metadata
n 1: data about data; "a library catalog is metadata because it
describes publications"

/me't*-day`t*/, or combinations of /may'-/ or
(Commonwealth) /mee'-/; /-dah`t*/ (Or "meta-data") Data about
{data}. In {data processing}, metadata is definitional data
that provides information about or documentation of other data
managed within an application or environment.

For example, metadata would document data about {data
elements} or {attributes}, (name, size, data type, etc) and
data about {records} or {data structures} (length, fields,
columns, etc) and data about data (where it is located, how it
is associated, ownership, etc.). Metadata may include
descriptive information about the context, quality and
condition, or characteristics of the data.

A collection of metadata, e.g. in a {database}, is called a
{data dictionary}.

Myers of {The Metadata Company} claims to have coined the term
in 1969 though it appears in the book, "Extension of
programming language concepts" published in 1968, by {Philip
R. Bagley}. Bagley was a pioneer of computer document
retrieval. "A survey of extensible programming languages" by
Solntsseff and Yezerski (Annual Review in Automatic
Programming, 1974, pp267-307) cites "the notion of 'metadata'
introduced by Bagley".
