IfcLibraryInformation

实体定义

IfcLibraryInformation描述了一个库，其中库是结构化的信息存储，通常以允许通过索引或参考值查找信息的方式组织。IfcLibraryInformation提供库名称和可选的描述、版本、版本日期和发布者属性。可以添加用于电子访问图书馆的位置。

 

在broder意义上，IfcLibraryInformation包括用于在将库和其他数据检入修订控制系统时捕获修订信息的元数据。

 

IFC2x中的新实体。

IFC4：增加位置和描述属性；发布者和版本日期数据类型已更改；添加了HasLibraryReferences反向属性（以前的LibraryReference更改为反向）。
