Historical note: in the early/mid 1980s, the IAB and its US government funders were very concerned with the name lookup problem. They realized that the DNS was designed for host name lookup. The government tasked the IAB with developing a "yellow pages" service to complement the "white pages" of the DNS. But this effort got wrapped entirely around the complexity of X.500, a top-down standard with little/no running code, and died. This will all be found in early IAB meeting minutes.
