Subject: about message authorization
I think we can distinguish two authorization issues,
the second one being more a way to prevent errors:
Proposal for (2): Associate the claimed MPF with “readable”
information in a Pull signal, that can be used for a consistency check: - P-mode associated with a PullRequest may contain –
in addition to the MPF - the eb:From that is also associated with this Pull MEP
(i.e. generally matching the eb:To of the pulled message). - a Pull signal claiming this MPF must then also insert an
eb:PartyInfo that matches the eb:From associated with this MPF. - corner case: several eb:From share same receiving
MSH (i.e. different eb:To values in messages to be pulled from the same MPF). Because
the role of the eb:From in the pull is just authorization of the MPF –
not selection within the MPF - , no need to use all the possible eb:From values
– just one that is authorized. -Jacques |
