Metadata:- Metadata is data that provides information about other data. Data about data is called Metadata. There are many types of Metadata:

1.     Descriptive Metadata

2.     Structural Metadata

3.     Administrative Metadata

4.     Reference Metadata

5.     Statistical Metadata

Metadata was traditionally used in the card catalogs of libraries until the 1980s. Metadata was also used to describe digital data using metadata standards.

The first description of “Metadata” for computer systems is purportedly noted by MIT’s Centre for International Studies experts “David Griffel” and “Stuart Mclntosh” in 1967.

·   A the principal purpose of Metadata is to help users to find relevant information and discover resources.

·   Metadata also helps to organize electronic resources, provide digital identification and preservation of resources.

·   Metadata assists users in resource discovery by allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing resources, and giving location information. In many countries, the metadata relating to emails, telephone calls, Web pages, Video traffic, IP connections, and cell phone locations are routinely stored by government organizations.

·   Metadata is defined as the data providing information about one or more aspects of the data. It is used to summarize basic information about data which can make tracking and working with specific data easier.

·  Metadata can be stored and managed in a database, often called a metadata registry or metadata repository.

·   The term “Metadata” was coined in 1968 by Philip Bagley, in his book “ Extension of Programming Language Concepts”.


Types of Metadata:

1)    Descriptive Metadata: Descriptive metadata describes a resource for purposes such as discovery and identification. It can include elements such as title, abstract, author, and keywords, publishers, etc. Descriptive metadata is typically used for discovery and identification as information to search and locate an object.

2)    Structural Metadata: Structural Metadata is metadata about containers of data and indicates how compound objects are put together, for example how pages are ordered to form chapters of a book. It describes the types, versions, relationships, and other characteristics of digital materials. Structural metadata describes how the components of an object are organized.

3)    Administrative Metadata: Administrative Metadata refers to the technical information including file type, or when and how the file was created. Administrative Metadata can be categorized into the following two sub-categories:

I)   Rights Management Metadata: Rights Management Metadata explains intellectual property rights.

II)    Preservation Metadata: Preservation Metadata contains information to preserve and save the resources.

4)    Reference Metadata: Reference Metadata is information about the contents and  quality of Statistical data.

5)    Statistical Metadata: Statistical Metadata also called process data may describe processes that collect, process, or produce statistical data.

6)    Legal Metadata: Legal Metadata provides information about the creator, copyright holder, and public licensing.
