metainformation
Information about information
Metainformation is information about information—data that describes, organizes, or provides context for other data.
A book's table of contents is metainformation about the chapters.
File properties like creation date and author are metainformation about the document.
The library catalog contains metainformation about every item in the collection.
The prefix meta- signals this self-referential quality.
