Metadata is data about other data. Any structured information which's purpose is to define a specification of any form of data is referred to as metadata.
"An item of metadata is a relationship that someone claims to exist between two entities".
"Think of metadata as data which removes from a user (human or machine) the need to have full advance knowledge of the existence or characteristics of things of potential interest in the environment".
At first the term metadata was used for digital data exclusively, but nowadays metadata can apply to physical data as well as digital one. Catalogues, inventories, registers and other similar standardised forms of organising, managing and retrieving resources contain metadata. Metadata can be stored and contained directly within the file it refers to or independently from it with the help of other forms of data management such as a DAM system.
The more metadata is assigned to an asset the easier it gets to categorise it, especially as the amount of information grows. The asset's value rises the more metadata it has for it becomes more accessible, easier to manage, and more complex.
Structured metadata can be shared with open protocols like OAI-PMH to allow further aggregation and processing. Open data sources like institutional repositories have thus been aggregated to form large datasets and academic search engines comprising tens of millions of open access works, like BASE, CORE and Unpaywall.
