Metadata is "data about data".
Two types of metadata are commonly distinguished:
- Structural metadata, about the design and specification of data structures or "data about the containers of data"
- Descriptive metadata about individual instances of application data or the data content
Metadata was traditionally in the card catalogs of libraries.
As information has become increasingly digital, metadata are also used to describe digital data using metadata standards specific to a particular discipline.
