fuseki配置到内存中的reasoner不起作用

Question

这些设置在fuseki 2.0上工作，现在我在fuseki 2.3上，但这些设置不再起作用：

[] rdf:type fuseki:Server ;
    fuseki:services (
        <#serviceInMemoryWithReasoner>
    )
.



<#serviceInMemoryWithReasoner> rdf:type fuseki:Service;
    rdfs:label "testdataset";
    fuseki:name "testdataset";
    fuseki:serviceQuery "query";
    fuseki:serviceUpdate "update";
    fuseki:dataset <#datasetServiceInMemoryWithReasoner> ;
.

<#datasetServiceInMemoryWithReasoner> rdf:type ja:RDFDataset;
    ja:defaultGraph <#datasetmodelServiceInMemoryWithReasoner>
.

<#datasetmodelServiceInMemoryWithReasoner>
    ja:reasoner [ ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>];
    ja:content [ja:externalContent <file:ProposalData/1.ttl> ];
.

这是我遇到的错误：

我可以给你任何你想要的其他信息，你能检查一下为什么我的设置不起作用吗？我想在内存中有一个数据集，可以从文件中加载它的三元组

关于这个配置，我能找到的唯一问题是如何引用这个文件(应该是file://)。下面是一个完整的配置，包括前缀，它在Fuseki 2.5.0中工作。为了清楚起见，我将测试数据和本体放在单独的文件中。
