Open Archives Initiative to release new Metadata Harvesting specification Scott Wilson, CETIS staff
April 12, 2002
The Open Archives Initiative (OAI) has announced that Version 2.0 of the Metadata Harvesting Protocol will be released on June 1st, 2002.
A number of organisations are taking part in early testing of the new specification, including the British Library, the Library of Congress and NASA. Version 2.0 adds a number of new features, including detection of duplicate entries, additional flow control attributes, and improved date and time handling.
The Metadata Harvesting Protocol is designed to allow search engines and portals to "harvest" metadata from digital repositories. This enables users to search multiple libraries from a single search interface, for example.
The protocol is intended to be simpler to implement and narrower in scope than the more comprehensive Z39.50 library protocol, allowing repository owners to "open up" their metadata for searching without substantial amounts of coding.
