# gable data-asset create-contract

Creates the YAML contract specification for a list of data assets. If a regex
pattern (`--data-asset-id-pattern`) is provided, the command will create contracts
for all data assets that match the pattern as well as the data assets provided in.

The specification that is produced is based off the registered data asset but the
user will need to fill in places marked with 'PLACEHOLDER:' such as field
descriptions and ownership information.

## Usage

```bash theme={null}
gable data-asset create-contract [DATA_ASSET_IDS] [OPTIONS]
