Motivation
Looking at the data the definition of the Jizerariver could be like this:<owl:NamedIndividual rdf:about="http://www.sdi4apps.eu/GFO#Jizera">
...<flows_through rdf:resource="http://www.sdi4apps.eu/GFO#Turnov"/>...
</owl:NamedIndividual>
From this it becomes obvious that Jizera riverflows through Turnov city.
