We are conducting an experiment that obtains descriptions of CCSO name servers [Dorner and Pomes, 1992]. Currently, there exist approximately 300 institutions that use the CCSO protocol, each with its own database manager. The servers provide various data about people in their institutions. Aside from the validation of our approach to obtaining descriptions, the results of the experiment will be significant for two reasons. First, given the mappings we will be able to provide the first large scale white pages service that is completely based on knowledge representation methods, thereby showing the utility of knowledge representation in this problem. Second, the mappings obtained (which will be validated with the site managers) will provide a first test data set on which researchers in the field can make meaningful comparisons of their methods for obtaining descriptions.
