A Uniform Resource Locator (URL) is a compact string representation
of the location for a resource that is available via the Internet.

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

order to accommodate new Internet protocols and/or procedures.
A registration process is needed to ensure that the names of all such
new schemes are guaranteed not to collide. Further, the registration
process ensures that URL schemes intended for wide spread, public use
are developed in an orderly, well-specified, and public manner.
This document defines the registration procedures to be followed when
new URL schemes are created. A separate document, RFC 2718,
Guidelines for URL Schemes , provides guidelines for the creation
of new URL schemes. The primary focus of this document is on the

2.0 URL Scheme Name Registration Trees
In order to increase the efficiency and flexibility of the URL scheme
name registration process, the need is recognized for multiple
registration "trees". The registration requirements and specific
registration procedures for each tree differ, allowing the overall
registration procedure to accommodate the different natural
requirements for URL schemes. For example, a scheme that will be
recommended for wide support and implementation by the Internet
community requires a more complete review than a scheme intended to
be used for resources associated with proprietary software.
The first step in registering a new URL scheme name is to determine
which registration tree the scheme should be registered in.
