## Data Contract Validation
The library can be used to validate your .yaml data contract against Open Data Contract Standard JSON schema from [Bitol-io / open-data-contract-standard](https://github.com/bitol-io/open-data-contract-standard/)
### Installation
```
pip install -U datamesh
```
### Usage
```bash
data-contract-validation <path_to_contract_yaml_file> <optional_path_to_standards_json_schema>
```
or in Python
```python
from datamesh.contract import Validator
validation_errors = (
Validator(
contract="examples/all/postgresql-adventureworks-contract.yaml",
standard="schema/odcs-json-schema.json"
)
.print_report()
.errors
)
```
```
🚩 Validation errors:
.
│
├──[]
│ └── 'datasetName' is a required property
│
├──[]
│ └── 'quantumName' is a required property
│
├──['kind']
│ └── 'managedDataset' is not one of ['DataContract']
```
