Metadata is simply data that describes other data. In other words, it gives you information about a piece of information. For example, when you take a photo on your phone, the metadata includes information such as the date and time it was taken, the location, and the type of camera used. Metadata is used in many different contexts, such as in libraries to help organize and categorize books, in music streaming services to provide information about songs and albums, and in search engines to help users find relevant results. Overall, you can think of metadata as helpful information that makes it easier to understand or find something.
