SPARQL DbPedia foaf:name

Question

Trying to execute some queries but when searching for foaf:name resultset is empty. Here's my code:

SELECT DISTINCT ?uri ?string 
WHERE {
    ?uri rdf:type ?x.       
        ?uri foaf:name 'Cavallo domestico'@it   .
        OPTIONAL { ?uri rdfs:label ?string . FILTER (lang(?string) = 'it') }
}

page exist http://it.dbpedia.org/resource/Equus_caballus/html

Apparently seems it's not related with languages different than english but with foaf:name request. If I execute following, retrieving generic foaf:givenName, it works:

SELECT DISTINCT ?uri ?string 
WHERE {
    ?uri rdf:type ?x.       
        ?uri foaf:givenName 'Jimmy'@en   .
        OPTIONAL { ?uri rdfs:label ?string . FILTER (lang(?string) = 'en') }
}

Did you run this against http://it.dbpedia.org/sparql ? It works for me. — Joe, Nov 17 '15 at 11:10

which one? the first, the second or both? First query returns no results if run in http://dbpedia.org/snorql/. If run in it.dbpedia.org/sparql , as you suggest, it works..... — RobMor, Nov 17 '15 at 11:23
@Joe I'm not sure it's a duplicate anymore. When I look at the Horse entry on DBpedia, I only see one rdfs:label, now. When I pull down the corresponding NTriples, I *do* get all the labels, but I don't seem them on dbpedia.org/sparql when I query for rdfs:label. — Joshua Taylor, Nov 17 '15 at 13:20
@JoshuaTaylor When I run the query [click](http://bit.ly/1S4zD5v) I get all labels from dbpedia.org/sparql . — UninformedUser, Nov 18 '15 at 18:15
@AKSW Yup, it's definitely there. I'm pretty sure it wasn't showing up when I did that search, but maybe I had a typo or something. — Joshua Taylor, Nov 18 '15 at 18:55

I think this wasn't working when I first mentioned that it didn't in a comment, but, as AKSW points out, this seems to be working now. The rdfs:label property has the article titles in various languages, not the foaf:name, so you can do this to get the types of Horse:

select ?x ?type {
  ?x a ?type ;
     rdfs:label "Equus caballus"@it
}
