What are metadata?
Metadata are structured data which describe the characteristics of an object or resource. They share many similar characteristics to the cataloguing that takes place in libraries, museums and archives. The term "meta" derives from the Greek word denoting a nature of a higher order or more fundamental kind.
A metadata record typically consists of a number of pre-defined elements representing specific attributes of a resource, and each element can have one or more values.
Each metadata schema will usually have the following characteristics:
minimum number of elements required to facilitate the discovery of document-like objects in a networked environment (eg Internet). Currently 15:

Intellectual Property: Author/Creator, Publisher, Contributor, Rights
Electronic/Physical Manifestation: Date,Type, Format, Identifier

Different approaches to understanding:
Statistical metadata is here and it is already changing the way people locate and make sense of data but it does not yet support most use cases of interest to social scientist. What we will need to move forward is:
