Note also that an equivalent restriction would be

  ma:Image rdfs:subClassOf [
    a owl:Restriction ;
    owl:onProperty ma:duration ;
    owl:allValuesFrom owl:Nothing

I am not very fond of this pattern, that I find a bit awkward, but I
believe it is acceptable in more OWL dialects than the cardinality
