This section provided an introduction to the concept of meta-data.

Some of the key points:

    • Meta-data is information about what something is or contains. The “something” might be a physical object such as a book or a can of soup, or a digital object such as online content.


    • The phrase often used to explain meta-data — data about data — simply means descriptive information about something.


    • Meta-data may be either attached to the thing it describes, or stored in another place, or both.
