Abstract

The DNS (Domain Name System), which was designed as a network resource naming layer, is not able to serve today's Internet users naming needs anymore. Attempts to change the DNS to adapt to those needs, such as the IDN (Internationalized Domain Name) IETF effort,are not only proving themselves unsatisfactory in many ways, they are also limited by the nature of DNS itself. There is now strong consensus that the solution for naming for the Internet requires layers above DNS.  For example, John Klensin has advocated a multi-layered model that undertakes to address the naming needs of the modern Internet. In Klensin's model, the layer immediately above DNS is fully multilingual and user-friendly. It is expected that this layer will support a variety of distinct services. This document presents the requirements of one class of naming service called Keywords systems, of which there are several deployed today. These requirements are presented from the perspective of Internet users,for whom there exists no satisfactory standard naming system.

1.  Introduction

The Internet has evolved from a simple interconnection of networks to a global infrastructure supporting academic, personal, governmental,and commercial communications. As a result, the Internet's main naming system, the DNS, has seen its use change dramatically. As the number of names in demand has increased, so has the realization that there is a profound mismatch between a name meant to be used by humans and one meant to be used by applications. Because they have been the only names available for use on the Internet, domain names could not remain simply resource names, but rather were pushed to became the labels that every Internet user would ideally associate with the content they sought to access. That push has not happened smoothly. Attempts to change the nature of DNS names by internationalizing them do not solve the main problem of the awkwardness of DNS names in a versatile, multilingual, human-friendly naming scheme for the global Internet.
