DEFINITION
Metadata describes various attributes of information objects and gives them meaning, context, and organization. Descriptive metadata theory and practice is a familiar area for many as its roots are embedded in the cataloging of print publications. In the digital realm, additional categories of metadata have emerged to support navigation and file management.

METADATA TYPES AND THEIR FUNCTIONS
For practical purposes, the types and functions of metadata can be classified into three broad categories: descriptive, structural, and administrative. These categories do not always have well-defined boundaries and often exhibit a significant level of overlap. For example, administrative metadata may include a wide range of information that would be considered descriptive and structural metadata.
