We've collected a series of issues at the nexus of #trust, #ROctrl ("RO can meaningfully throttle access that RS gives"), and #ROctrl ("RS can throttle access beyond AS-imposed limits"), and "consent and notice and information sharing matters" that we have nicknamed shoebox thanks to Andrew Hughes. Here are the relevant issues; you can see some of them go way back in time!

246: Endpoint for collection of "receipts" and notifications of RS action in case of extraordinary behavior
245: Location Constraints
224: RS Notifies AS or RO of Access
63: Audit logs to support legal enforceability
24: Possible to audit host's compliance in giving access based on a legitimate active permission from the AM?

These issues variously detail use cases in the UMA context. This mega-issue is connected to various other efforts, including our own UMA Legal subgroup (see particularly these notes), the Consent and Information Sharing WG's Consent Receipt work (note that the CR spec has just gone out for Public Review on Jan 6), FHIR (for its "Consent" structure), and possibly others.

Consent records and transaction records and signed notifications of exceptions, etc., are usually conceived of as being useful to store in a secure transaction repository of some kind. Some questions:

Given that UMA isn't alone in this, should we even be talking about UMA-specific functionality? Are we talking about an AS hosting a "shoebox endpoint" because an AS is the right place for such a thing to be hosted, or because a server that happens to be an AS is also a "shoebox endpoint server" (or something like that)? What is UMA's differential interest? Has anyone in other groups proposed something concrete around a "shoebox endpoint"?
There are people working on putting consent/transaction receipts on blockchains. ("Drink!") Should we be working on centralized places to store notifications/records?
UMA Legal has figured out what it wants to do, to a point, in the legally enforceable world. How machine-readable can the proposition get -- at least for our purposes in UMA2?

Please feel free to add your own questions (or answers)...
