# External Repositories {#external-repositories}

If you wish to display records from a repository which is not part of your project, or is in a dependency which does not natively support Anthology, you can do so by creating a custom model and repository which extend the original.

The following examples assume you wish to display records created by [`friendsoftypo3/tt-address`](https://packagist.org/packages/friendsoftypo3/tt-address), but the same principles apply to any repository.

## Model {#model}

Create a new model which extends the original. Unless required, you don't need to add any additional properties or methods to this model.

**Classes/Domain/Model/Address.php**

```php
<?php

declare(strict_types=1);

namespace Vendor\MyExtension\Domain\Model;

use FriendsOfTYPO3\TtAddress\Domain\Model\Address as AddressOriginal;

class Address extends AddressOriginal
{
}
```

## Repostory {#repostory}

As a pair to the model created above, you also need to create a repository which extends the original, and add the `AsAnthologyRepository` attribute:

**Classes/Domain/Repository/AddressRepository.php**

```php
<?php

declare(strict_types=1);

namespace Vendor\MyExtension\Domain\Repository;

use FriendsOfTYPO3\TtAddress\Domain\Repository\AddressRepository as AddressRepositoryOriginal;
use LiquidLight\Anthology\Attribute\AsAnthologyRepository;

#[AsAnthologyRepository('tt_address')]
class AddressRepository extends AddressRepositoryOriginal
{
}
```

## Configuration {#configuration}

Finally, you must configure TYPO3 to use your newly created model and repository with the original table.

**Configuration/Extbase/Persistence/Classes.php**

```php
<?php

use Vendor\MyExtension\Domain\Model\Address;

return [
	Address::class => [
		'tableName' => 'tt_address',
	],
];
```

After completing the steps above and clearing the cache, your new model will be available for selection in the Anthology plugin.
