# base_view

> Defines the base view for the topic.

<Warning>
  This parameter is required in topic files.
</Warning>

Defines the base view for the topic. Values should be unquoted. Quotes will be removed/ignored upon saving.

<Note>
  If a topic's `base_view` is ignored or excluded by model-level directives ([`ignored_views`](/modeling/models/ignored-views), [`ignored_schemas`](/modeling/models/ignored-schemas), [`included_views`](/modeling/models/included-views), [`included_schemas`](/modeling/models/included-schemas)) or by the view's [`ignored`](/modeling/views/parameters/ignored) parameter, it will be suppressed. This means that the topic will not appear in the topic picker and or be included in model validation.
</Note>

## Syntax

```yaml theme={null}
base_view: <view_name>

# Use <schema>__<view> to specify a schema
base_view: <schema>__<view_name>
```
