# Review and deploy a semantic model

> Review, approve/reject, and deploy a semantic model to make it available as a materialized view.

After a user has created a semantic model, you, as an administrator, can review, approve/reject,
and deploy it. Only after deploying the semantic model is a materialized view created.

## Prerequisites

* Appropriate permission: `nx1_semantic_admin`
* An existing semantic model having a `draft` status

## Review and deploy a semantic model

<Tabs>

    Perform these steps to review and deploy a semantic model.

    1. Log in to NexusOne.

    2. On the top navigation bar, hover your mouse over **Catalog & Models** and then select **Semantic Models**.

    3. Scroll through the table and click the three dots, `...`, at the right on your selected semantic model.

    4. Click **Submit for Review**.

    5. At the top of the table, click **Pending Reviews**.

    6. Scroll through the table and click **Review** on your selected semantic model.

    7. To approve or reject the semantic model, do one of the following:

       * Enter a review note stating the reason for rejecting the semantic model and click **Reject**.
       * Click **Approve** to approve the semantic model.

    8. Click **All Models**.

    9. Scroll through the table and click your selected semantic model.

    10. Click **Deploy**, then do one or more of the following:

        * Toggle the **Register in DataHub** button to register the deployed view for discovery.
        * Toggle the **Add Lineage** button to track data lineage from source tables in DataHub.
        * Toggle the **Create Dashboard** button to create a Superset dashboard.
        * Toggle the **Schedule Refresh** button and then enter a cron schedule to create
          an Airflow DAG for periodic refresh.

    11. Click **Deploy**.

    After deploying the semantic model, NexusOne creates a materialized view. Depending on your preferred
    selection in step 10, visit DataHub to see the data lineage of the materialized view, or Superset to
    view the materialized view's dashboard.

    Use the following API endpoints to:

    * [Get pending reviews](/api-reference/endpoints/semantic-models/get-pending-reviews)
    * [Approve model](/api-reference/endpoints/semantic-models/approve-model)
    * [Batch approve model](/api-reference/endpoints/semantic-models/batch-approve-models)
    * [Batch reject model](/api-reference/endpoints/semantic-models/batch-reject-models)
    * [Reject model](/api-reference/endpoints/semantic-models/reject-model)

    Because you are selecting an existing domain and semantic model you can use
    the following API endpoints to:

    * [Get domains](/api-reference/endpoints/metastore/get-domains)
    * [Get semantic model](/api-reference/endpoints/semantic-models/get-semantic-model)
  </Tab>
