With KDE 4.9, Nepomuk moved out out kdelibs into its own repository. KDE libs is required to maintain source compatibility with earlier releases, and therefore we could not just remove the nepomuk components from kdelibs.

A new repository called nepomuk-core was introduced which contains all the main components of nepomuk. This included vasts parts of kdelibs/nepomuk and kde-runtime/nepomuk. Another repository called nepomuk-widgets has also been introduced for 4.10.

Porting to Nepomuk2

Nepomuk2 is predominantly just a namespace change from Nepomuk to Nepomuk2. Additionally, the deprecated components of Nepomuk have been removed. In order to make porting easier, a simple script has been provided -

egrep -lRZ "Nepomuk" . | xargs -0 -l sed -i -e 's/Nepomuk::/Nepomuk2::/g'  
egrep -lRZ "Nepomuk" . | xargs -0 -l sed -i -e 's/#include <Nepomuk\//#include <Nepomuk2\//'
egrep -lRZ "nepomuk" . | xargs -0 -l sed -i -e 's/#include <nepomuk\//#include <nepomuk2\//'
egrep -lRZ "Nepomuk" . | xargs -0 -l sed -i -e 's/namespace Nepomuk/namespace Nepomuk2/g' 
egrep -lRZ "resourceType" . | xargs -0 -l sed -i -e 's/\.resourceType/\.type/g'
egrep -lRZ "resourceUri" . | xargs -0 -l sed -i -e 's/\.resourceUri/\.uri/g'
egrep -lRZ "NEPOMUK_QUERY_LIBRARIES" . | xargs -0 -l sed -i -e 's/${NEPOMUK_QUERY_LIBRARIES}//g'

This script should cover all the source code changes, and most of the cmake changes.
