Metadata within catalog is classified by:

• Content (business domain)
• Confidentiality (how secret asset is)
• Sensitivity (how personal asset is)
  • Nonpersonal data
  • PII
    • Personal data
    • Sensitive personal data

The most significant advantage of data governance supported by a data catalog is the ability to classify all data within the IT environment according to their sensitivity and confidentiality.

This capability can be of great value to both the Data Protection Officer (DPO) and the Chief Information Security Officer (CISO).

The data catalog applies rules to its data harvesting process, ensuring that all ingested resources are automatically assigned sensitivity and confidentiality classifications.
Additionally, by using the data lineage functionality, it is possible to track how data is used and transformed within the organization.
