This document discusses metadata harvesting tools. It defines metadata as "data about data" and explains that metadata harvesting is the process of gathering metadata from distributed repositories into a combined data store. The document outlines the need for metadata harvesting, including single platform discovery, easy sharing between libraries, and archiving. It provides examples of metadata harvesting services in India and tools used, and discusses considerations like metadata standards and library standards.

3. Introduction to Metadata
 Metadata can be defined as "data about data" describe the content,
quality, condition, and other characteristics of data. Metadata is vital in
helping potential users to find needed data and determine whether a data
set will meet their needs before they spend the time and money to obtain
and process it.

4. Example of Metadata
Element name Value
Title: Web catalogue
Creator: Dagnija McAuliffe
Publisher: University of Queensland Library
Format: Text/htm

5. Definition of Metadata
 “ Data that serves to provide context or additional information about
other data. for example, information about the title, subject , author,
typeface, enhancements, and size of the data file of a documents
constitute metadata about that document. It may also describe the
conditions under which the data stored in a database was acquired, its
accuracy, data, time, method of compilation and processing, etc.”
According to : http://www.businessdictionary.com/definition/metadata.html

6. Need of Metadata
Metadata is a systematic method for describing resources
and thereby improving access to them.
The primary aim of metadata is to improve resources
discovery. Resource documentation
 Resource selection, evaluation and assessment
 Resource identification and location
 Improving the quality and quantity of search result
 Electronic commerce to encode prices, term of pay, etc.
 Protecting instinctual property rights

7. Types of Meta Data
 Administrative Meta Data
 Descriptive Meta Data
 Structural Meta Data
 Preservation Meta Data
 Right Management Meta Data

8. What is Metadata Harvesting ?
 Harvesting: In the Open Archives Initiative context, harvesting refers
specifically to the gathering together of metadata from a number of
distributed repositories into a combined data store.

Open Access works are scattered across many disciplinary archives, institutional e-print archives,
institutional repositories and open access journals. Therefore, it is difficult for users to locate all
needed works on a particular subject.

Library related standards: Considerations
 Metadata Standards
 Some of the metadata standards available are MARC, MARC21, Dublin Core,
UK MARC (now transformed to marc21), etc. MARC21 is the latest standards
in term of metadata. The first level metadata elements of MARC are:
 Leader and Directory
 Control Fields 001-008
 Number and Code Fields (01X-04X)

Conclusion
 Metadata is a key part of the information infrastructure necessary to help
create order in the chaos of the Web, infusing description, classification,
and organization to help create more useful stores of information. OAI
metadata harvesting offers a new bridge to bring new innovation in
networked information services and applications, out of the research
community more rapidly
