Finding and viewing an asset in a catalog
You find assets in a catalog on the Browse page.
Browse for an asset
Before you search, you can browse through these types of assets:
- Recently added assets
- Recommended assets
- Highly rated assets
Click Watson Recommends to see up to 20 assets that are recommended for you. Watson Knowledge Catalog uses Watson Machine Learning to derive a list of assets that you haven’t accessed yet based on attributes common to the assets that you’ve viewed, created, and added to projects, such as tags, asset classification, data classes, data types, asset owners, and asset types.
The more assets you access, the better the recommendations are.
Search for an asset
To search for an asset, enter keywords in the search field for matches in these asset properties:
- Business terms that are associated with assets
- Column names
You can filter results by tags, business terms that are associated with data assets, and asset types.
You can sort results by name, asset type, business terms, and date added.
View an asset
To view an asset in a catalog, click its name. You’ll see a set of pages about the asset:
The asset Overview page shows the asset properties, such as the description, tags, format, size, and date added. If you have permission, you can edit asset properties on this page.
If the asset has an associated file that is stored in the catalog’s storage, you can download the file.
You’ll see a preview of the contents of the asset if the asset type supports previews and you have the proper permissions. Whether you have permission to see the preview of an asset depends on whether you are a member of the asset, the privacy settings of the asset, and policies:
- Owner: You can always see the preview, regardless of policies.
- Member: You can see the preview unless you are blocked by policies.
- Not a member: You can see the preview if the privacy setting is public and you are not blocked by a policy.
If you see a shield icon next to the column name of a relational data asset, it means that the data in the column is masked by a policy. The owner of the asset is not affected by policies and always sees the original values.
The Access page shows the asset owner, the privacy setting, and the asset members. If you have permission, you can control access to an asset on this page.
For data assets, the Profile page shows profile information about the contents of the asset.
The Review page shows the ratings and reviews of the asset by catalog collaborators. You can rate the asset and write a review on this page.
The Lineage page shows the lineage graph for the asset. Lineage is the history of the events performed on the asset.
