class OpenLineageIntegration(GraiIntegrationImplementation)

A class for extracting Grai compliant metadata from an OpenLineage json string.

Attributes:

• lineage_data - A dictionary parsing of a OpenLineage json file
• namespace - The Grai namespace to associate with output from the integration
• namespaces - A dictionary of namespace aliases to use when parsing the lineage data

__init__

def __init__(lineage_data: Union[str, dict],
             source: SourceV1,
             version: Optional[str] = None,
             namespace: Optional[str] = "default",
             namespaces: Optional[Dict[str, str]] = None)

Initializes the dbt integration.

Arguments:

• lineage_data - Either a string path to a manifest.json file, or a dictionary parsing of a manifest.json file
• source - The Grai data source to associate with output from the integration. More information about source objects is available in the grai_schemas library.
• version - The Grai data version to associate with output from the integration
• namespace - The Grai namespace to associate with output from the integration
• namespaces - A dictionary of namespace aliases to use when parsing the lineage data
