Finding

OpenMetadata includes an IOMETE database connector, but docs-om does not have a v1.13 connector page for it.

Evidence

• Product code: ingestion/src/metadata/ingestion/source/database/iomete/service_spec.py and sibling source files exist in OpenMetadata.
• Setup registration: ingestion/setup.py includes the iomete extra.
• Docs check: no v1.13.x-SNAPSHOT/connectors/database/iomete page exists in docs-om.

Acceptance criteria

• Add the IOMETE connector overview page under v1.13.x-SNAPSHOT/connectors/database/iomete/.
• Add YAML/UI ingestion guidance and required connection settings.
• Add the connector to v1.13 navigation and connector listings.
• Run mint broken-links successfully.
