Hey All,

I mentioned on the CCG Call today, there is a new DIF Work Item regarding
wallet interoperability testing of verifiable presentation exchange:

https://github.com/decentralized-identity/waci-presentation-exchange

This work came from multiple successful IIW sessions focused on a community
vision for achieving wallet interoperability for verifiable presentations.

Special thanks to Kaliya for leading the sessions and to Sam and Drummond
for their help on supporting an integration path for BBS+ with Good Health
Pass and the VC HTTP API Vaccination test suite and vocabulary.

And most importantly, thanks to the folks at Bloom for writing the original
WACI spec:

https://specs.bloom.co/wallet-and-credential-interactions/

It's awesome to see the community aligning around support for a shared data
model (W3C VC Data Model), now all we need is at least one way to exchange
VPs over HTTP.

It's also worth mentioning that the OIDC is working on their own version of
these APIs as well:

https://bitbucket.org/openid/connect/issues/1212/siop-chooser

Major motivation for separating the "Traceability Ecosystem Guide" or
"Traceability API" was to allow for a more inclusive approach to these
other communities, including direct support for OIDC and addressing
concerns regarding authorization.

As a member of both DIF and CCG I am committed to keeping them as aligned
as possible and look forward to working with folks like Tom and Kristina or
aligning with OIDF as it evolves its support for presentation exchange and
wallets.

* keeps running at the speed of the broader community *
