Bakery for OBv3

[kayaelle]

Does anyone know of open-source software or a hosted software that can un-bake an OBv3? I have a colleague who has downloaded her OBv3 badge from Credly and I'm guessing that it is a baked png. We'd like to view the source and see if it can be added to the LCW.

Thanks!

Trying this: https://pypi.org/project/openbadges-bakery/

and https://www.npmjs.com/package/openbadges-bakery-v3

I'm not aware of any open source tool that directly extracts OBv3. I personally use https://www.npmjs.com/package/png-itxt for PNG baked OBv3. It's a command line utility, though

Hi @kayaelle, I've also used https://www.nayuki.io/page/png-file-chunk-inspector

But if you need help otherwise on the Credly implementation please feel free to reach out to me at [email protected].

During our implementation of OB 3.0 download I did attempt to import a badge (after pulling out the JSON-LD) into LCW, see here:

Thanks, @xaviaracil & @ahripak! I found an online one to test with and got the same results as Alex. DCC will add eddsa-rdfc-2022 capabilities to LCW and VerifierPlus. The png extractor libraries are a good holdover but we should also investigate unbaking svgs. I believe the old Mozilla bakery did accommodate svg but not positive.

@ahripak - ideally, a badge could be shared to a wallet without baking. It would make it a lot easier for the users. I'll reach out to you to explore. Thanks!
