Sample OWL Modelling ProblemsBelow are snippets of OWL code representing class definitions and datatype definitions that include property restrictions and cardinality restrictions. For each OWL snippet described in Turtle code below, provide a description of what the class represents. Do not worry about namespace definitions or any other syntax-related issues.(1: What does the class ‘problem:thisClass’ represent?problem:thisClass rdfs:subClassOf problem:Person; rdfs:subClassOf [ rdf:type owl:Restriction; owl:onProperty problem:attendsUniversity; owl:someValuesFrom [ rdf:type rdfs:Datatype; owl:onDatatype xsd:string; owl:withRestrictions ([xsd:pattern “[A-Za-z]+Texas[A-Za-z]”]) ] ].
