# Attributes

The `Attributes` table acts as an intermediate table to connect the `Layers` table and the `Tokens` table. Each row consists of a token id and a layer id. This allows token data and layer data to be joined on each other which ultimately yields the necessary NFT metadata.

## Storage

### Tableland

The `Attributes` table in Tableland has the following schema:

```json
{
    "token_id": integer (FK)
    "layer_id": integer (FK)
}
```

* `token_id`: Integer representing an `id` in the `Tokens` table
* `layer_id`: Integer representing an `id` in the `Layers` table
