In contrast to the content of the data, such as the message's text or the image itself, metadata is defined as "data that offers information about other data".
Metadata can take many different forms, including:
Descriptive metadata is data that describes a resource.
It is employed for both identification and discovery. Such components as the title, abstract, author, and keywords are included.
Structural metadata describes data containers and describes the construction of complex things, such as the arrangement of pages into chapters. It explains the many kinds, iterations, connections, and other features of digital content.
Administrative metadata is the data used to administer a resource, such as the resource type, permissions, and the circumstances surrounding its creation.
