This is a new thread built from "Revisiting the photo sharing example (a driving use case for the creation of OAuth)" Justin, > So what I’m saying is that what you’re defining as part of the RS was > (in Oauth) defined as a function of the AS. > As such, I contend that it needs to be its own separate functional > role, neither AS nor RS. I don't see that as separate roles, but as two different kinds of interactions with the same entity. > That way it could be fulfilled by an entity either closely tied to the > AS or closely tied to the RS, as appropriate. > It would give us more flexibility to talk about the patterns. Nevertheless, such a possibility should be explored in more depth. In my response to Dick I wrote: A set of a choices should be presented by the RS to the Client in a standardized way. The choices made by the user should be locally recorded by the Client, hence the RS does not need to be informed of these choices. The RS will only know the end result of these choices when/if it gets back one or more access tokens. Human to software interactions should be part of the protocol. RS to Client: a set of choices Client to RS: Done (choices have been done by the user). For a RS, before performing a given operation, the RS should specify to the User how many access tokens would be required, from which ASs they could be obtained and which types of attributes these access tokens should contain. For an AS, a key question would be whether some choices would be presented by the AS to the Client in a standardized way ? I don't know. What would be such choices ? I let Dick, yourself or someone else respond but I wonder that such choices could be presented by an AS to a User (through the Client) in a standardized way.
