将fuseki配置配置到内存中，但推理机不起作用 [英] fuseki config to an in memory with reasoner not working

问题描述

这些设置适用于fuseki 2.0，现在我使用的是fuseki 2.3，但这些设置不再起作用:

These settings were working with fuseki 2.0, now i am on fuseki 2.3, but these settings not working any more:

[] 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:

我可以为您提供任何其他信息，请检查我的设置为何不起作用.我想在内存中有一个数据集，该数据集可以从文件

I can give you any other info you want, could you check please why my settings not working. i want to have a dataset in memory, that loads its tribles from a file

推荐答案

此配置唯一可以找到的问题是文件的引用方式(应为file://).下面是一个完整的配置，包括前缀，可在Fuseki 2.5.0中使用.为了清楚起见，我将测试数据和本体放置在单独的文件中.

The only issue I could find with this config was how the file is referenced (should be file://). Below is a complete config, including prefixes, which works in Fuseki 2.5.0. I placed the test data and the ontology in separate files for clarity.

@prefix tdb:   <http://jena.hpl.hp.com/2008/tdb#> .
@prefix rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix ja:    <http://jena.hpl.hp.com/2005/11/Assembler#> .
@prefix rdfs:  <http://www.w3.org/2000/01/rdf-schema#> .
@prefix fuseki: <http://jena.apache.org/fuseki#> .

[] 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://my/data/dir/data.ttl> ];
    ja:content  [ja:externalContent <file://my/data/dir/model.ttl> ];
