Hi Samuel,

It's probably the same thing as the other time. The data has the label as a typed literal with datatype xsd:string -- in SPARQL this is represented lexically as:

"bifinhos com cogumelos"^^xsd:string

If you change your query to that, I expect you'd get results with both protege and jena. What's happening apparently here is that Jena is adhering to the precise semantics of SPARQL while protege is being a bit lax.

I'm missing any other Prefix?

SELECT ?class
WHERE { ?class rdf:type owl:Class .
?class rdfs:label "bifinhos com cogumelos" }

the class that have that label is this <owl:Class rdf:about="#BifinhosComCogumelos">
    <rdfs:subClassOf>
      <owl:Restriction>
        <owl:someValuesFrom rdf:resource="#Ovo"/>

    <rdfs:subClassOf rdf:resource="#PratosdeCarne"/>
    <rdfs:label rdf:datatype="http://www.w3.org/2001/XMLSchema#string";
    >bifinhos com cogumelos</rdfs:label>
  </owl:Class>

Any ideias of whats wrong this time? Is there another way of do this query?
