In order to protect creative development of new services, there is an extensible class of services for which no parameter package semantics common across services may be assumed.

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


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


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

behalf in a relatively transparent way. Without such a method,

transparent and widely distributed, open information access on the

Internet would be difficult if not impossible.

2.1 Defining the General Resource Locator

The requirements listed in this document impose restrictions on the

general resource locator. To better understand what the Internet

resource locator is, the following general locator definition

provides some contrast.

Definition: A general resource locator is an object

that describes the location of a resource.

This definition deliberately allows many degrees of freedom in order

to contain the furthest reaches of the wide-ranging debate on

resource location standards. Vast as it is, this problem space is a

useful backdrop for discu...
