scope of the use cases - focus on the interactions of the Primary Actor in their journey to fulfil the business requirement
Peter: the actual business requirement (of the venue) for Communicate a Credential Presentation is actually "Obtain proof of age to fulfill regulatory obligations"
Tom: There are actually a set of Purposes that are the focal point for the Business Requirement
Andrew: we should look at each actor in the role of Primary Actor - because each Actor could have different desired actions - that might not appear if looking at steps from certain other actors' point of view
Christopher: Holders will never read these specifications - only developers/providers/organization - because they must implement something
PEMC shall use this convention: Use Cases describe the steps taken by Actors. Actors can only be Humans.Â
e.g. the Reader software designer must fulfil requirements of their Primary Actor - the operator of the Reader software. The operator of Reader software has business (and technical) requirements that are determined by that operator's Stakeholders e.g. regulatory, statutory, business customs, usability obligations and stakeholders (reminder: an Actor is a special type of Stakeholder that interacts with the System). Note: the stakeholder interests and operator's requirements must be run through the "privacy enhancing" lens - and maybe this influences the privacy defaultsÂ
Christopher: there is no guidance within 18013-5 to Reader developers about what to do if the Presentation does not return a specific piece of information e.g. date of birth AND Age_over_nn. There are 18013-5 requirements for what the Holder's application must do. ie the Holder's application behaves in Privacy Enhancing ways - but nothing for Reader developers on how to develop Reader software in a Privacy Enhancing way. Same concerns apply to the developer of Issuer software - guidance about how to build the system in a Privacy Enhancing way.
Tom: note that concrete use cases are more like the 'harmonization of the rules' material from Tom
John: task assignments for the initial drafts for Abstract Use cases
Loffie to create an initial draft for Issuance
Gail: PEMC needs to ensure alignment with AAMVA implementation guidance & Future Identity Council guidance
Christopher: raises concerns about scope of user stories - ensure that PEMC remains focused on digital/mobile credentials - stay away from the other topics that are not related
