# Namespaces

> Isolated message scopes within your Noetive account.

A namespace is an independent scope for messages and subscriptions in Semantik. Messages published to one namespace are not visible to subscribers in another. Each namespace has its own real-time metrics.

## Creating a namespace

1. Go to the [Semantik dashboard](https://noetive.io/dashboard/semantik).
2. In the namespace table, select **New namespace**.
3. Enter a name and save.

The table shows the new namespace alongside its auto-assigned **namespace ID**. Namespace IDs are assigned at creation and never change — you use this ID to scope SemQL queries.

<Info>
  Namespace creation requires an active subscription. If you land on a subscription-required page, complete billing setup under [Settings → Billing](https://noetive.io/settings/billing) first.
</Info>

## Using a namespace ID

Reference a namespace in SemQL via the `PARTITION` clause:

```sql theme={null}
MATCH DISTANCE("payment failure") WITHIN 0.3
PARTITION "your-namespace-id"
LIMIT 20
```

You can target multiple namespaces or combine with `GLOBAL`:

```sql theme={null}
MATCH DIRECTION(["outage", "service degradation"]) CONE 0.4
PARTITION "ns-prod", "ns-staging", GLOBAL
```

See [SemQL query language](/semantik/query-language) for the full partition selector syntax.

## Editing a namespace

Select **Edit** next to a namespace in the table to update its name. The namespace ID never changes.

## Deleting a namespace

<Warning>
  Deleting a namespace is irreversible. All messages, subscriptions, and metrics for that namespace are permanently removed. Active subscriptions in the namespace are terminated immediately.
</Warning>

Select **Delete** next to a namespace in the table and confirm the action.
