This document discusses the concept of an "Inspector Graph", which is a knowledge graph that provides metadata and context about an organization's various data sources. It notes that data quality, visibility, and knowledge retention issues often arise due to the variety of applications and data models used across an organization. An Inspector Graph allows companies to view all of their data at a global level, retain information about data quality checks, and educate employees by maintaining business knowledge and data availability. The remainder of the document provides overviews and examples of how an Inspector Graph works using Neo4j to address these challenges.
