An audit log is an example of what?

An audit log is indeed an example of metadata because it contains data that describes other data. Specifically, an audit log provides a record of activities, transactions, and changes that have occurred within a system, detailing aspects such as who accessed the data, when it was accessed, and what actions were taken. This information is essential for tracking and monitoring the usage of data, making it a crucial component of information governance and compliance.

Metadata serves as contextual information for data, allowing users to understand the origins of the data, its format, and any modifications made over time. In the case of audit logs, they enhance the ability to manage and safeguard information, ensuring transparency and accountability.

Understanding metadata's role helps professionals in health information management maintain more reliable and accurate health records, which is vital for compliance and quality assurance. The other options relate to different aspects of data protection and management but do not encapsulate the defining characteristics of audit logs.
