How to update the RDF triple (not added new one) using jena rule. I am using generic rule reasoner and rules are in separate file as shown case 1:
@prefix fa: http://www.smarthome_haier.com#.
Rule1: (?a fa:setTimer “0”)(?a fa:windvolume “150”)->remove(0)(?a fa:setTimer “1”)
This work fine using remove() Builtin primitive to add new triple and delete the old triple "(?a fa:setTimer “0”)" using remove() builtin option.
But for example in this 2nd case below where we want same result as case one:
@prefix fa: http://www.smarthome_haier.com#.
Rule1: (?a fa:airPresure “40”)(?a fa:windvolume “150”)->(?a fa:setTimer “1”)
Using this adds new triple (?a fa:setTimer “1”) in graph but old triple also exist (?a fa:setTimer “0”) because we are not remove that one.
How can we update triple in 2nd case? Where (?a fa:setTimer “0”) is not present in rule head. I hope this explain this problem. Any help will appreciated. Thanks!
