Agenda
- Roll call
- Approve minutes of UMA telecon 2016-10-13, 2016-11-03
- Logistics for upcoming meetings (calendar) and 2016 roadmap check-in
- Next week: WG meeting on Fri Nov 18 at 9am PT after legal call instead of Thu Nov 17
- Week after: no WG or legal meeting due to US holiday
- Work on UMA.next issues – Core is up to 06 and should be up to 07 well before the meeting – please review changes ahead of time if possible
- The following changes affect syntax:
- Removed config data to declare pat and rpt profiles supported (as agreed last time)
- requesting party claims endpoint --> claims interaction endpoint (language that affects syntax in endpoint config data )
- resource set --> resource (language that affects syntax in endpoint config data and token introspection returned object format)
- New AS-to-client invalid_scope error (because a client can now ask for scopes)
- Set math: See 9-29 and 10-6, and the email thread – including...
- What scopes should the client ask for, and why? (E.g., least-privilege rationale.) What should the mechanism be for asking for scopes for specific protected resources?
- What permissions should the RS request on behalf of the client, and why?
- pat_grant_types_supported: My proposal was to remove it. Any further discussion?
- claim_token_profiles_supported: My proposal was to keep this profiling mechanism, but clean it up and provide two actual profiles or at least credible examples, say, for OIDC ID tokens and SAML assertions. Discussion?
- uma_profiles_supported: My proposal was to keep this profiling mechanism, but figure out seriously if the extensibility profiles are doing the right job, and include credible examples of extensions and not just extensibility profiles. Discussion?
- Is step-up auth the way it was conceived in UMA1 hunky dory according to the claims collection mechanism in UMA2?
- Is the (client) registration endpoint's name correct according to the naming pattern used in UMA, and also OAuth and OIDC?
- The following changes affect syntax:
- See the latest swimlane

Logistics
We're ON for Thu Nov 10 – regrets from Justin, Andi is unsure.
We need to MOVE our Thu Nov 17 meeting to 9am (usual hour) Fri Nov 18 – regrets from Cigdem, Domenico.
We're NOT MEETING Thu Nov 24 or Fri Nov 25 because of the US Thanksgiving holiday.

Work on UMA.next issues
"Authorization process": The definition could potentially be improved by breaking the first sentence into two. The second sentence could focus on risk management. Can we define "trust" formally somehow as managing risk? Do we need "trust elevation" anymore? This is a live thread in email. Is the equation "The RO only authorizes access within their risk appetite/tolerance"? Maybe this is where we could point off to the UMA Legal work because it's a complex equation and the RO isn't the only party with risk and liability. Robert notes that part of decision is how you make a good decision. A technical spec's job isn't to describe all of this, but it could point off to other resources that go into it.
"Authorization process: The process through which the client obtains an RPT from the authorization server in order to access a protected resource. The process has two activities, and these can iterate. One activity is assessing claims and other contextual factors against the resource owner's policy conditions. Another is is collecting claims, which can include both claims pushed from a client and interactively gathered from a requesting party.
Suggestion to Domenico for his new flowchart: Try switching input and actor bands, and adding an actor so there's always two. Let's be sure that it's "technically accurate" as much as possible, assuming developers will take it seriously. Andi suggests it will be used more "generically", so maybe we can use it more at a 50K foot level.
Regarding "token profiling goes poof": Medication/read 22354546 read
Regarding the "*supported" options in the config data: Both Justin's and Cigdem's implementations implement and ignore them! Is there any dissent to pulling pat_profiles_supported and rpt_profiles_supported?
Instructions:
- Sec 3.5.4: "The fifth error response, need_info, begins or continues..."
- Redefine "authorization process" through as two activities/states, and be sure to incorporate "client identity" and any other contextual factors (we used to call this "RqP-independent").
- Undo the "token profiling goes poof" and reconstitute the actual introspection response part; make use of 7662 mandatory.
- Remove pat_profiles_supported and rpt_profiles_supported
AI: Eve: Send separate email threads about all the other "*supported" config data fields and rationales pro and con.
