GraphDB -来自新的空存储库的推断语句
GraphDB -来自新的空存储库的推断语句
提问于 2020-11-23 03:06:28
我正在用GraphDB运行一些基本的测试，我很惊讶地看到，当创建一个新的存储库时，一些语句似乎已经存在(由GraphDB推断)。
以下是说明这些语句的存储库的摘要：
和sparql查询的结果来列出它们的CONSTRUCT {?s ?p ?o} WHERE {?s ?p ?o .} LIMIT 100

rdfs:Datatype rdfs:subClassOf rdfs:Class .
rdfs:comment rdfs:range rdfs:Literal .
rdfs:label rdfs:range rdfs:Literal .它们似乎反映了对rdf、rdfs和owl词汇表的部分描述，但也包含了来自http://proton.semanticweb.org/protonsys#的一些属性。我试图弄清楚它们是什么，特别是为什么它们默认存在于GraphDB存储库中，但我在GraphDb文档中没有找到这样的信息。
谢谢!

返回的70个三元组是存储库实例化期间选定的默认RDFS Plus (优化)规则集的公理三元组部分。这些不可删除语句的目的是断言明显的基本假设，如：
<rdf:type> <rdf:type> <rdf:Property> (每个rdf:type关系都是一个属性)
它们的唯一目的是确保符合RDFS semantics。您可以通过存储在$GDB_HOME/configs/rules目录中的PIE文件来控制它们。有关更多信息，请查看软件文档：
