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 

Action Items

1. David to reconcile section 1 and section 6 
2. Vitor to add one-way and two-way credentials to glossary
3. Change bullets to numbers
