## Some Plutus Modules
|
||||
|
||||
- [`PlutusTx.Data`](https://github.com/input-output-hk/plutus/blob/master/plutus-tx/src/PlutusTx/Data.hs), contains the definition of the `Data` type.
|
||||
- [`PlutusTx.IsData.Class`](https://github.com/input-output-hk/plutus/blob/master/plutus-tx/src/PlutusTx/IsData/Class.hs), defines the `IsData` class.
