Metadata
Metadata is data that describes other data. It provides context and additional information about a piece of data, such as its format, location, quality, and ownership. Metadata can be used to help organize and manage large collections of data, making it easier to find and use the data.
Metadata can be classified into several different types, including descriptive metadata, structural metadata, and administrative metadata. Descriptive metadata provides information about the content of the data, such as the title, author, and keywords. Structural metadata describes the structure of the data, including how it is organized and related to other data. Administrative metadata provides information about the data's ownership, security, and access controls.
Metadata can be stored in a variety of ways, such as in a separate metadata database, as part of the data file itself, or in a metadata standard such as Dublin Core, which provides a standardized set of metadata elements for describing a wide range of digital resources.
Metadata is used in a variety of applications, such as search engines, libraries, and archives. It is also used in data management and governance, helping to ensure that data is properly categorized, documented, and managed throughout its lifecycle. Overall, metadata is an important tool for managing and using data effectively, providing valuable context and information that can help users make sense of large and complex data collections.
