Systems and techniques for metadata quality monitoring and remediation are described herein. Metadata is obtained from a system of record. The metadata is normalized. The metadata is evaluated with an integrity rule to identify a discrepancy in an element of the metadata. The discrepancy is stored as an integrity gap in an integrity database. A notification is generated that includes identification of the element of the metadata and a description of the integrity rule. The notification is transmitted to a user identified based on the integrity rule.
