类名称：Triple

Triple介绍

[英]Triples are the basis for RDF statements; they have a subject, predicate, and object field (all nodes) and express the notion that the relationship named by the predicate holds between the subject and the object.
[中]三元组是RDF语句的基础；它们有一个主语、谓语和宾语字段（所有节点），并表示由谓语命名的关系在主语和宾语之间保持的概念。
