# tags - Composite topics

> Organizes composite topics by category.

Organizes composite topics by category, enabling you to group and filter composite topics by category and make it easier to organize your semantic model. They can be used to organize composite topics by domain, audience, data sensitivity, or any other categorization scheme that fits your organization's needs.

Tags can be referenced in the model's [`ai_chat_topics`](/modeling/models/ai-chat-topics) parameter with the syntax `tag:tag_name` to control which composite topics the Omni Agent can use.

## Syntax

```yaml theme={null}
tags: [<tag>, ...]
```

## Properties

<ParamField path="tags" type="string[]">
  A comma-delimited list of strings used to organize and group composite topics.
</ParamField>

## Examples

```yaml title="Categorizing by audience and domain" theme={null}
topics: [orders, marketing]
tags: [customer_facing, revenue]
```

```yaml title="Multiple categorization dimensions" theme={null}
topics: [employees, payroll]
tags: [internal, hr, sensitive]
```

```yaml title="Single tag" theme={null}

### Make tagged composite topics available to the Omni Agent
