Advantages of a Graph-Based Metadata Repository [Community Post]

The University of Washington (UW) is implementing a large Software-as-a-Service solution for HR and payroll, replacing its 30+ year-old system. To facilitate this change, the university created Knowledge Navigator (KN), a metadata repository that provides a web-based, interactive platform to understand data relationships and changes between old and new systems. KN offers self-service access to conceptual and technical descriptions, definitions, lineage, and impact analysis information, enabling users to stay informed and engaged throughout the system migration. The solution is designed to provide a common understanding and expectations across the university, managing metadata to oversee changes while delivering trusted, secure data in complex environments. By focusing on a specific problem and using a simple data model, KN stands out among metadata repositories with its unique ability to communicate about changes to end-users, illustrating parallels between old and new systems through interactive diagrams and explaining new concepts and definitions.
