Amazon SageMaker Unified Studio is in preview release and is subject to change.
Manage inventory and curate assets in Amazon SageMaker Unified Studio
In order to use Amazon SageMaker Unified Studio to catalog your data, you must first bring your data (assets) as inventory of your project in Amazon SageMaker Unified Studio. Creating inventory for a particular project makes the assets discoverable only to that project’s members.
After the assets are created in project inventory, their metadata can be curated. For example, you can edit the asset's name, description, or README. Each edit to the asset creates a new version of the asset. You can use the History tab on the asset's details page to view all asset versions.
You can edit the README section and add rich descriptions for the asset. The README section supports markdown, thus enabling you to format your descriptions as required and describe key information about an asset to consumers.
Glossary terms can be added at the asset level by filling out available forms.
To curate the schema, you can review the columns, add business names, descriptions, and add glossary terms at column level.
If automated metadata generation is enabled when the data source is created, the business names for assets and columns are available to review and accept or reject individually or all at once.
You can also edit the subscription terms to specify if approval for the asset is required or not.
Metadata forms in Amazon SageMaker Unified Studio enable you to extend a data asset's metadata model by adding custom-defined attributes (for example, sales region, sales year, and sales quarter). The metadata forms that are attached to an asset type are applied to all assets created from that asset type. You can also add additional metadata forms to individual assets as part of the data source run or after it's created. For creating new forms, see Create a metadata form in Amazon SageMaker Unified Studio.
To update the metadata of an asset, you must be the owner or the contributor of the project to which the asset belongs.
To update the metadata of an asset
-
Navigate to Amazon SageMaker Unified Studio using the URL from your admin and log in using your SSO or AWS credentials.
-
Choose Select project from the top navigation pane and select the project to which the asset belongs.
-
Under Project catalog in the left side navigation, choose Assets.
-
Make sure you are on the Inventory tab, then choose the name of the asset that you want to publish. You are then brought to the asset details page.
-
On the asset details page, under Metadata forms, choose Edit values to edit the existing forms as needed, or choose Add metadata form and enter values for each of the metadata fields to attach additional metadata forms to the asset.
-
When you're done making updates, choose Save.
When you save the form, Amazon SageMaker Unified Studio generates a new inventory version of the asset. To publish the updated version to the catalog, choose Re-publish asset.
By default, metadata forms attached to a domain are attached to all assets published to that domain. Data publishers can associate additional metadata forms to individual assets in order to provide additional context.
When you are satisfied with the asset curation, the data owner can publish an asset version to the Amazon SageMaker Unified Studio catalog and thus make it discoverable by all domain users. The asset in the project shows the inventory version and the published version. In the discovery catalog, only the latest published version appears. If the metadata is updated after publishing, then a new inventory version will be available for publishing to the catalog.
