Catalog assets

An asset in a catalog contains information about data or data analysis. There’s no limit to the number of assets in a catalog.

The information about assets that is stored in a catalog includes:

If policies are enforced for the catalog, they can block specific catalog members from viewing or using the asset. You can also decide to mask data in asset columns depending on their contents. In this case users can view an asset but not all data is revealed to them. A shield icon a shield icon next to the column name indicates that the data in the column is masked by a policy.

Types of assets

You can add assets from these types of sources to a catalog:

  • Files from your local system, including structured data, unstructured data, and images
  • Connections to data sources. You can add connections to IBM or third-party data sources.
  • Data assets from a connection to a data source
  • Folder assets) from a connection to a file system
  • Data assets from projects
  • Notebooks from projects
  • Trained Watson Machine Learning models from projects
  • Dashboards from projects
  • Database, schema, table, and connection assets from IBM InfoSphere Information Governance Catalog

Note: Files that are associated with assets, such as local files or notebooks, are stored in the IBM Cloud Object Storage bucket that is associated with the catalog.

Asset properties

All asset types have a common set of properties. Some asset types have additional properties.

When you add an asset to a catalog or edit an existing asset, you specify these common properties:

  • The asset name and an optional description. The asset name cannot be empty, contain Unicode control characters, or contain only blank spaces. You can include links in the description.
  • Asset format. Automatically detected.
  • Tags. Ungoverned metadata that makes searching for the asset easier. Tags can contain only spaces, letters, numbers, underscores, dashes, and the symbols # and @. Click the plus sign icon to add tags.
  • If the catalog has policies enforced, a classification for the data asset.
  • Data classes that are assigned to the asset and to columns in data assets.

Asset access

You can control access to an asset on the Access page with the privacy level and asset membership:

  • Privacy. You can choose whether to restrict access to the asset:
    • Public = Default. No restrictions on finding or using the asset.
    • Private = Only asset members can find or use the asset.
  • Members. The catalog collaborators to add as members of the asset. Members are important if you restrict access to the asset.
