Hi there,

 

I have just discovered the Linked Data Fragments endpoint.

 

I have the following request:

 

curl \

  --get \

  -H 'Accept: text/turtle' \

  --data-urlencode 'predicate=http://www.w3.org/2000/01/rdf-schema#label' \

  --data-urlencode 'subject=http://www.wikidata.org/entity/Q78' \

  'https://query.wikidata.org/bigdata/ldf'

 

 

This gives me the labels without language annotations. Do I miss something or why are the language tags absent?

 

wd:Q78  rdfs:label  "巴塞爾"^^rdf:langString , "Basilia"^^rdf:langString , "Bazelo"^^rdf:langString , "Базел"^^rdf:langString , "Basel"^^rdf:langString , "Basileia"^^rdf:langString , "바젤"^^rdf:langString , "Bazel"^^rdf:langString , "Bâle"^^rdf:langString , "Bazylea"^^rdf:langString , "Базэль"^^rdf:langString , "בזל"^^rdf:langString , "巴塞"^^rdf:langString , "Basilea"^^rdf:langString , "बासेल"^^rdf:langString , "بازل"^^rdf:langString , "บาเซิล"^^rdf:langString , "ባዝል"^^rdf:langString , "Базель"^^rdf:langString .

 

 

I can do a similar SPARQL query which returns the labels:

 

SELECT *

WHERE

{

  wd:Q78 http://www.w3.org/2000/01/rdf-schema#label ?lang.

  

  BIND(lang(?lang) as ?anno)

}

 

In the docs (https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual#Standalone_service), I found this example:

https://query.wikidata.org/bigdata/ldf?subject=&predicate=http%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23label&object=%22London%22%40en

all triples that have English label "London"

 

Is there a way to get all labels for a certain language without specifying the label string itself? I tried wildcards but it did not work. 

 

Any hint would be highly appreciated!

 

Thanks,

 

Tobias
