# Extension Metadata

The `extension.json` file contains all metadata necessary for the host application to understand and manage the extension:

``` json
{
  "name": "dataset_references",
  "version": "1.0.0",
  "frontend": {
    "contributions": {
      "views": {
        "sqllab.panels": [
          {
            "id": "dataset_references.main",
            "name": "Dataset references"
          }
        ]
      }
    },
    "moduleFederation": {
      "exposes": ["./index"]
    }
  },
  "backend": {
    "entryPoints": ["dataset_references.entrypoint"],
    "files": ["backend/src/dataset_references/**/*.py"]
  },
}
```

The `contributions` section declares how the extension extends Superset's functionality through views, commands, menus, and other contribution types. The `backend` section specifies entry points and files to include in the bundle.
