Governance artifacts (Watson Knowledge Catalog)

Governance is the process of curating, enriching, and controlling your data. You govern your data with governance artifacts, and you organize and control access to governance artifacts with categories.

You can create these types of governance artifacts:

  • Classifications: You use classifications to describe the sensitivity of the data in data assets. Each data asset has one classification. Catalog collaborators assign the classification when they add data assets to a governed catalog. You can also assign classifications to governance artifacts, such as business terms, data classes, reference data, policies, and governance rules.

  • Data classes: You use data classes to categorize columns in relational data sets according to the type of the data and how the data is used. One data class is assigned to each column during profiling within a catalog. Catalog collaborators can change the data class assigned to a column. Users with the Manage asset discovery permission can assign data classes to data set columns before adding the data to a catalog.

  • Reference data sets: You create reference data sets to define values for specific types of columns. You can include a reference data set in the definition of a data class as part of the data matching criteria. During data profiling, if the values in a column match the reference data set and other criteria, that data class is assigned to the column. You can also use reference data sets in data quality analysis.

  • Business terms: You create business terms to define business concepts in a standard way for your enterprise. Catalog collaborators can assign one or more terms to data assets and columns within relational data sets to describe the data. Users with the Manage asset discovery permission can add business terms to data sets before adding them to a catalog.

  • Policies: You create policies to describe how to govern data in catalogs. You can include data protection rules in policies to control and manage data. You can also include governance rules in policies to describe data.

  • Rules: You can create the following types of rules:

    • Data protection rules: You create data protection rules to identify the data to control and to specify the method of control. Within data protection rules, you can include classifications, data classes, business terms, or tags to identify the data to control. You can choose to deny access to data or to mask sensitive data values.

    • Governance rules: You create governance rules to provide a natural-language description of the criteria that are used to determine whether data assets are compliant with business objectives.

You can import a Knowledge Accelerator specific to your industry to provide categories, business terms, and reference data sets.

This diagram shows an overview of how governance artifacts work together to describe, enrich, improve, and protect data. Governance artifacts can have more relationships than are shown in this diagram with other artifacts and data assets. This image shows how governance artifacts work together.

You organize both governance artifacts and the users who can view, create, and manage those artifacts in categories. You control which users can view or manage categories by adding users as collaborators to categories and assigning them roles that determine their permissions. Users must have sufficient user permissions on the platform and must be added as category collaborators.
