Profiling data assets (Watson Knowledge Catalog)

The profile of a data asset includes generated metadata and statistics about its content. An asset profile helps you understand what actions to take to improve the data quality. You can see the profile on the asset’s Profile page in a catalog or in an analytics project. All catalog or project members can see data asset profiles.

In governed catalogs, automatic profiling for data assets is enabled by default. You must manually create profiles for structured data assets in governed catalogs if you disabled automatic profiling, in ungoverned catalogs, and in projects. Profile updates must also be triggered manually. Unstructured data assets cannot be profiled.

You must have the Admin or Editor role in the project or catalog to create or update a profile for a structured data asset.

To manually create a profile for a structured data asset:

  1. Go to the asset’s Profile page. If necessary, you are prompted to enter your personal credentials for the locked data connections.
  2. Optional. Click Select data classes, choose which data classes to include in the profile, and click Apply.
  3. Click Create profile.

You can update an existing profile for a structured data asset when the data changes or when you want to change the data classes to include in the profile.
