Which type of metadata is used for discovery and identification of a file?

• A. Administrative metadata
• B. Structural metadata
• C. Descriptive metadata
• D. Data integrity metadata

Answer: (C)

Descriptive metadata is used for the discovery and identification of a file because it provides essential information that helps users find and understand the content of the file. This type of metadata typically includes details such as the title, author, keywords, and abstract, which facilitate searching and categorization. By offering contextual information, descriptive metadata enables users to ascertain the relevance of a file to their needs, ultimately aiding in efficient data retrieval and organization.

In contrast, administrative metadata pertains to the management of the file itself, such as its creation date, access permissions, and file type. Structural metadata describes the internal structure of a file, like how different components are organized or the relationships between items within the dataset. Data integrity metadata focuses on preserving the accuracy and consistency of the data over time, monitoring its quality and integrity. While each of these types of metadata serves its own purpose, they do not primarily function to help users discover and identify files in the way that descriptive metadata does.
