使用Rowlex从RDF中删除多值属性

Question

我正在尝试从RDF中删除具有多个值的属性，似乎是关于这个RDF，我应该编写以下代码来删除includeResource：

<Ontologyowl:StudyList rdf:about="stdl827181">
        <Ontologyowl:title rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Basic learning materials</Ontologyowl:title>
        <Ontologyowl:includeResource>
            <Ontologyowl:LearningResource rdf:about="res298830"/>
        </Ontologyowl:includeResource>
        <Ontologyowl:includeResource>
            <Ontologyowl:LearningResource rdf:about="res323717"/>
        </Ontologyowl:includeResource>
    </Ontologyowl:StudyList>

StudyList_ stdl = (StudyList_)rdfDoc.GetIndividual(stdlId, StudyList.Uri, false);
LearningResource[] lrnRes = stdl.includeResources;

        foreach (LearningResource i in lrnRes)
        {
            stdl.RemoveincludeResource(i);
            rdfDoc.RemoveProperty(...);
        }

但我现在不了解rdfDoc.RemoveProperty(..)输入。有什么需要帮忙的吗？

RdfDoc.RemoveProperty(主语、谓语、宾语)实际上需要您指定完整的三元组。此方法由您的stdl.RemoveincludeResource(i)方法包装。但是，您的包装方法更易于阅读，而且是类型安全的。宿主C#宾语(RemoveincludeResource)是主语，方法(stdl)表示谓语，输入参数(i)将是宾语。这些项在内部传递给RdfDocument.RemoveProperty方法。不需要同时调用两个方法！
