       Functional Recommendations for Internet Resource Locators

Status of this Memo

   This memo provides information for the Internet community.  This memo
   does not specify an Internet standard of any kind.  Distribution of
   this memo is unlimited.

1. Introduction

   This document specifies a minimum set of requirements for Internet
   resource locators, which convey location and access information for
   resources.  Typical examples of resources include network accessible
   documents, WAIS databases, FTP servers, and Telnet destinations.

   Locators may apply to resources that are not always or not ever
   network accessible.  Examples of the latter include human beings and
   physical objects that have no electronic instantiation (that is,
   objects without an existence completely defined by digital objects
   such as disk files).

   A resource locator is a kind of resource identifier.  Other kinds of
   resource identifiers allow names and descriptions to be associated
   with resources.  A resource name is intended to provide a stable
   handle to refer to a resource long after the resource itself has
   moved or perhaps gone out of existence.  A resource description
   comprises a body of meta-information to assist resource search and
   selection.

   In this document, an Internet resource locator is a locator defined
   by an Internet resource location standard.  A resource location
   standard in conjunction with resource description and resource naming
   standards specifies a comprehensive infrastructure for network based
   information dissemination.  Mechanisms for mapping between locators,
   names, and descriptive identifiers are beyond the scope of this
   document.

2. Overview of Problem

   Network-based information resource providers require a method of
   describing the location of and access to their resources.
   Information systems users require a method whereby client software
   can interpret resource access and location descriptions on their
