Abstract

This document defines the syntax used by the World-Wide Web initiative to encode the names and addresses of objects on the Internet. The web is considered to include objects accessed using an extendable number of protocols, existing, invented for the web itself, or to be invented in the future. Access instructions for an individual object under a given protocol are encoded into forms of address string. Other protocols allow the use of object names of various forms. In order to abstract the idea of a generic object, the web needs the concepts of the universal set of objects, and of the universal set of names or addresses of objects.

Introduction

This document defines the syntax used by the World-Wide Web

initiative to encode the names and addresses of objects on the

Internet. The web is considered to include objects accessed using an

extendable number of protocols, existing, invented for the web

itself, or to be invented in the future. Access instructions for an

individual object under a given protocol are encoded into forms of

address string. Other protocols allow the use of object names of

various forms. In order to abstract the idea of a generic object,

the web needs the concepts of the universal set of objects, and of

the universal set of names or addresses of objects.

A Universal Resource Identifier (URI) is a member of this universal

set of names in registered name spaces and addresses referring to

registered protocols or name spaces. A Uniform Resource Locator

(URL), defined elsewhere, is a form of URI which expresses an address

which maps onto an access algorithm using network protocols. Existing

URI schemes which correspond to the (still mutating) concept of IETF

URLs are listed here. The Uniform Resource Name (URN) debate attempts

to define a name space (and presumably resolution protocols) for

persistent object names. This area is not addressed by this document,

which is written in order to document existing practice and provide a

reference point for URL and URN discussions.

The world-wide web protocols are discussed on the mailing list www-

talk-request@info.cern.ch and the newsgroup comp.infosystems.www is

preferable for beginner's questions. The mailing list uri-

request@bunyip.com has discussion related particularly to the URI

issue. The author may be contacted as timbl@info.cern.ch.
