You can find a description of the overall User-Managed Access proposition here: http://tinyurl.com/umafaq.
Part of the UMA WG's work is overtly technical, and part of the work explores other layers of the BLT (business-legal-technical) sandwich. The documents here reflect work in these other areas, many produced by our ad hoc "legal subgroup".
The overall goal of the subgroup: Accelerate adoption and reduce inhibitors in a business context.
The animating mission of the legal subgroup guiding us in 2015:
Develop recommendations about resource owner-and-requesting party [Alice-and-Bob], resource server-and-authorization server [service-and-hub], and any other transactional relationships in the UMA environment, keeping in mind international jurisdictional friendliness; applicability to many different vertical and horizontal use cases, including health; and support of higher-level access federation trust frameworks and similar efforts.
The sharpened mission particulars guiding us 2016:
- Drafting model text (the term and abbreviation definitions and the model clauses)
- Gathering requirements for the environment for using the model text
- Being guinea pigs for the environment
Target Q1 for external beta review of the model text. "Accordion" the environment requirements to account for budgetary uncertainty.
Update August 2016: We have made some progress on the model text, but it has turned out to be important to work on an auxiliary deliverable, a primer called UMA in Contractual and Regulatory Contexts, that maps the relationships of concepts at the technical, contractual, and regulatory levels. Expect more progress in coming months!
The subgroup's meeting times and notes are here. We meet on Fridays at 8am PT.
If you are just visiting and are interested to join the UMA Work Group and take part in this subgroup's efforts, we invite you to join! Visit our home page and see the Join link there. Note: Since the legal subgroup meetings do not count towards WG quorum, it's advised to join as a "non-voting participant" unless you also intend to join the WG meetings on Thursdays at 9am PT.
Sources of liability tension
These are some key trust relationships we are exploring for the "liability tensions" within them, that is, the misalignment of incentives that leads to a reluctance to deal with each other, mistrust, or added friction in decisions to use or deploy UMA. Here are some of our use cases?
- When Alice sets up criteria for access to a digital data resource of hers, such as "Only Bob can access this", can she ensure that the other actors in the authorization chain are doing their best to make sure Bob "is who he says he is" by the time he (someone) actually gets access?
- If Alice wants to impose limitations on how Bob uses her stuff using business-legal methods vs. some kind of (say) encryption or DRM methods, such as "Bob must promise not to share this data with third parties", how can she ensure these limitations stand up?
- Can the host of some sensitive information of Alice's, such as personal data, trust an authorization service that promises to do the job of protecting that information in an outsourced fashion? This is roughly akin to the challenges of federated authentication, only for authorization.
- Can Alice trust an authorization service to do as she bids when it comes to protecting her stuff, if she didn't personally hand-code it?
- Can an authorization service rely on the hosts of Alice's data and the client applications that Bob uses to operate correctly in their UMA roles?
- Can the host of Alice's data ensure that it can keep out of legal trouble even if Alice's authorization service appears to want it to share data with a recipient who is in a jurisdiction to which personal data is not allowed to be sent?
The model text work is being encoded in the CommonAccord.org system. CommonAccord is:
"...an initiative to create global codes of legal transacting by codifying and automating legal documents, including contracts, permits, organizational documents, and consents. We anticipate that there will be codes for each jurisdiction, in each language. For international dealings and coordination, there will be at least one "global" code."
Here is the draft model text. Only the definitions have been worked on as of 1 April 2016. It helps to know how to navigate CommonAccord text: First, click on 0.md to get the current full text, and the "Document" link to expand the Source view into a proper document.
