We do have a functioning Superset API integration that is used in the lakehouse code location.

Overview
This PR implements comprehensive OpenMetadata integration for the MIT Open Learning data platform, enabling automated metadata ingestion, lineage tracking, and data profiling from all platform components. This addresses the need for improved data discovery and data governance capabilities.
Implementation Details
Assets Created (12 total)
The implementation provides Dagster assets that execute OpenMetadata workflows for metadata ingestion:
Metadata Ingestion (8 assets)
openmetadata__trino__metadata- Ingests table schemas, columns, and database structure from Trino/Starburst Galaxyopenmetadata__dbt__metadata- Ingests dbt model definitions, documentation, and tests from dbt artifactsopenmetadata__dagster__metadata- Ingests Dagster pipeline definitions and assetsopenmetadata__superset__metadata- Ingests Superset dashboards, charts, and dataset definitionsopenmetadata__airbyte__metadata- Ingests Airbyte connection and sync informationopenmetadata__s3__metadata- Ingests S3 bucket and object structureopenmetadata__iceberg__metadata- Ingests Apache Iceberg table metadata, schemas, and partitioningopenmetadata__redash__metadata- Ingests Redash query and dashboard definitionsLineage Tracking (2 assets)
openmetadata__trino__lineage- Analyzes Trino query logs to extract data lineage (7-day window)openmetadata__dbt__lineage- Extracts dbt model dependencies and lineage relationshipsData Profiling (2 assets)
openmetadata__trino__profiling- Runs statistical profiling on Trino tables for data quality metricsopenmetadata__iceberg__profiling- Runs statistical profiling on Iceberg tablesSchedules
Two schedules provide automated metadata updates:
Both schedules default to STOPPED status and should be enabled in production after configuration.
