Improved Pack: Built-in Identifier Reference

Public preview

This feature is automatically enabled for all new tenants. If you are an existing customer, reach out to your Immuta support professional to use this feature.

Immuta comes with a pack of built-in identifiers that look for common data types. And since the first pack was released, improvements have been made. These improvements are now available in this improved pack, which includes some unchanged identifiers, but also many new and improved versions of legacy identifiers. These identifiers were written by Immuta's research and development team and cannot be deleted or edited by users. However, users can add these built-in identifiers to their own frameworks and edit the tags applied by them.
