Watson Knowledge Catalog on Cloud Pak for Data as a Service


Watson Knowledge Catalog is now one of the core services in Cloud Pak for Data as a Service.

Watson Knowledge Catalog provides a secure enterprise catalog management platform that is supported by a data governance framework. A catalog connects people to the data and knowledge that they need. The data governance framework ensures that data access and data quality are compliant with your business rules and standards.

A catalog is how you share assets across your enterprise:

  • Collaborators in a catalog have access to data assets without needing separate credentials or being able to see the credentials. Collaborators have roles that control what activities they can perform in the catalog.
  • An asset in a catalog consists of metadata about data, including how to access the data, the data format, the classification of the asset, which collaborators can access the data and other types of metadata that describe the data. Data assets can include both relational data and unstructured data, such as PDF or Microsoft Office documents.

You govern and curate data to provide high-quality data assets that are easy to find without exposing sensitive information to unauthorized users. You enrich, classify, and protect data sets with governance artifacts. Then, you publish the data sets as data assets to your catalogs where other users can find them.

You can copy catalog assets into projects to analyze data and build models. The Data Refinery tool for preparing and visualizing data is included with the Watson Knowledge Catalog service.
