Governance refers specifically to data governance in MDM, and that governance is exercised via Access Control Lists (ACLs) for zones. ACLs control inbound and outbound messages to zones. As a reminder, a zone refers to a collection of systems/applications owned by groups inside of an organization and they act as a boundary for which access permissions may be defined. All resources within MDM belong to a zone. Each zone has a Zone Data Steward and a Zone Admin.

The Zone Data Steward (ZDS) is responsible for the data associated with a zone (through the adaptors) and can restrict outbound data shared with other zones and inbound data coming from other zones.
