Notes

1. Welcome and Linux Foundation antitrust policy

2. QR Codes & URLs

  • Decision that QR code will not support URL (concerns over phone home)
  • If you want to secure data, you can (we are not going to say you can’t) but we’re not going to support a URL that points to the data online; could add this as a “may” but can’t require it 
  • At end of day, let’s not try to solve an unsolvable problem with paper now - hopefully by the time zero knowledge proofs stabilize, people will have gotten off paper  

3. Draft Discussion

  • Recommendations on serialization of data will be useful
  • Get JSON payloads (two letter codes for everything)
  • W3C vocabulary - MATTR seems open to harmonizing things?
    • MATTR should look at what is being pulled together and should give feedback on
    • Include data chairs and Kaliya in outreach to MATTR
  • EU is doing a validation of the URI
  • Passes are not long term
  • Paper credentials cannot be bound to an electronic device
  • Don't want to build a hardcoded business model into implementation - we don’t want to get into that business; allow someone to verify an implementation
