Which of the following is NOT an example of Metadata?

Metadata refers to the data that provides information about other data. It helps to describe various attributes of the data, such as its origin, purpose, and structure. Among the options provided, the storage structure of the data is directly related to how data is physically organized or stored within a database or system, rather than information about the content or context of the data itself.

The author or creator of the data, the purpose of the data, and the date and time of data creation all serve to give context and additional meaning to the data, which is precisely what metadata is intended to do. They help users understand the significance, intent, and historical context of the data, while the storage structure refers to the technical aspects of data management rather than its descriptive characteristics. Therefore, identifying the storage structure as not being an example of metadata accurately captures the distinction between content-related descriptors and technical specifications.
