Re: SOP wiki was: A Somewhat Critical View of SOP (Same Origin Policy)

Henry,
I believe that the wiki page should start by  writing use cases, and not re-explaning SOP cons and your technical vision. If you want to trigger collaborative thinking, thanks for exposing:
- Use case,
- What feature in your use cases can't be achieved with today's technical rules.

And then we will be able to have technical discussions about potentiel solutions.

Regards
Virginie

Thanks Virginie for the great idea of putting up this wiki. Mailing list
discussions are very educational if one follows them with great care, but
it is very difficult for people who jump in from the outside in mid conversation
or who are following from the sidelines to understand what if anything has
been gained by the discussion.

I have brought together a lot of what I have learnt about SOP with many
references to IETF and W3C specs, pointers to new evolutions in the webapp(sec)
groups, and discussion with community members on the wiki

  https://www.w3.org/Security/wiki/IG/a_view_on_SOP

This weekend I re-arranged the wiki into three pieces

1. Conceptual map : just to give an idea how work from privacy, identity,
security, logic, and other areas bear on the issue. There are still pieces
to be filled out here.

2. Exceptions to SOP:

  the more I look around the more I have found well documented and justified
exceptions to narrow understandings of SOP. This should give us some good raw
material for a later exploration of a theory of SOP.

3. Implications for Future standards.

  A third section on who SOP is bringing up issues for future requirements such as
WebPayments.

4. Theory of SOP

  Here I think we'll be able to bring together an extended theory of SOP
that makes sense of the exceptions, whilst showing how these tie into other elements of the conceptual spaces. My feeling is that a bit of work  in some very initial modal logic of belief contexts would help give a secure logical foundation.

I think this is taking shape. Of course there will be errors, improvements. It is not
complete, so feedback is welcome.

Henry
