          Azure Pipelines
  • Ursa doesn't have any CI
  • Decided: Move forward with GitHub Actions
• Rich Schemas:
  • Need to correct existing HIPEs
  • Need to evolve DIF DIDComm to support Rich Schemas
  • Implement first in Indy-VDR and Indy-Credx, then decide how to migrate there from LibIndy.
  • How will we mix old credential definitions with new credential definitions?
    • Only difference is the mapping object
    • Anoncreds 1.0 vs 2.0 might require more effort to remain compatible. Anoncreds 2.0 only support Rich Schemas (new credential definition object)?
