2. Extended relations used for constraints Currently, Constraints express mathematical terms with two operands and one operator. One of these operands is currently implicit (supposed to be a context property from the real life). I propose: (a) Creating a property called leftOperand which can be specified (or omitted) and (b) Adding the following individuals of Operation: AND, OR, NOT. If we want to declare before 2017 in Italy...: ` :c1 a odrl:Constraint ; odrl:operator odrl:lteq ; odrl:dateTime "2016-12-31"^^xsd:date. :c2 a odrl:Constraint ; odrl:operator odrl:eq ; odrl:spatial <http://www.geonames.org/countries/IT/> ` We could now combine them: ` :c3 a odrl:Constraint ; odrl:operator odrl:AND ; odrl:rightOperand :c1; odrl:leftOperand :c2; ` Or: ` :c3 a odrl:Constraint ; odrl:operator odrl:OR ; odrl:rightOperand :c1; odrl:leftOperand :c2; ` Operators do not need to be binary, if we define a property called “operand” instead of “leftOperand” and “rightOperand”. -- GitHub Notification of comment by vroddon Please view or discuss this issue at https://github.com/w3c/poe/issues/63#issuecomment-261247997 using your GitHub account
