Make this use the information from the running dagster instance.

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

Pull Request Overview
This PR adds comprehensive OpenMetadata integration to the data_platform code location, enabling metadata ingestion, lineage tracking, and data profiling from 8 major data sources (Trino, dbt, Dagster, Redash, Superset, S3, Iceberg, Airbyte). The implementation includes 12 ingestion assets, 2 schedules for regular updates, and supporting infrastructure including an OpenMetadata client resource with Vault integration.
Key changes:
- Added OpenMetadata Python SDK dependency (~1.7.0)
- Created 12 metadata ingestion assets covering metadata, lineage, and profiling
- Implemented OpenMetadata client resource with environment-specific configuration
- Added scheduled jobs for daily and critical source updates
- Comprehensive documentation for usage and deployment

The dev environment URL uses 'open-metadata-ci' instead of 'open-metadata-dev'. Verify this is the correct URL for the development environment, as the naming is inconsistent with the standard dev/qa/production pattern.

There was a problem hiding this comment.
Bug: In run_metadata_workflow, if MetadataWorkflow.create() fails, workflow.stop() in the finally block raises an UnboundLocalError because workflow is never assigned, masking the original error.
Severity: HIGH
Suggested Fix
Initialize workflow = None before the try block. In the finally block, check if the workflow variable was successfully assigned before calling .stop() on it, for example: if workflow: workflow.stop().

Location: dg_projects/data_platform/data_platform/assets/metadata/ingestion.py#L95
Potential issue: In the `run_metadata_workflow` function, the `workflow` variable is
assigned within a `try` block. If `MetadataWorkflow.create()` fails (e.g., due to
invalid configuration), the variable is never assigned. The `finally` block
unconditionally calls `workflow.stop()`, which will raise an `UnboundLocalError`. This
new error masks the original, more informative exception, complicating debugging
efforts.

There was a problem hiding this comment.
Bug: If vault authentication succeeds but resource creation fails, assets are still loaded. Executing these assets will cause a runtime AttributeError when they access the missing resources.
Severity: HIGH
Suggested Fix
Ensure that if resource creation fails, the corresponding assets that depend on them are not loaded. This could be done by setting vault_authenticated to False within the except block where resource creation failures are caught, or by using a more granular flag for each resource.

Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not
valid.
Location: dg_projects/data_platform/data_platform/definitions.py#L203
Potential issue: If Vault authentication succeeds (`vault_authenticated` is `True`), but
the subsequent creation of a required resource like `superset_api` or
`airbyte_workspace` fails, the failure is only logged as a warning. However, the
associated metadata assets are still loaded into the Dagster definitions. When these
assets are executed, they will attempt to access the missing resources from the context,
causing a runtime `AttributeError`.

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.
