本文整理了Java中org.apache.jena.rdf.model.Model.createProperty()方法的一些代码示例，展示了Model.createProperty()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Model.createProperty()方法的具体详情如下：
包路径：org.apache.jena.rdf.model.Model
类名称：Model
方法名：createProperty

Model.createProperty介绍

[英]Create a property with a given URI composed from a namespace part and a localname part by concatenating the strings.

This method may return an existing property with the correct URI and model, or it may construct a fresh one, as it sees fit.

Subsequent operations on the returned property may modify this model.
[中]通过连接字符串，使用由命名空间部分和localname部分组成的给定URI创建属性。
此方法可以返回具有正确URI和模型的现有属性，也可以根据需要构造新属性。
对返回属性的后续操作可能会修改此模型。
