Examples and recommendations of usage

[naftis]

Hi, we're looking into issuing verifiable credentials within @opencrvs. We are an established open-source civil registration platform that records life events. We're both piloting and being deployed in production in various countries.

My task is to investigate what is the best approach for implementing OpenID4VCI for birth certificates. This repo is fairly low level and doesn't have much documentation yet, so I'm wondering

1. if you'd have a view whether we could implement using your abstractions, and whether you have suggestions for other platforms or abstractions for us, and..
2. if you have any implementation examples or code snippets of issuance

Also just after writing this I noticed this is a part of https://github.com/openwallet-foundation/credo-ts which I'll look into as well (and probably should've opened this discussion there)

Our functional flow is still getting together, but in general:

1. registrar fill out the birth registration form
2. registrar registers the birth, and prints birth certificate to the mother (/ any informant)
3. registrar shows an QR credential offer to the mother
4. mother scans the credential to herself

Thanks for any inputs

Hi @naftis,

This library is indeed quite low level, it's meant to be integrated into a framework or if you require a lot of control over all aspects of the issuance and verification flow.

We are using it in the Credo framework (which you also linked), which provides a much more high level API for issuance and verification. Settings up a flow like you described should be quite straightforward with Credo. If you're just starting to build I'd recommend installing the latest Credo 0.6.x alpha, which is almost ready to be released, and is fully up to date with the latest OpenID4VC features.

You can see a simple CLI demo in the credo-ts repo: https://github.com/openwallet-foundation/credo-ts/tree/main/demo-openid

We also have a playground, but note that this contains a lot of features to showcase the capabilities which you probably don't need based on your functional flow: https://funke.animo.id (https://github.com/animo/openid4vc-playground-funke). This works with e.g. our Paradym Wallet which you can install in the app/play store (and is also open source: https://github.com/animo/paradym-wallet)
