class MyTranslator(DagsterEvidenceTranslator):
    def get_asset_spec(self, data):
        if isinstance(data, EvidenceSourceTranslatorData):
            # Custom logic for source assets
            return dg.AssetSpec(
                key=dg.AssetKey(["custom", data.query.name]),
                kinds={"evidence", data.source_content.connection.type},
            )
        return super().get_asset_spec(data)
