoing split of kdelibs and kde-runtime according to KDE 5.0 frameworks Nepomuk has already partly been reorganized:
kdelibs/nepomuk and most parts of kde-runtime/nepomuk have been moved into the new repository "nepomuk-core". kdelibs master has already been frozen for some time. kde-runtime/nepomuk master is now effectively frozen as development has moved to the new nepomuk-core repository. Shortly new repositories as outlined in [1] will be created to contain the rest of kde-runtime/nepomuk. Cheers, Sebastian [1] http://community.kde.org/Projects/Nepomuk/Irc_meeting_nepomuk_frameworks
