During the exhibition, there will be an opportunity for visitors to discuss the proposed plans with the teams at UK & European, as well as with the architects Mountford Pigott, landscape architects Bradley Murphey Design and DP9
Arc has been deployed in a number of environments and has served as the basis for many other OAI-PMH projects, including Archon, Kepler, NCSTRL, and DP9. In this article we review the history of OAI-PMH and Arc, as well as some of the lessons learned while developing Arc and related OAI-PMH services.
We will discuss the Archon project for building value-added services to take advantage of rich metadata beyond Dublin Core (DC) (Weibel & Lagoze, 1997); the DP9 service to allow general search engines (Google, Yahoo, etc.) to index OAI-PMH compliant collections; and the recently funded Andrew Mellon Foundation DL Grid project for building a high-performance federated search service.
Archon is a project we launched in response to the problem of how to build rich service based on complicated metadata; DP9 is an effort to make OAI-PMH repositories open to general Web crawlers; and the DL Grid project addresses the scalability problem of a large metadata harvesting system by using DL Grid technology.
DP9 is an open-source gateway service that allows general search engines (for example, Google, Inktomi, etc.) to index OAI-PMH-compliant archives (Liu, Maly, Zubair, & Nelson, 2002).
DP9 solves these problems by defining persistent URLs for all OAI-PMH records and dynamically creating a series of HTML pages according to a crawler's requests.
