MOTION: Approve minutes of UMA telecon 2018-02-15: APPROVED.

Charter updating

The "Avoid (defining) cryptography" and "Permit digital signatures" design principles are sort of in tension. There's also an interaction with the "Avoid complexity" DP. What do we mean? UMA wants to be agnostic for the reason of adoptability, but there's a security consideration here so that "the fox doesn't run the henhouse". Maybe another way to state the "Permit..." DP is: "Permit (don't preclude) the use of cryptographic techniques that enable strong security and privacy properties". Most of our DPs have guided us pretty well over the years. But this last one seems like an exception, at least as stated. There are a lot of other security use cases we wouldn't want to preclude/would want to enable; Domenico mentions data integrity, for example. OTOH, originally it was meant as a kind of reciprocal to ensure that third parties could use digital signatures and encryption if they want to. Maybe we don't need the reciprocal.

MOTION: Andi moves: Accept the charter refresh proposal. APPROVED by unanimous consent.

AI: Eve: Get the approved charter refresh text into the online charter.

AI: Eve: Edit the Requirements document to indicate that the new charter has the most current version of our DPs and requirements.

WG Legal Adviser role

Do we need this role? It has potential benefits in helping us find liaison relationships, goes the theory. A "Legal Editor" role name is more in line with other roles we have on our leadership team.

MOTION: Andi proposes for Tim Reiniger to serve in the Legal Editor role on the UMA WG Leadership Team for an annual term. APPROVED by unanimous consent.

Next meeting

Mike proposes that we discuss an extension for scope expressions. Eve asks that he propose a formal extension in order for us to discuss it productively.

If anyone has extension ideas they'd like us to discuss, please do the same!
