cardinality: means exactly 1
<owl:cardinality rdf:datatype= 
"http://www.w3.org/2001/XMLSchema#nonNegativeInteger" >1</owl:cardinality>
maxCardinality: no more than 1
<owl:maxCardinality rdf:datatype= 
"http://www.w3.org/2001/XMLSchema#nonNegativeInteger" 
 >1</owl:maxCardinality>
minCardinality:atleast 1
<owl:minCardinality rdf:datatype= 
"http://www.w3.org/2001/XMLSchema#nonNegativeInteger" 
 >1</owl:minCardinality>
