Question

我有一个脚本，当我在graphdb的本地实例中运行它时。但是当我尝试在https://cloud.ontotext.com/的在线graphdb上使用它时，我得到一个org.eclipse.rdf4j.query.QueryEvaluationException，但没有任何内容表明导致它的脚本的哪个部分。

本地脚本的唯一变化是

SERVICE <https://rdf.ontotext.com/4136450524/pedtermsDB/repositories/pedagogyrepo>{

是

SERVICE <http://localhost:7200/rdf-bridge/1967855032375>{

感谢任何帮助。

您的查询中混合了两种不同类型的SPARQL端点：

GraphDB端点 - 为索引的RDF三元组提供服务的存储库端点：

http://localhost:7200/repositories/repositories/pedagogyrepo - 本地端点
https://rdf.ontotext.com/4136450524/pedtermsDB/repositories/pedagogyrepo - 云端点

OntoRefine端点 - 用于提供OpenRefine内部表格模型的虚拟端点

http://localhost:7200/rdf-bridge/1967855032375 - 本地端点
https：// * rdf-bridge // - 为此项目创建的云端点

您必须通过Workbench界面找到云上正确的OntoRefine端点。

insert query生成QueryEvaluationException
