Metadata

Metadata refers to structured reference data that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource. Essentially, it is data about data. For instance, in a library catalog, the metadata for a book might include the title, author, ISBN, and subject headings. In digital contexts, metadata can include information like file size, format, creation date, and author. Metadata plays a crucial role in data management, enabling efficient organization, search, and retrieval of information. It enhances the usability and accessibility of data, providing context and meaning. By standardizing how information is described, metadata facilitates interoperability and integration across different systems and platforms. This structured approach to data management is vital in fields ranging from libraries and archives to digital asset management and information technology.
