Schema Management

Schemas are the primary records in the CDM Registry. Each schema represents a registered data model that can be discovered and reused across the organization.

Schemas contain metadata such as descriptions, source systems, tags, interfaces, and dependencies. A Registry schema can optionally be linked to a Negroni manifest, but the schema record itself can exist without a manifest link.

For browsing registered schemas, see Entity Catalog. For managing interfaces and dependencies, see Interface Management and Dependency Tracking.

Registering a Registry Schema

To register a new schema:

  1. Click the Add Schema button.
  2. Enter the required schema information.
  3. Click Save.

The schema becomes available in the Entity Catalog after registration.

Editing a Schema

To update a schema:

  1. Open the schema from the Entity Catalog.
  2. Update schema details using the right-side Properties panel.
  3. Click Save Save.

Changes are applied immediately to the Registry.

Deleting a Schema

To remove a schema:

  1. Open the schema from the Entity Catalog.
  2. Click Delete.
  3. Confirm deletion.

Deleting a schema removes it from the Registry and makes it unavailable for discovery.

Dependency impact

Before deleting a schema, review its dependencies to avoid affecting related schemas.

Searching and Filtering Schemas

Use available filters to quickly find schemas:

  • Search bar — search by schema name
  • Source System filter — filter by source system
  • Tag filters — filter using assigned tags

Filtering helps organize and locate schemas more efficiently.

Viewing Schema Details

Select a schema from the Entity Catalog to open its detailed view.

The schema detail view includes:

  • Metadata
  • Description
  • Source system
  • Tags
  • Interfaces
  • Dependencies
  • Last modified information

Use schema details to understand how a data model is structured and connected to other schemas.
