Recommendation of QR #255

Open nissimsan opened 1 year ago

nissimsan commented 1 year ago

I'm looking with interest at https://github.com/Open-Attestation/open-attestation/tree/master/benchmarks/qr-code

How are you guys dealing with trade documents beyond the maximum 34 parameter limit? I suppose the only choice it to revert to online by-reference? If that's your recommendation, is this documented anywhere so we can follow your best practices?

Do you see a "graceful degradation" kind of approach, where issuers encode by value up to the parameter limit, and then encode by reference for larger documents? Curious about your thoughts on this...

Hi @nissimsan, yes we are implementing via an online hosted solution (e.g. storage bucket) due to the size limitations of QR codes.

You may find a brief explanation documented under the Universal Actions section. Essentially, the hosted URL of the document is provided as a query parameter to the verifier.

We have also listed out a few distribution methods along with their pros & cons.
