Metadata Harvesting and
the Indexing of the Web

Wednesday, February 14 , 2001
Building 3 Auditorium - 3:30 PM

(Refreshments at 3:00 PM)


Goddard's Office of the Assistant Director for Information Sciences and Chief Information Officer announces the third GSFC Information Sciences and Technology (IS&T) Colloquium presentation of the Spring 2001 Series. Dr. Clifford Lynch, Executive Director of the Coalition for Networked Information (CNI), will speak on the topic, Metadata Harvesting and the Indexing of the Web. Search engines have been used to index the web for a number of years now; however, they suffer from very real limitations, including the inability to provide access to content that is not manifest as static HTML pages on the web. Recently, there have been important developments in working standards for metadata harvesting (the Open Archives Initiative, see which offer interfaces that sites can use to reveal metadata about digital objects that they house. These developments create very interesting opportunities for indexing more of the content available on the web, but also raise complex questions about the nature of the support infrastructure that needs to be developed, including registries and trust and reputation management tools. Dr. Lynch's talk will discuss some of the issues involved in web indexing today, provide a status report and summary of the Open Archives Work, and speculate about directions in infrastructure and applications development.

Clifford A. Lynch has been the Director of the Coalition for Networked Information since July 1997. CNI, jointly sponsored by the Association of Research Libraries and Educause, includes about 200 member organizations concerned with the use of information technology and networked information to enhance scholarship and intellectual productivity.
