如前所述，这些数据是关于应用程序的元数据词典。
As I mentioned, the data is a dictionary of metadata about the application.
例如，“数据词典”和“数据模型”与元数据相关；而词汇表、控制词汇和分类法则与数据实例相关。
For example, "data dictionary" and "data model" are related to the metadata; whereas glossary, controlled vocabulary and taxonomy concern the data instances.
