Agenda

• Announcements
  
  • Publishing requirements for data signatures inside XBRL and inclusion of ACDC Data Attestations.
    • Technical working group next step
  • Roots ID 6 month effort with Cardarno Foundation (supply chain, KERI, ACDC)
    • EGF Working group as a suggestion to get started with supply chain governance
  • Looking to get examples for CESR, for parsing events  
    • Creating events and KELS to start
  • ToIP TSWG Trust spanning layer task force continuing meetings, looking to adopt KERI (ACDC)

Reports implementation of ACDCs

• vLEI
  • work items to update schema
  • RootsID vLEI from Provenant
    
    • Legal Entity vLEI and Offical Organization Role vLEI credentials for Rodolfo and Lance et al
• ViRA
  • See above on the XBRL
• HCF
• Provenant upcoming announcements
  • MWC conference on Mobile World Congress
• RootsID
• QUI Identity
  • KERI first then ACDC

Discussion Items

• W3C Face to Face outcomes
  • Scope to try resolve @context issues present within the W3C VC DM (multiple lengthy github issues)
    • ACDC can become a verifiable proof (external) with a uni-directional transform to the base media type of credential+ld+json 
      • https://weboftrust.github.io/vc-acdc/
      • Hopefully approved by March feature freeze of the w3c vc data model
        • Requires three sponsors (GLEIF, ProSapien, one more)
        • Additional sponser (Shawn)
    • Similar approach from w3c/vc-jwt (https://github.com/w3c/vc-jwt)
    • Help appreciated with review/comments/questions
    • uni vs bi directional
      • receiver can process an ACDC, transform produces a valid JSON-LD object that can be used for RDF
      • vc-acdc will be unidirectional
        • default @context is open to discussion
      • more complex example would be a vLEI transformation
      • vc dm is payload of an acdc
      • Issue for addition of payload  in ACDC up for discussion (https://github.com/trustoverip/tswg-acdc-specification/issues/74)
    • embedded proof follow similar pattern to how SAIDs work
      • adding proof inside the vc
    • external proof act as a container for the vc, the container contains the proof (Proof is on the ACDC)
  • Also presentations on VC Data Integrity Proofs and Holder Binding
