# 2023-03-16 Working group periodic update

### Agenda
- Access token request
- templating
- filtering

### Access token request

Currently RFC014 had a line in §4.2:

_The credential issuer equals the sub field of the JWT in the access token request._

This will probably have to change to _the issuer must be trusted for the use-case_?

### Templating

Because VCs ar not directly constructed but are to be constructed in response to _events_ we'll need some sort of templating to create the right VCs. This has to be coordinated with efforts on implementing OIDC4VCI.

### Filtering

To select the right _events_ for VC generation, some sort of filtering language would be required. [DIF presentation exchange](https://identity.foundation/presentation-exchange/) seems the right candidate.
