Models.isomorphic介绍

[英]Compares two RDF models, and returns true if they consist of isomorphic graphs and the isomorphic graph identifiers map 1:1 to each other. RDF graphs are isomorphic graphs if statements from one graphs can be mapped 1:1 on to statements in the other graphs. In this mapping, blank nodes are not considered mapped when having an identical internal id, but are mapped from one graph to the other by looking at the statements in which the blank nodes occur. A Model can consist of more than one graph (denoted by context identifiers). Two models are considered isomorphic if for each of the graphs in one model, an isomorphic graph exists in the other model, and the context identifiers of these graphs are either identical or (in the case of blank nodes) map 1:1 on each other.
[中]比较两个RDF模型，如果它们由同构图组成，并且同构图标识符相互映射为1:1，则返回true。如果一个图中的语句可以1:1映射到另一个图中的语句，那么RDF图就是同构图。在这种映射中，当具有相同的内部ID时，不考虑空白节点，而是通过查看出现空白节点的语句从一个图映射到另一个图。一个模型可以由多个图（由上下文标识符表示）组成。如果对于一个模型中的每个图，另一个模型中存在一个同构图，并且这些图的上下文标识符相同，或者（在空白节点的情况下）相互映射1:1，则两个模型被视为同构。
