Metadata what is that ?

Metadata

(Greek: meta‐+ Latin: data ʺinformationʺ),

Literally translated :‐

ʺData about Dataʺ

It is information that describes another set of data.

A common example is a library catalogue card, which contains data about the contents and location of a book:

It is data about the data in the book referred to by the card.

Other common contents of Metadata include the source or author of the described dataset, how it should be accessed, and its limitations.

Other machine generated data about data, such as the reversed index created by a free‐text search engine is generally not considered as Metadata.

Another important type of data about data is the links or relationship among data.

Some Metadata scheme attempts to embrace this concept (Such as Dublin Core element link).

Since Metadata is also data, it is possible to have ʺMetadata of the Metadata of Dataʺ.

The Metadata which is embedded with content is called embedded Metadata.

A data repository typically stores the Metadata detached from the data.
