SPARQL query not returning any data - sparql

Question

I am new to RDF, so it will be very nice if you can help me with this!
I am trying to query the subject of pickles called "Umeboshi"(It is japanese pickles) as follows:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX type: <http://dbpedia.org/class/yago/>
PREFIX prop: <http://dbpedia.org/property/>
PREFIX onto: <http://dbpedia.org/ontology/>
SELECT ?label ?subject
WHERE {
?Thing
rdfs:label ?label;
prop:subject?subject.
FILTER (?label = "Umeboshi")
}
This query doesn't give me any data.
As I don't know where to find available properties I am referring to the Umeboshi page on dbpedia http://live.dbpedia.org/page/Umeboshi.
Thank you very much for your help!

Answer 1

Two things I found:
In the page you give, the label is given in English, but in your query you omit the language.
subject has a different namespace. It is a dcterm concept and not a dbpedia property.
This leads to the following, changed query, which results in three bindings:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX dct: <http://purl.org/dc/terms/>
SELECT ?label ?subject
WHERE {
?Thing
rdfs:label ?label;
dct:subject ?subject.
FILTER (?label = "Umeboshi"#en)
}
