# Data Asset Group (DAG)

DAG (Data Asset Group) provides a powerful mechanism for managing governance and security on data objects within OvalEdge. They allow administrators to:

* **Override Initial Governance:** Assign new Stewards, Custodians, and Owners to data objects, replacing those defined during data ingestion.
* **Set Security Permissions:** Control access to data objects by granting Metadata (view/edit) permissions to specific roles for DAG tags.
* **Create and Manage DAG Tags:** Define new tags and organize them hierarchically within the "Tags" section for easy management.

**Benefits of DAG:**

* **Centralized Governance:** Streamline governance assignments by managing stakeholders at the tag level.
* **Simplified Access Control:** Efficiently set permissions for groups of data objects using DAG tags.

**Creating and Managing DAGs (OE\_ADMIN only)**

OE\_ADMIN and users with the "ovaledge.role.admin" role can create and manage Data Asset Group (DAG) tags within OvalEdge.

**Actions**

* **Create DAGs:** Define new DAG tags to manage governance and security settings for data objects.
* **Manage Permissions:** Grant or revoke Metadata (view/edit) access to DAG tags for specific roles and users based on license limitations.
* **Set Security Inheritance:** Determine whether DAG security overrides the security defined directly on data objects (Authorized Roles and User Access permissions).
* **Delete DAGs:** Remove existing DAG tags. Upon deletion, associated data objects revert to their default access permissions and governance roles.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ovaledge.com/administration/security/data-asset-group-dag.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
