Reverse Metadata Application

The Reverse Metadata Application enables seamless synchronization of metadata updates made in Collate back to the original data sources.
This ensures that Collate remains the single source of truth for metadata while maintaining consistency across platforms and reinforcing governance policies.

Overview

With this application, you can automatically propagate metadata changes such as:

  • Descriptions
  • Owners
  • Tags (e.g., PII-sensitive classifications)

These updates are pushed directly to supported data source systems, including Snowflake, enabling real-time enforcement of data governance controls such as masking policies.

Key Features

  • Automated Metadata Propagation:
    Sync metadata updates (tags, owners, descriptions) from Collate to source systems without manual intervention.

  • Configurable Channels:
    Define multiple sync channels to target different services, asset types, or metadata types.

  • Custom SQL Templates:
    Use SQL templates to customize update behavior per connector.

  • On-Demand or Scheduled Execution:
    Run synchronization workflows manually or on a predefined schedule.
