Internet resource discovery at the University of Colorado

The author discusses aspects of Internet´s resource discovery problem: how users specify searches, the difference between discovering classes of resources and locating appropriate instances, system-management problems that can be cast as global state discovery searches, issues involved with characterizing resources and with the efficient distribution of characterizing information, and social issues, especially privacy. Results of efforts to address these problems as part of the Networked Resource Discovery project at the University of Colorado are presented. These efforts use a variety of experimental approaches, including prototype systems, network measurement studies, and simulation studies.<>
