我正在使用GraphDB来存储我的三元组,并且需要在 GraphDB 上堆叠SpinSail组件以支持Spin 规则以及GraphDB默认支持的所有其他功能。
到目前为止,我已经设法在支持Spin Rules的远程服务器上创建了一个SailRepository(下面有更多详细信息),但它似乎只支持Spin ,并且不支持GraphDB支持的其他功能(例如,查看 Graph、通过文件添加三元组、搜索ETC。)
创建存储库后,配置文件如下所示:
@prefix ms: <http://www.openrdf.org/config/sail/memory#> .
@prefix rep: <http://www.openrdf.org/config/repository#> .
@prefix sail: <http://www.openrdf.org/config/sail#> .
@prefix sr: <http://www.openrdf.org/config/repository/sail#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
<#Test1> a rep:Repository;
rep:repositoryID "Test1";
rep:repositoryImpl [
rep:repositoryType "openrdf:SailRepository";
sr:sailImpl [
sail:delegate [
sail:sailType "openrdf:MemoryStore";
ms:persist true
];
sail:sailType "openrdf:SpinSail"
]
] .
虽然一个普通的配置文件(例如,如果有人通过工作台创建一个存储库)看起来像下面这样:
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix rep: <http://www.openrdf.org/config/repository#> .
@prefix sail: <http://www.openrdf.org/config/sail#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
<#Test> a rep:Repository;
rep:repositoryID "Test";
rep:repositoryImpl [
rep:repositoryType "graphdb:FreeSailRepository";
<http://www.openrdf.org/config/repository/sail#sailImpl> [
<http://www.ontotext.com/trree/owlim#base-URL> "http://example.org/owlim#";
<http://www.ontotext.com/trree/owlim#check-for-inconsistencies> "false";

sail:sailType "graphdb:FreeSail"
]
];
rdfs:label "Test" .
以下代码用于创建存储库。
RemoteRepositoryManager manager = new RemoteRepositoryManager("http://localhost:7200");
manager.init();
String repositoryId = "Test1";
// create a configuration for the SAIL stack
boolean persist = true;
// create a configuration for the SAIL stack
SailImplConfig spinSailConfig = new MemoryStoreConfig(persist);
spinSailConfig = new SpinSailConfig(spinSailConfig);
RepositoryImplConfig repositoryTypeSpec = new SailRepositoryConfig(spinSailConfig);
// create a configuration for the repository implementation
// RepositoryImplConfig repositoryTypeSpec = new SailRepositoryConfig(backendConfig);
RepositoryConfig repConfig = new RepositoryConfig(repositoryId, repositoryTypeSpec);
manager.addRepositoryConfig(repConfig);
创建此存储库后,我可以通过SPARQL部分将以下规则插入其中(通过使用INSERT DATA):
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX sp: <http://spinrdf.org/sp#>
PREFIX spin: <http://spinrdf.org/spin#>
PREFIX ex: <http://example.org/>
INSERT DATA {
ex:Person a rdfs:Class ;
spin:rule [
a sp:Construct ;
sp:text """PREFIX ex: <http://example.org/>
CONSTRUCT { ?this ex:childOf ?parent . }
WHERE { ?parent ex:parentOf ?this . }"""
] . }
然后类似地添加以下语句:
PREFIX ex: <http://example.org/>
INSERT DATA {
ex:John a ex:Father ;
ex:parentOf ex:Lucy .
ex:Lucy a ex:Person .
}
之后通过运行以下查询:
PREFIX ex: <http://example.org/>
SELECT ?child WHERE { ?child ex:childOf ?parent }
我能够确认 Spin 规则已成功执行。
所以我的问题是:
有没有办法创建一个支持 GraphDB 的所有功能的远程存储库,然后在其上堆叠 SpinSail 组件?
