1.0 Introduction
1.1 Overview of the TISDAG project
As described in more detail in [TISDAG], the original intention of
the TISDAG project was to provide the infrastructure for a national
whitepages directory service. To be effective, such an
infrastructure needed to address the concrete realities of end-users'
existing client software, as well as the needs of information
providers ("Whitepages Directory Service Providers" -- WDSPs). These
realities include the existence of multiple protocols (so-called
directory service access protocols, as well as more general Internet
application protocols such as HTTP and SMTP). The project was also
sensitive to the fact that WDSPs have many good reasons for being
reluctant to relinquish copies of their subscribers' personal data.
