使用 TDB2 和 OWL Reasoner 配置 fuseki

Question

新來的 fuseki/jena 在這里。 我設法讓 fuseki 使用 tdb1 與 OWLFBRuleReasoner 一起運行沒問題，但不能讓它與 tdb2 ( http://jena.apache.org/2016/tdb# ) 一起使用。 我找不到同時使用 TDB2 和 OWLFBRuleReasoner 的顯式配置示例，所以我只是轉換了這個（有效）

    @prefix :      <http://base/#> .
@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#> .

# fuseki configuration to have OWL entailment
# this is the configuration on s-stf-gin (fuseki data folder is on c:\)

:service_tdb_all  a                   fuseki:Service ;
        rdfs:label                    "TDB gsip" ;
        fuseki:dataset                :tdb_dataset_readwrite ;
        fuseki:name                   "gsip" ; 
        fuseki:serviceQuery           "query" , "sparql" ;
        fuseki:serviceReadGraphStore  "get" ;
        fuseki:serviceReadWriteGraphStore
                "data" ; 
        fuseki:serviceUpdate          "update" ; 
        fuseki:serviceUpload          "upload" . 

        # above, remove data, update and upload in prod
:tdb_dataset_readwrite
        a             ja:RDFDataset;
        rdfs:label "GSIP";
        ja:defaultGraph       <#model_inf> ;
        tdb:location  "c:\\fuseki/databases/gsip" .

<#model_inf> a ja:InfModel ;
     ja:baseModel <#graph> ;
     ja:reasoner [
         ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>
     ] .

<#graph> rdf:type tdb:GraphTDB ;
  tdb:dataset :tdb_dataset_readwrite .

（這個工作正常。我用 owl:inverseOf 屬性進行了測試）

進入這個（不起作用）

@prefix :      <http://base/#> .
@prefix tdb2:   <http://jena.apache.org/2016/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#> .

:service_tdb_all  a                   fuseki:Service ;
        fuseki:dataset                :dataset ;
        fuseki:name                   "gsip" ;
        fuseki:serviceQuery           "query" , "sparql" ;
        fuseki:serviceReadGraphStore  "get" ;
        fuseki:serviceReadWriteGraphStore "data" ;
        fuseki:serviceUpdate          "update" ;
        fuseki:serviceUpload          "upload" .

:dataset a ja:RDFDataset ;
    ja:defaultGraph       <#model_inf> ;
    tdb2:location  "c:\\fuseki/databases/gsip"
     .

<#model_inf> a ja:InfModel ;
     ja:baseModel <#graph> ;
     ja:reasoner [
         ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>
     ] .

<#graph> rdf:type tdb2:GraphTDB ; # also tried tdb2:GraphTDB2
  tdb2:dataset :dataset .

如您所見，我基本上只是將 tdb 替換為 tdb2（命名空間和所有）。 Fuseki 啟動並運行良好，但 OWL 推理不起作用。

任何人都可以指向我相關的文檔/示例？ 或者我可能完全誤解了 TDB1 與 TDB2 的交易。

謝謝你

編輯：修復了我的 TDB2 配置文件（仍然不起作用）。

以下對我有用：

@prefix :      <http://base/#> .
@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#> .

:service_tdb_all  a                   fuseki:Service ;
        rdfs:label                    "TDB [MyDatasetName]" ;
        fuseki:dataset                :inferred_dataset ;
        fuseki:name                   "[MyDatasetName]" ;
        fuseki:serviceQuery           "query" , "sparql" ;
        fuseki:serviceReadGraphStore  "get" ;
        fuseki:serviceReadWriteGraphStore
                "data" ;
        fuseki:serviceUpdate          "update" ;
        fuseki:serviceUpload          "upload" .

:inferred_dataset a ja:RDFDataset ;
        ja:defaultGraph :inference_model .

:inference_model a ja:InfModel ;
        ja:baseModel :tdb_graph ;
        ja:reasoner [
                ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>
        ] .

:tdb_graph a tdb:GraphTDB ;
        tdb:dataset :tdb_dataset_readwrite .

:tdb_dataset_readwrite
        a             tdb:DatasetTDB ;
        tdb:location  "[MyDatasetLocationOnDisk]" .

與您的版本的主要區別是沒有推理的單獨數據集（而不是已經注意到的回送“Barry NL”）和 tdb 前綴的不同命名空間。 請注意，命名空間前綴可以自由選擇（它們沒有語義意義），並且只要指向相同的命名空間 URL，更改命名空間前綴就沒有關系。
