Abstract

A Uniform Resource Locator (URL) is a compact string representation

of the location for a resource that is available via the Internet.

This document provides guidelines for the definition of new URL

schemes.

1. Introduction

A Uniform Resource Locator (URL) is a compact string representation

of the location for a resource that is available via the Internet.

RFC 2396 [1] defines the general syntax and semantics of URIs, and,

by inclusion, URLs. URLs are designated by including a ":"

and then a "". Many URL schemes are already

defined.

This document provides guidelines for the definition of new URL

schemes, for consideration by those who are defining and registering

or evaluating those definitions.

The process by which new URL schemes are registered is defined in RFC

2717 [2].

2. Guidelines for new URL schemes

Because new URL schemes potentially complicate client software, new

schemes must have demonstrable utility and operability, as well as

compatibility with existing URL schemes. This section elaborates

these criteria.

2.1 Syntactic compatibility

New URL schemes should follow the same syntactic conventions of

existing schemes when appropriate. If a URI scheme that has embedded

links in content accessed by that scheme does not share syntax with a

different scheme, the same content cannot be served up under

different schemes without rewriting the content. This can already be

a problem, and with future digital signature schemes, rewriting may

not even be possible. Deployment of other schemes in the future

could therefore become extremely difficult.
