mcp-data-platform-v0.6.0

Semantic Enrichment Fixes

Fixes cross-injection between Trino and DataHub so table-level metadata (description, tags, domain, glossary terms, owners) flows correctly in both directions.

Bug Fixes

• Fixed table name extraction - trino_describe_table(catalog="x", schema="y", table="z") now correctly builds x.y.z for URN lookup (was only using z)
• Added reverse catalog mapping - DataHub URNs now correctly resolve to Trino table paths via query.urn_mapping.catalog_mapping
• Complete enrichment output - Added missing fields: urn, glossary_terms, custom_properties, last_modified
• Debug logging - Added slog.Debug when enrichment fails to help diagnose URN mismatches

Configuration

Bidirectional URN mapping is now supported:

semantic:
  provider: datahub
  instance: primary
  urn_mapping:
    platform: postgres
    catalog_mapping:
      rdbms: warehouse           # Trino → DataHub

query:
  provider: trino
  instance: production
  urn_mapping:
    catalog_mapping:
      warehouse: rdbms           # DataHub → Trino

Breaking Changes

None.

Upgrade Guide

Add urn_mapping configuration if your Trino catalogs differ from DataHub catalogs. Both semantic.urn_mapping and query.urn_mapping should be configured as reverse mappings of each other.
