Data Catalog

The Data Catalog is the central library of reusable database blueprints (Data Domains) on the API Now! platform.

Instead of re-creating standard database structures from scratch for every new project, you can browse, import, and share structured domain blueprints.

Why Publish to the Catalog?

To keep your backend architecture stable, the API Modeler cannot connect directly to a draft or actively changing Data Domain.

Before you can build endpoints or set up security rules, you must publish a versioned blueprint of your Data Domain to the Catalog.

• This acts as a “stable release” of your database structure.
• Once published, your API Model attaches to this specific version (e.g., 1.0.0).
• If you need to make changes to your database later, you design the updates as a new draft, publish a new version (e.g., 1.1.0), and upgrade your API when you are ready.

Publishing Scopes (Visibility Levels)

When you publish a Data Domain to the Catalog, you can choose who has access to view, import, or connect to that model:

Scope	Visibility	Ideal Use Case
Private	Only visible to you.	Drafting new blueprints, personal testing, or sandbox experimentation.
Organization	Visible to all members inside your API Now! organization space.	Standardizing schemas for team-wide projects (e.g., sharing a unified Customer structure).
Public	Globally visible to all builders on the API Now! platform.	Sharing open-source database templates or industry-standard schemas.

How to Publish a Domain

1. Open your draft inside the Domain Modeler.
2. Once your tables and smart fields are configured, click the Publish to Catalog button in the top navigation bar.
3. Set the Version Tag (following semantic guidelines, e.g., 1.0.0).
4. Select your desired Publishing Scope (Private, Organization, or Public).
5. Click Publish. Once completed, this version becomes immediately available in the API Modeler dropdown list.
