UMA Legal

You can find a description of the overall User-Managed Access proposition here:

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.


*"enable a resource owner to control the authorization of data sharing and other protected-resource access made between online services on the owner’s behalf or with the owner’s authorization by an autonomous requesting party"

Subgroup meetings

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?

Work to date on model text

The model text work is being encoded in the system. CommonAccord is:

" 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. The definitions are more mature than the clauses. It helps to know how to navigate CommonAccord text: First, click on to get the current full text, and the "Document" link to expand the Source view into a proper document.

Additional artifacts

An UMA in Contractual and Regulatory Contexts primer/manual is in draft form. This slide deck, presented at Digital Contracts, Identities, and Blockchain at MIT in May 2016, shares some key use cases. A few additional artifacts are available on the WG's GitHub wiki.
