Thank you, This is very useful information. I brought up consent receipt in the call because I am wondering whether it is possible to enhance offer-negotiate-accept terms-record flow for consent receipts. Namely, I’ve been thinking about whether consent receipt can act as a seed for creating a user policy and/or machine readable license which may be used to authorise future interactions of the user with the same service (which may be used by UMA AS).

Also, there are many variations around offer-negotiate-accept terms - for user-centric and VRM-type flows, the first offer might be from the person rather than from the vendor. And so on. The Personal Data Receipt (a.k.a. "Consent Receipt") arises at f). 'Vendors' keep records of agreements and interactions for operational and potentially regulatory reasons. Individuals are never offered a 'receipt' unless the interaction is a sales transaction (and even then, not always). The Personal Data Receipt is intended to be the person-side record that, once enough are accumulated in the person's vault/wallet, can be analyzed in the same way that Quicken or Mint analyses and manages financial statements and receipts. An imperfect flow diagram of the above is here: https://share.mindmanager.com/#publish/NEsOqlqyWZ2buLfRgPdytSBf9KO1pQpZZMM4J... with more text here: https://kantarainitiative.org/confluence/display/infosharing/Product+Roadmap... On first glance, the "machine readable licence" shows up in c), d) and f). The specific form of the license is secondary to my mind - as long as it identifies the parties, describes the terms, describes the restrictions, and is tamper-evident - there are a few other properties... So the 'consent receipt' is definitely not the same thing as the 'machine readable license' - but they probably occupy the same place in the 'agreement flow concept'. CIS WG is creating v2 of the receipt spec - and it will be a generalized data receipt. It should be possible to create some kind of profile of the eventual v2 that accommodates the UMA license use case (or not - we can discuss) andrew.
