Question

用于提取GND RDF / XML数据中所有“DifferentiatedPerson”的forename，surname，dateOfBirth和placeOfBirth的正确SPARQL查询是什么？（数据主页：http://www.dnb.de/DE/Service/DigitaleDienste/Datendienst/datendienst_node.html）

  </rdf:Description>

我尝试了以下SPARQL（数据存储在Apache Jena TDB中）：

PREFIX gndo: <http://d-nb.info/standards/elementset/gnd#>
SELECT ?forename ?surname ?dateOfBirth ?placeOfBirth
WHERE {
  ?person a gndo:DifferentiatedPerson .
  ?person gndo:forename ?forename .
  ?person gndo:surname ?surname .
  ?person gndo:dateOfBirth ?dateOfBirth .
  ?person gndo:placeOfBirth ?placeOfBirth
}

没有返回任何结果。（因为这是我的第一个SPARQL查询，它可能完全错误......）

Forename和surename通过属性gndo：preferredNameEntityForThePerson和blanknode连接到人，即查询应该类似

PREFIX gndo: <http://d-nb.info/standards/elementset/gnd#>
SELECT ?forename ?surname ?dateOfBirth ?placeOfBirth
WHERE {
  ?person a gndo:DifferentiatedPerson ;
          gndo:dateOfBirth ?dateOfBirth ;
          gndo:placeOfBirth ?placeOfBirth ;
          gndo:preferredNameEntityForThePerson [
                                                gndo:forename ?forename ;
                                                gndo:surname ?surname 
                                               ]
}

Sparql查询GND-RDF
