Research Problems for Scalable Internet Resource Discovery University of Colorado at Boulder Research Problems for Scalable Internet Resource Discovery

Over the past several years, a number of information discovery and access tools have been introduced in the Internet, including Archie, Gopher, Net nd, and WAIS. These tools have become quite popular, and are helping to rede ne how people think about wide area network applications. Yet, they are not well suited to supporting the future information infrastructure, which will be characterized by enormous data volume, rapid growth in the user base, and burgeoning data diversity. In this paper we indicate trends in these three dimensions, and survey problems these trends will create for current approaches. We then suggest several promising directions of future resource discovery research, along with some initial results from projects carried out by members of the Internet Research Task Force Research Group on Resource Discovery and Directory Service.
