VC Evidence Discussion

Hello all,

I’m seeking some input on VC evidence. This is a topic relevant for VC-EDU because education data specifications like Open Badges and CLR may contain an evidence property to support the achievement. This evidence could be a test score, a link to an image, video, and/or web page, etc. that demonstrates competency or participation. These specs are working towards aligning with VCs and it was originally thought that this type of evidence would be included as part of the credentialSubject if it existed.

This would look something like this:

https://json.link/21SpTf0rC4 <https://json.link/21SpTf0rC4>

But since VCs already have an evidence property that allows for an array of evidence, it seems to make sense to use that property instead of using a separate property like the one demonstrated above. The rationalization is that VC evidence could be an array that supports what is needed for a credentialSubject to offer to support the verifiability of a VC such as a student id or it could also support the achievement that is being claimed as discussed above. This would look more like:

https://json.link/0gqe5D1U4K <https://json.link/0gqe5D1U4K>

Can you share your thoughts on this second approach? Do you think the VC.evidence support the achievement evidence too? 

Thanks!

Kerri
