I think we can agree that the trust (the IETF) cannot give away more
rights than it has obtained from the contributor (however much they are,
and if that's "everything related to copyright" that's fine).
I can think of no reason why the trust (IETF) should ever offer less
than what the contributor has allowed - that would be entirely contrary
to the purposes for which we need licences from the contributor in the
first place - the aim is to make sure that the code is available with
as few restrictions as possible, having the trust add restrictive licence
terms would be counter productive (regardless of what those terms are).
The working group's non-consensus on this point is documented in section
4.4 of RFC 5377:
4.4. Rights Granted for Use of Text from IETF Contributions
There is no consensus at this time to permit the use of text from
RFCs in contexts where the right to modify the text is required. The
authors of IETF Contributions may be able and willing to grant such
rights independently of the rights they have granted to the IETF by
making the Contribution.
If all that's reasonable, then it follows that licence in == licence out,
and while it is possible that might be change from time to time, the
change must be to the licence in first, and that then means that the
licence out change affects only those RFCs published after the change,
one earlier must still be on the old terms (if the change was broadening
the licence to the IETF, then no earlier submission by anyone would be
broader in the new way, and so the outgoing licence could not be the new
broader form, if the change is to narrow the rights given to the IETF,
that will necessarily narrow what the IETF can grant users of the code,
but there's no reason it should restrict the rights granted under older
submissions, that were published with a broader grant to the IETF.
The "RFC 5378" license to the trust allows, for instance, the Trust to
grant the right of copying small snippets of code without attaching the
full BSD license to them. The current TLP does not give that right.
Incoming and outgoing rights for code are currently different.
So, I remain fairly convinced that there's no need at all to ever
make (or pretend to make) any change which would ever require updating all
past RFCs, a change should only ever affect future publications.
I'm fairly convinced that there will come a time when we need to
relicense text that was previously licensed by the Trust in a way that
is more liberal than the current text of the TLP allows for (while
remaining within the scope of rights granted to the trust).
That's why I yell so much on this matter.
Harald
