Which term refers to secondary data that organizes, manages, and facilitates the use and understanding of primary data in electronic discovery?

The correct choice is metadata, which refers to data that provides information about other data. In the context of electronic discovery, metadata plays a crucial role in organizing and managing primary data, such as documents and files. It contains details about the primary data, such as the file creation date, author, and modification history. This additional information helps investigators understand the context and relevance of the primary data, making it easier to facilitate its use during discovery processes.

Metadata serves various functions, including tracking changes, filtering relevant information, and establishing authenticity. By managing primary data effectively, metadata enhances its usability and aids in compliance with legal and regulatory standards in investigations.

In contrast, original format and native format refer to the way data is initially created and stored, rather than the organizing features that facilitate understanding. Metatag, while related to keyword identification in web content and documents, does not encompass the broader functionality that metadata offers in the realm of electronic discovery.
