Looking at the data the definition of the Jizera
river 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 river
flows through Turnov city.
