The Metadata details page lets you view the complete metadata for assets in DataWorks Data Map (tables, AI assets, multi-modal datasets, workspaces, projects, and so on), including basic information, columns, lineage, usage, data preview, data health, and notes. This topic introduces the overall layout of the metadata details page and the entries to the sub-topics.
Open the metadata details page
You can open the metadata details page of an asset from any of the following entries:
-
Click an asset name in the result list of Search for data assets in Data Map.
-
In the left tree of the Data Catalog, click a table, dataset, or other asset node.
-
In the My Data or My Favorites list, click the asset name.
-
In a data album details page, click the name of an asset that belongs to the album.
Page layout
The metadata details page renders different content depending on the asset type. Common areas include:
-
Header: Shows the asset name, type tag, description, and the operation button group in the upper-right corner (such as Apply for permission, Add to album, Favorite, Generate API, Data analysis, AI enhancement, Refresh metadata). Available buttons depend on the asset type, tenant activation, and your permissions.
-
Left basic information panel: Collapsible, showing core fields for the asset (such as owner, project, lifecycle, last update time). If the administrator has configured custom attributes for this asset type, a Custom Attributes card appears at the bottom of the panel.
-
Right tab area: Dynamically displays tabs based on the asset type. Table assets may include: Column details, Output information, Lineage, Data health, Usage records, Data preview, Data exploration, Data insights, Notes, and Related information. Whether each tab is visible depends on the data source type, tenant activation, and permissions.
