Quick Valid Question

Here is a quick question…Is the following Rule, valid or not-valid:

    odrl:permission [
        odrl:target :Asset1 ;
        odrl:assignee :Alice ; 
        odrl:action odrl:print ;
        odrl:constraint [ 
            odrl:leftOperand odrl:spatial;
            odrl:operator odrl:eq ;
            odrl:rightOperand “http://vocab.getty.edu/tgn/7353123" ;
        ]
    ] ;

?
