Which of the following is a key component of a metafile?

In metadata management, a metafile bundles information that describes data assets so they can be understood and used correctly. The most essential piece is the data dictionary, because it provides precise definitions for each data element—its name, data type, format, permissible values, and meaning. This creates a common vocabulary that enables data stewards, analysts, and systems to interpret data consistently, enforce validation rules, and ensure uniform usage across applications. A data dictionary can also capture who owns the data, where it comes from, and how elements relate to one another, which enhances traceability and data quality. System logs document events and operations, not the definitions of data elements. A data warehouse is a repository for storing integrated data, rather than metadata describing the data elements themselves. A data science model is an analytic artifact built from data, not metadata about the data's structure.
