Querying Wikipedia from Pharo

Hernán Morales Durand announced a new fun library with which we can query wikipedia.

Some examples follow:

1) Retrieve in JSON movies from the beautiful Julianne Moore:

| jsonResults |
jsonResults := DBPediaSearch new
        timeout: 5000;
        query: 'SELECT DISTINCT ?filmName WHERE {
  ?film foaf:name ?filmName .
  ?film dbpedia-owl:starring ?actress .
  ?actress foaf:name ?name.
  FILTER(contains(?name, "Julianne"))
  FILTER(contains(?name, "Moore"))

To actually get only the titles using NeoJSON:

((((NeoJSONReader fromString: jsonResults) at: #results) at: #bindings)
    collect: [ : entry | entry at: #filmName ]) collect: [ : movie | movie
at: #value ]

2) Retrieve in XML which genre plays those crazy Dream Theater guys  :

DBPediaSearch new
        timeout: 5000;
        query: 'SELECT DISTINCT ?genreLabel
    ?resource dbpprop:genre ?genre.
    ?resource rdfs:label "Dream Theater"@en.
    ?genre rdfs:label ?genreLabel
    FILTER (lang(?genreLabel)="en")
 LIMIT 100';

More examples are available in DBPediaSearch class side. You can install it
from the Configuration Browser.
