# shared_views

> Dimension tables joinable from every included topic, such as a date spine.

Defines dimension tables that are joinable from every included topic — typically a date spine, region table, or product catalog. Omni auto-detects shared views on file creation; edit the list as needed.

Dimensions from a shared view are selectable as join keys for any topic. Measures on a shared view are aggregated **per topic**, not combined.

## Syntax

```yaml theme={null}
shared_views: [<view_name>, <view_name>, ...]
```

## Properties

<ParamField path="shared_views" type="string[]">
  A list of view names joinable from every included topic — either as the base view of every topic or through the model's relationships. The validator surfaces an error if a listed view is not joinable from every topic.
</ParamField>

## Examples

```yaml theme={null}
shared_views: [date_spine, regions]
```

Because a shared view like `date_spine` is joined into every topic, every row in the spine appears in the result — for example, every day appears even when a topic has no activity that day.
