Re: DIF Proof of Age workshop (webinar)

*Hi Manu,*

Thanks for raising this. We socialized this initiative at IIW this past
fall.  We presented an initial schema standardization effort for Age
Verification and Estimation. The discussion centered around the development
of a general purpose age schema which would allow for both “age estimation”
(several assurance methods to be used) as well as “age verification”. I
presented an early draft of the data fields being considered for the schema
spec. The group provided feedback regarding the fields and also suggested
additional ones to be considered.

One of the participants pointed me out to existing solutions for age
verification in the industry, including https://www.mytruage.org as well as
the support of age verification included in the credit card payment
networks (EMV). My understanding is that "My True Age" is following the
Connexus spec. We are open to discussing how to better collaborate with
Connexus / NAC. That website you shared indicates that the main overlap is
on the Age Token credential (
https://convenience-org.github.io/age-vocab/#OverAgeTokenCredential ).

From my analysis the age token credential is actually a subset of our
"Proof of Age" schema. The only field that overlaps is the "overAge" field.
The schema itself is being used by Privado ID / Iden3 in the web3 space for
platforms that want to age-gate adult content (I am involved in some of
these discussions currently).

We would be open to discussing this with Connexus so that their Age Token
credential aligns well with our more general Proof of Age schema proposal.
Do you think we could propose a meeting to explore collaboration?
