Description

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. Watson Knowledge Catalog provides fine-grain control of which users can perform which tasks through a combination of user roles and permissions and collaborator roles that control what actions users can perform.

The data governance framework is composed of governance artifacts that enrich data assets and data protection rules that define how to protect sensitive data from unauthorized access. Governance artifacts are organized in categories and subject to workflow. Data Stewards and Data Quality Analysts who are collaborators in categories and have the required roles can create governance artifacts, import artifacts from files, or import artifacts from IBM Knowledge Accelerators.

If you have the Data Governance Express® offering, the features of the Watson Knowledge Catalog service that are included in the following optional installation components are not available:

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.
  • 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.

The default catalog is created automatically after you install the Watson Knowledge Catalog service.

Data Stewards and Data Quality Analysts can import asset metadata to a project to enrich the assets through profiling, quality analysis, and assigning business terms. Data Scientists and Business Analysts can copy catalog assets into projects to analyze data and build models. They can also publish data and analytical assets to any catalog. Watson Knowledge Catalog includes these tools in projects:

  • The Data Refinery tool for preparing and visualizing data.
  • The Metadata import tool to import asset metadata into a project or a catalog.
  • The Metadata enrichment tool to profile data, analyze the data quality, automatically assign governance artifacts to the data assets, and then publish the data assets with the enrichment results to a catalog of choice.
  • Data quality rules to evaluate the quality of data.
