原始的存储库和其副本均包含同样的数据地图对象，这是因为数据地图是不能修改的，这一点在本文稍后的部分介绍。

Both the original repository and its copy will contain the same data map objects , which is correct because data maps cannot be modified , as you 'll see later in this article .

这些副本都包含与原始存储库相同的数据地图对象，这一点没错，因为数据地图在用表单数据创建和填充之后不会被修改。

These copies , however , contain the same data map objects as the original repository , which is OK because data maps are not modified after being created and populated with the form data .
