Governance refers to Data Governance in MDM.
...
Operation ACLs are not part of zone data governance but should be mentioned briefly here. By default, the DGS has permission to modify ACLs to data records (DRs) to zone users and adaptors to create new DRs. Operational ACLs control operations to the underlying DRs are granted by the DGS to Zone Users and Adaptors; typically the ZDSs.

- At the highest prioirty level (Priority 1), Zone[1] can shut off all outbound data record changes to Zone[2]. At the lowest priority level (Prioirty 5), Zone[1] can shut off sharing a single attribute on a single adaptor (that it owns) to Zone[2].
- Sharing precedence is based on the priority e.g. If Zone[1] has turned off access to Zone[2] (Priority 1), then all other sharing actions are null.
- Permissions for each element are based on REST operations GET, PATCH, POST and DELETE. An additional operation is added for PUSH, where a zone allows another zone to receive real-time changes. However, it may be determined that GET will include PUSH.

Complete ACL Data Flow Illustration
The image below represents an example of MDM domain-related permissions and operational, outbound, and inbound ACLs (traveling left to right). Additional text below the image describes the process in addition to the embedded in-image text.
...
- On the diagram's left side is a source zone’s single Source Adaptor (abcd-1234) that sends data changes (data records) in its domain(s) to the router.
- Note: A zone can have many adaptors.
- The data records sent from the source adaptor to the router have Operational ACL applied to them. Operational ACL limits which data operations are allowed from the source zone’s adaptor(s) and adaptor domain(s) and are defined by the zone's DGS.
- Next, the data records from the source zone’s domains/adaptors are linked to YOUnite Data Records to avoid data record duplication.
- Note: The data records published by the source adaptor could be updates, deletes, or new records.
- Outbound ACLs then get applied to the source adaptor’s data records. The Outbound ACLs are defined by the source zone’s ZDS and define what data the Zone can send out (i.e .restricting data, or elements of data, of certain domains from flowing out of certain adaptors in the zone to other zones).
- After Outbound ACLs are applied the data records are published to the YOUnite Data Hub and subscribing/desitnation zones and their adaptors (on the diagram's right side) are notified of the updated data.
- Any destination zone that has subscribed to data records from the source zone has Inbound ACLs in place to define which data operations are allowed in the source zone and its adaptor(s). Inbound ACL is defined by the destination zone’s ZDS. Any data or operations that are configured to be ignored are filtered out. The Destination Adaptor (zyxw-9876) in the image above is shown receiving data records and/or operations it has subscribed to, as filtered by its zone’s Inbound ACL.
