Metadata

What is Metadata?

Metadata refers to data that describes other data. It provides information about the characteristics of a particular piece of data, such as its format, size, author, creation date, and location.

For example, metadata for a photograph might include the date and time it was taken, the camera model and settings used, and the location where the photo was taken. Metadata for a document might include the author's name, the creation date, the file type, and the file size.

Metadata is often used to help organize and manage large collections of data, such as digital libraries or archives. It can also be used to help search engines and other software applications index and retrieve information more effectively.
