Which component must be enabled in order to render business lineage when installing IBM Knowledge Catalog?

Business lineage in IBM Knowledge Catalog provides a graphical representation of the relationships between various assets, such as business terms, data assets, reports, and governance artifacts. This complex network of relationships and the flow of data are stored, managed, and rendered using the underlying knowledge graph technology. The knowledge graph serves as the foundational repository for the metadata and relationships that are visualized in the business lineage report. Therefore, this component must be enabled during installation to support the business lineage feature.

A. Automated metadata lineage: This feature imports detailed technical lineage from external sources into the catalog; it populates the knowledge graph but is not the core rendering component itself.
C. Data graph: This is a generic industry term. The specific IBM component that manages and renders these relationships within IBM Knowledge Catalog is officially termed the "knowledge graph".
D. Data quality: This component is used for assessing, monitoring, and improving the quality of data assets, a function distinct from visualizing the flow and lineage of data.

1. IBM Cloud Pak for Data 4.8 Documentation, "Lineage": "Lineage information is stored in the knowledge graph along with other metadata about assets... Business lineage shows a simplified, high-level view of lineage information that is most interesting to business users." This statement directly links the knowledge graph to the storage and presentation of business lineage.

2. IBM Cloud Pak for Data 4.8 Documentation, "Installing Watson Knowledge Catalog": The installation guide specifies the services that constitute the Watson Knowledge Catalog. The advanced features, including governance and lineage, rely on the core services which include the underlying graph database technology that powers the knowledge graph. The "wkc-gov-ui" service, responsible for the governance UI including lineage, depends on these core data services.

3. IBM Cloud Pak for Data 4.8 Documentation, "Managing business lineage": This section details how to work with business lineage reports. The entire functionality described—visualizing asset flows, adding details, and exporting—is powered by the data stored and organized within the knowledge graph.
