Hi Geert, I am not sure about my syntax so, I tried point 6 given in marklogic documentation at " https://developer.marklogic.com/features/semantics/inference-examples"; regarding "Define your own ruleset".
I followed all the steps given in example but in the last step, where it references custom rule; it doesn't return any result. I am using marklogic 8.0.3 on windows 7 machine.
