Metadata is data that describes other data. They summarize basic information about that other data, making it easier to find and work with specific instances of data. For example, author, creation date, modification date, and file size are among the most basic document metadata. In addition to document files, metadata is used for images, videos, spreadsheets, and web pages. Effective metadata management is an essential part of robust and flexible big data ecosystems, enabling organizations to efficiently manage their data assets and make them available to data scientists and other analysts.
