     <p>Esta sessão cobre os padrões básicos e as soluções, os principais blocos das consultas SPARQL.</p>
 <h2 id="soluções">Soluções</h2>
 <p>Soluções são um conjunto de pares de variáveis com um valor. Uma consulta <code>SELECT</code> expõe diretamente as soluções (depois de ordenar/limitar/deslocar) como o conjunto resultado – outras formas de consulta usam as soluções para fazer um grafo. Solução é a maneira como o padrão é casado – em que os valores das variáveis são utilizados para casar com o padrão.</p>
 <p>A primeira consulta de exemplo teve uma solução simples. Mude o padrão para esta segunda consulta: (<a href="sparql_data/q-bp1.rq">q-bp1.rq</a>):</p>

 </span></span></span></code></pre></div><p>Até agora, com padrões de triplas e padrões básicos, cada variável será definida em cada solução. As soluções de uma consulta podem ser pensadas como uma tabela, mas no caso geral, é uma tabela onde nem sempre cada linha vai ter um valor para cada coluna. Todas as soluções para uma consulta SPARQL não têm que ter valores para todas as variáveis em todas as soluções como veremos depois.</p>
 <h2 id="padrões-básicos">Padrões Básicos</h2>
 <p>Um padrão básico é um conjunto de padrões de triplas. Ele casa quando todo o padrão da tripla casa com o mesmo valor usado cada vez que a variável com o mesmo nome é usada.</p>
