UMA Issues
by Justin Richer 15 Jul '15

15 Jul '15

As promised, I’ve documented and filed the various bugs in the UMA spec that I’ve found while trying to implement it: https://github.com/xmlgrrl/UMA-Specifications/issues/created_by/jricher <https://github.com/xmlgrrl/UMA-Specifications/issues/created_by/jricher> Most of these would require breaking changes to fix properly, so they’re not really targeted at UMA 1.0 errata in my personal opinion. Several of the issues cascade on one another: for example, fixing #153 as suggested in the ticket would solve a number of other issues simultaneously. — Justin

Draft minutes of UMA telecon 2015-07-09
by Eve Maler 09 Jul '15

09 Jul '15

http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-07-09 <http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-07-09> Minutes Roll call Quorum was reached. Minutes approval MOTION: Robert moves and Sal seconds: Approve the minutes of UMA telecon 2015-06-25 <http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-06-25> and read into today's minutes the notes of UMA telecon 2015-07-01 <http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-07-01>. APPROVED by unanimous consent. Call logistics Let's stick with our Skype-providing option and Eve will try and remember (everyone please help her) to put something in the join.me chat at the beginning of every call to remind join.me joiners to use the alternate dial-in, not the join.me dial. DONE! Obligations UMA trust, obligations, commitments, transactions, receipts, contracts, licenses... Most important use cases Prepare thoughts and questions for the meeting with Prof. Singh et al. the following day The question arose: How to bind UMA to existing legal structures. "Licensing" is the dominant approach used by lawyers. Does it work in UMA? Prof. Singh introduced some alternate terminology. DRM approaches are another approach. authorization (could be can or can't?) commitment (UMA obligation) prohibition sanction (like a fine) power Eve propose that a "license" model within UMA could look like this: (With some preconditions having been satisfied, such as client credentials being issued, etc.) RO authorizes RqP to access Resource Set(s) to use Scope(s) by adding authorization data to RqP’s Client’s RPT RqP exercises license by having Client access Resource Set(s) using Scope(s) RO is able to withdraw the license by revoking the authorization A challenge with the license model is active revocation. If it appears to be a license for five days, but then the RO revokes the license after two days, what happens? There are technical implications around caching vs. token introspection, checking of expiration periods, and so on (time-to-live management), and also business implications of RqP and client expectations. It could be the case that an access federation trust framework specifies both levels of expectations. If the RO suspects malfeasance, maybe all bets are off and then can revoke immediately. Tim has sent a document called "The New Ontologies - The Effect of Copyright Protection on Public Scientific Data Sharing Using Semantic Web Ontologies" to the list. The attraction here was the notion of machine-readable license language. By contrast, if Alice presents Bob with terms he has to agree to, she could point him to machine-readable terms (which could be the ontology content above), and a "contract" model could look like this: AS, on behalf of RO, offers RqP valuable (this is important) access under terms expressed by policy (the terms are going to result in, e.g., authentication, claims, and any other trust elevation parameters able to be supplied by the RqP) RqP accepts RO’s terms by conveying trust elevation parameters that meet policy — environmental, contextual, and heuristic factors are insufficient to indicate acceptance, while AAT acceptance may be a good indicator of pre-willingness to accept terms later on even when supplying claims implicitly through a client that pushes them silently AS, on behalf of RO, provides consideration by adding authorization data to RqP’s Client’s RPT If you standardize the claims, e.g. for the HIPAA-type "purpose of use", and especially if you standards resource types, the terms would be pretty clear in this case. But it's definitely a more complicated model. If you throw events that are machine-readable during the course of the protocol running, that starts to look like "consent receipts" or similar. Who's interested to meet with the researchers tomorrow? Eve will add Robert to the invite. AI status AI: Thomas: Review the charter for potential revisions in this annual cycle. AI: Eve: Review Marcelo Wikipedia comments and take next actions. AI: Tim: Expound on the licensing idea in email. AI: Sal: Investigate IP implications of formal liaison activities with other Kantara groups with the LC, and ultimately draft an LC Note as warranted. Let's discuss this at the next LC call. AI: Gil: Edit the UIG to add Ishan's content and excerpt it for Eve to add to the FAQ, pointing everyone to the UIG. AI: Sal: Fill out IDESG form to have UMA adopted as a recommended standard for use in the IDESG framework. PROGRESSING. There are multiple steps. He has gone through the process with OAuth and OIDC already. AI: Mike: Rework UIG section on organizations as ROs and RqPs. AI: Eve: Update GitHub. AI: Maciej: Write as many sections for the UIG as he can. AI: Justin: Write a UIG section on default-deny and race conditions. Attendees As of 1 Jul 2015 (pre-meeting), quorum is 7 of 13.

join.me dial-in vs. Kantara "line C" and Skype for our meetings
by Eve Maler 02 Jul '15

02 Jul '15

It was noted on the recent call join.me has grown in functionality since we started using Thomas's paid account, and there is now a dial-in number displayed that we are not using; instead we use Kantara's "line C", which comes with a Skype option. Should we continue splitting up the screenshare and the dial-in (and warn people to try and avoid confusion), which has the advantage of offering the Skype option, or align the two so as to fully avoid any confusion? Please express your opinion here (and Thomas, please let us know if this impacts the costs associated with your account), and we will decide on next week’s call. (Please note the potential confusion when dialing in to the normal number next time!) Eve Eve Maler | cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl | Calendar: xmlgrrl(a)gmail.com

Notes from UMA telecon 2015-07-01
by Eve Maler 02 Jul '15

02 Jul '15

http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-07-01 <http://kantarainitiative.org/confluence/display/uma/UMA+telecon+2015-07-01> Minutes Roll call Quorum was not reached (not that it is generally expected in this specially scheduled call). Minutes approval Deferred. Logistics It was noted that join.me has grown in functionality since we started using Thomas's paid account, and there is now a dial-in number displayed that we are not using; instead we use Kantara's "line C", which comes with a Skype option. Should we continue splitting up the screenshare and the dial-in (and warn people to try and avoid confusion), which has the advantage of offering the Skype option, or align the two so as to fully avoid any confusion? Eve will ask on the list and we will decide by next time. Upcoming event in Singapore and UMA-XACML interest Kuppinger Cole conference in Singapore in November: Gil proposes a panel that freshens up the discussion about XACML. E.g., how does XACML plug into UMA? Could it be part of the panel, or maybe be a separate session? And relatedly, might there be interest in developing a profile of XACML for UMA, a profile of UMA for XACML, or both? Eve had written some thoughts following on to Hal Lockhart’s white paper on an XACML profile for OAuth policies, which could provide some food for thought. Eve will ping her colleague Allan Foster, who is Singapore-based, for interest in co-presenting. Colin is interested in the topic; he probably can’t attend if not speaking. Justin would be interested to attend the conference if someone is willing to send him! Gil’s conclusion with his colleague was that XACML policy, or even portions of it, in combination with UMA is a good idea. How would an OASIS/Kantara split of activity work? An active liaison would probably be a good idea. As long as text isn’t quoted, and “incorporating by reference” is okay, then a profile on either end is probably acceptable. The REST profile for XACML was published about six months ago. The UMA FAQ mentions it. Justin’s demo at the HIMSS conference protected XACML policy as an UMA resource! That’s a nice new one. UMA issue backlog Justin has been implementing UMA against an existing OAuth and OpenID Connect server and has been collecting ideas for things that could be optimized or fixed or cleaned up. He’s been sitting on them so far, partly to be sure he understands them fully, and partly not to upset the V1.0 apple cart. His items/ideas include, for example (he has 16): “dynamic endpoint” config data naming (vs. “registration endpoint”) “rpt endpoint” being separate from the ordinary OAuth token endpoint doing an ordinary OAuth token grant, which would allow the client to specify the scopes it wants, which it can’t do now Eve has been thinking about one, which is: Letting an RS register more than one requested permission rather than a single one Binding Obligations Sociotechnical Systems conversation, commitments, and obligations: Eve, Tim, and others are meeting with Professor Munindar Singh and his colleagues on July 10 at 9am PT. If anyone is interested to join the call, drop Eve a line. Eve will send a link to Prof. Singh’s extended abstract and other papers to the list. NZ government POC Colin describes the ongoing NZ government POC. The first sprint is to stand up an UMA out-of-the-box scenario. Governments, like any large enterprise, have issues with delegations: a user wants to delegate access to others out of their account, and there are also “headless” use cases where the user is not present. Colin is not directly involved, but is observing from the side. He’ll give updates as he can. AIs AI: Thomas: Review the charter for potential revisions in this annual cycle. AI: Tim: Expound on the licensing idea in email. AI: Sal: Investigate IP implications of formal liaison activities with other Kantara groups with the LC, and ultimately draft an LC Note as warranted. AI: Gil: Edit the UIG to add Ishan's content and excerpt it for Eve to add to the FAQ, pointing everyone to the UIG. Update: Will try to do this weekend. AI: Sal: Fill out IDESG form to have UMA adopted as a recommended standard for use in the IDESG framework. AI: Mike: Rework UIG section on organizations as ROs and RqPs. AI: Eve: Update GitHub.
