What is Metadata?
“Metadata is data that describes other data. Metadata summarizes basic information about data, which can make finding and working with particular instances of data easier. For example, author, date created and date modified and file size are very basic document metadata. In addition to document files, metadata is used for images, videos, spreadsheets and web pages.” Source: TechTarget
