Hi there I want to add some rules to jena. Here is my "act.rules"
*@PREFIX yago: <http://yago-knowledge.org/resource/ <http://yago-knowledge.org/resource/>>.* *[rule1:* *(?x yago:actedIn yago:Boycott_(film)) * *-> * *(?x yago:is yago:Actor)]* then , Jena give me the following error message. Expected '(' at start of clause, found yago: At '@PREFIX yago: ' -------------------------------------------------------------------------- So I add the () to the first line which looks like *(@PREFIX yago: <http://yago-knowledge.org/resource/ <http://yago-knowledge.org/resource/>>.)* *[rule1:* *(?x yago:actedIn yago:Boycott_(film)) * *-> * *(?x yago:is yago:Actor)]* and there is another error message : Unrecognized qname prefix (yago) in rule I can't understand what the error come froe . I just google "jena add rule" and see some example , following their code. Hoping I can have a resolution and understand the problem here. Thanks you.
