Final Charter for Working Group

This working group exists for the purpose of creating two documents:
The first document, a BCP RFC, will be the process for registering
new URL schemes. The second document, an Informational RFC, will be
a guideline for the creators of new URL schemes. The purpose of this
guideline will be to help ensure that new URL schemes:

  • Consistently implement the general syntax of URLs as specified in
    URL Generic Syntax and Semantics RFC.
  • Are compatible with existing URL schemes.
  • Have clearly specified character encoding rules.
  • Have a well defined set of operations specified for them.
  • Properly address security considerations.

The following issues are considered beyond the scope of this working
group and shall not be addressed by it:

  • Modifications to the URL Generic Syntax and Semantics RFC.
  • Specific URL schemes, previously proposed or not, except as test
    cases for the guidelines document.
  • UR* schemes other than URLs.

Justification for working group:

RFC 1738 defined URL schemes for a number of protocols popular at the
time that it was written. Many URL schemes for protocols not addressed
in RFC 1738 have been proposed since the publication of that RFC.

Due to the absence of guidelines for the development of new URL schemes,
some of these recently proposed schemes lack completeness. Further,
while some of these schemes are now on the standards track, no mechanism
for the registration of these new schemes has yet been specified.

The output of this working group is needed in order to help ensure the
overall integrity and consistency of URLs in the future.
