Hi All,

Below is what we discussed in the DCP WG today as the list of things we
want to work on after HAIP 1.0. *Also as an inspiration for the sessions
during IIW and DCP WG on Friday.*

   1. Both VP and VCI: HPKE
      1. Waiting for a draft on vanilla hpke (Gareth/Lee)
      2. Waiting for Montreal IETF in 3 weeks on IETF jose-hpke draft
      updates
      3. https://github.com/openid/OpenID4VP/issues/310
   2. VCI: Interactive Authorization Endpoint (IAE) - presentation during
   issuance
      1. Seven PRs open in VCI repo
      2.
      https://github.com/openid/OpenID4VCI/pulls?q=is%3Apr+is%3Aopen+label%3Aiae
   3. VCI: Server-to-server issuance
      1. Urgent, but bigger item to define
      2. Let’s start with the list of requirements
      3. https://github.com/openid/OpenID4VCI/issues/663
   4. VCI: DC API
      1. There was a PR by Lee that was closed
      2. Useful for credential offer
      3. https://github.com/openid/OpenID4VCI/pull/476
   5. VCI: credential usage policy
      1. https://github.com/openid/OpenID4VC-HAIP/issues/260
   6. VCI: per-credential metadata
      1. There is a proposal already
      2. https://github.com/openid/OpenID4VCI/issues/421
   7. VP: Discovery of public key / certificates of Verifier by Wallet
      1. https://github.com/openid/OpenID4VP/issues/671
   8. VP: purpose/intent_to_retain default behavior
      1. https://github.com/openid/OpenID4VP/issues/669

The order is not the priority. WG still needs to agree on the
prioritization.

Thank you!
Kristina
