can someone please point me to the right direction where to start researching ].
i want to read the yast database i dont even know, if the data is persisted in a database ] and save some data to a sesame triple store in rdf.
final goal of my project would be to have a daemon thats logs into different machines gathers the installed rpms and puts the names of the rpms into my triplestore.
YaST covers many aspects of the system configuration, but you seem to want the package management bit. That is handled by libzypp on top of RPM. Just “rpm -qa” might be all that you need. Also see /usr/share/doc/packages/rpm/manual/queryformat .
