<p>Muitas vezes, a aplicação necessita filtrar com o valor de uma variável. No arquivo <a href="sparql_data/vc-db-2.rdf">vc-db-2.rdf</a>, nós adicionamos um campo extra para idade. Idade não é definida no esquema de vcard então tivemos que criar uma nova propriedade para usar neste tutorial. RDF permite a mistura de diferentes definições de informação porque URIs são únicas. Note também que a propriedade info:age é tipada.</p>
<p>Nesse pedaço de dado, nós mostramos o valor tipado.</p>

<p>Como uma linguagem de consulta, SPARQL é orientada a dados de forma que só consulta as informações presentes nos modelos, não há inferência propriamente dita nesta linguagem de consulta. Por acaso, os modelos de Jena são âinteligentesâ quanto a isso, e nos dá a impressão de que certas triplas são criadas sob demanda, incluindo raciocÃnio OWL. SPARQL nada mais faz do que pegar a descrição do que a aplicação quer, na forma de uma consulta, e retornar a informação, na forma de um conjunto de ligações ou grafo RDF.</p>
