You don't need an encoded IRI. You need <http://sws.geonames.org/226074/ <http://sws.geonames.org/2378080/>> . rr:predicateObjectMap [ rr:predicateMap [ rr:constant sio:SIO_000664 ] ; rr:objectMap [ rr:termType rr:IRI ; rr:constant gn:Feature; rr:template "{Country_geo}" ]; ] should be producing <http://sws.geonames.org/226074/ <http://sws.geonames.org/2378080/>>, not "http://sws.geonames.org/226074/ <http://sws.geonames.org/2378080/>" . We'll try to make time to simulate this if my response still doesn't get you over this problem.
