# dbt models with no owner

A Metacenta review checks this under the rule **Models declare an owner**. Everything below applies whether or not you ever commission one.

## What this rule checks

Where a project already owns models through dbt `groups:` or an owner-shaped `meta` key, this rule flags the models that carry neither. It measures the project against its own convention.

## Why it matters

A failure or a question about an unowned model has no named person to go to. It reaches whoever happens to remember, and the risk is a model that breaks without anyone noticing.

## How to fix it

**Bring the unowned models into the ownership convention already in use.** Put the model in a group, or set the same `meta` key the rest of the project uses. Assigning the whole folder in `dbt_project.yml` catches the next model too.

Before:

```yaml
models:
  jaffle_shop:
    marts:
      finance:
        +materialized: table
```

After:

```yaml
models:
  jaffle_shop:
    marts:
      finance:
        +materialized: table
        +group: finance
```

## When it is fine to leave

If ownership lives outside dbt, in a CODEOWNERS file or a rota, the models are owned in practice. With no convention in the manifest at all, the rule declines rather than flag every model.

## What we need to check it

`manifest.json`. The owner-shaped `meta` keys we recognise are `owner`, `owners`, `owner_email`, `owner_team`, `team`, `maintainer`, `maintainers`, `steward` and `contact`.
