搭建Jena Fuseki并执行SPARQL查询

Posted 2020-11-10 致林

1. 下载Jena Fuseki：http://jena.apache.org/download/index.cgi

2. 运行服务

windows解压后双击fuseki-server.bat
linux解压后运行命令

java -jar fuseki-server.jar --update --loc /data/apache-jena-fuseki-3.5.0/run/databases/DB /ds  

“–update”表示允许修改；“–loc”后面的参数，表示存放Fuseki数据的文件夹路径； “/ds”表示Fuseki服务的名字
程序启动后默认在3030端口运行，http://localhost:3030

3. 导入rdf文件

新建test.rdf，复制以下内容

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:vCard="http://www.w3.org/2001/vcard-rdf/3.0#">
  <rdf:Description rdf:about="http://somewhere/MattJones/">
    <vCard:FN>Matt Jones</vCard:FN>
      <vCard:N rdf:parseType="Resource">
        <vCard:Family>Jones</vCard:Family>
        <vCard:Given>Matthew</vCard:Given>
      </vCard:N>
  </rdf:Description>
  <rdf:Description rdf:about="http://somewhere/RebeccaSmith/">
    <vCard:FN>Becky Smith</vCard:FN>
    <vCard:N rdf:parseType="Resource">
      <vCard:Family>Smith</vCard:Family>
      <vCard:Given>Rebecca</vCard:Given>
    </vCard:N>
  </rdf:Description>
  <rdf:Description rdf:about="http://somewhere/JohnSmith/">
    <vCard:FN>John Smith</vCard:FN>
    <vCard:N rdf:parseType="Resource">
      <vCard:Family>Smith</vCard:Family>
      <vCard:Given>Jones</vCard:Given>
    </vCard:N>
  </rdf:Description>
  <rdf:Description rdf:about="http://somewhere/SarahJones/">
    <vCard:FN>Sarah Jones</vCard:FN>
    <vCard:N rdf:parseType="Resource">
      <vCard:Family>Jones</vCard:Family>
      <vCard:Given>Sarah</vCard:Given>
    </vCard:N>
  </rdf:Description>
</rdf:RDF>

在fuseki界面新建database，并导入以上xml，

3. 执行SPARQL查询

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

SELECT ?x

WHERE { ?x  <http://www.w3.org/2001/vcard-rdf/3.0#FN>  "John Smith" }
