Viewing and managing datasets in different spaces requires different space permissions.

## Permissions for viewing and managing datasets

You can view and manage datasets in your personal space. To interact with datasets in shared and managed spaces, you require specific permissions in those spaces.

信息注释This section only lists permissions for actions that are possible via the user interface. It does not list permissions for actions that are possible via API only.

### Viewing datasets and metadata

Space permissions are required in a space to view datasets and dataset metadata. Your permissions in the space must allow you to 列出并使用空间中的数据源. In shared spaces, the following user roles allow you to view datasets and metadata:

* 所有者

* 可管理

* 可编辑

* 可编辑应用程序中的数据

* 可使用数据

In managed spaces, the following user roles allow you to view datasets and metadata:

In shared spaces, the following user roles allow you to apply classifications and tags to datasets:

* 所有者

* 可管理

* 可编辑

* 可编辑应用程序中的数据

In managed spaces, the following user roles allow you to apply classifications and tags to datasets:
