Subject: Intermediary I-cloud "requirements" draft
Here are some of the goals (not axioms!) that we have been
discussing for building various I-clouds. It is too early for axioms IMO. Routing a. intermediary cloud can remap an original
sender’s message types to a new recipient without the original sender
changing its configuration b. intermediary should strive to maintain
transparency by not modifying message excessively Transparency aspects a. original signatures remain unbroken (and probably
need to be designed to withstand some I-cloud modifications) b. reliability assurances are preserved to the extent
possible – end to end if possible c. data confidentiality is preserved (and may also
need to be designed/constrained to enable I-cloud presence) Endpoints a. Core conformance endpoints (original sender and
ultimate receiver) should not need to modify behavior [at all | excessively]. b. MSH intermediaries will have special conformance
profile SOAP intermediary a. A MSH intermediary is also a SOAP intermediary,
but may be constrained in certain ways by SOAP (probably underconstrained by
SOAP Intermediary rules) b. A MSH SOAP intermediary can be targeted by headers
and those headers removed. c. Addition of headers must be carefully scrutinized
with respect to Transparency aspects. |
