According to Ralph Kimball, metadata can be divided into three categories: technical metadata (or internal metadata), business metadata (or external metadata), and process metadata.
A metadata standard defines how metadata should be structured and applied across different systems. Two widely recognized metadata standards are Dublin Core and ISO 19115.
Metadata refers to data that provides information about other data. It describes the structure, content and characteristics of a file, document, image or dataset, helping users and systems understand and manage data more effectively.

What is Metadata? Metadata is often described as “data about data,” providing information about a data item, file, or collection that helps us understand, find, and use it effectively. Metadata can be thought of as a label or a set of properties attached to data that enriches its context and usability without changing the data itself.
