Can the following IdentityIQ object be extended to store client-specific data by updating the corresponding...

Yes. CertificationItem is one of the IdentityIQ object areas that can be extended to store client-specific data through the supported extended-object/Hibernate mapping approach. The purpose of updating a corresponding .hbm file is to introduce persistent custom columns or mapped properties into the IdentityIQ database model. For certification use cases, client-specific data may need to be stored with review items, such as additional context, classification values, remediation metadata, or custom review attributes. The extension process must not stop at editing the mapping file. The Word bank’s schema-extension process describes the broader pattern: update the Hibernate mapping, generate the schema update script, apply the script to the IdentityIQ database while the application server is stopped, then start the application server and update the corresponding ObjectConfig. Therefore, CertificationItem is a valid object for this proposed extension approach, provided the engineer follows the full supported schema-extension process.
