Metadata describes and gives information about other data. It provides structure, context and meaning to content ̶ making it findable and understandable to both computers and humans. Metadata is essential to the use of XML and DITA.
The three primary types of metadata are Structural, Administrative and Descriptive.
Some examples of metadata include the time and date of content creation, author of the content, and descriptive keywords.
- Describe specific parts of content components ̶ such as title, subject, keywords or audience
- Set permissions or expiry dates on certain pieces of content
- See in what ways the content has been altered
