2019-09-11-A Aries Working Group Call (US morning)
Summary:
- The right place to create an Anoncreds library: shared libraries export C-callable API, but the language doesn't matter (C, Rust, Go)
- Aries-Framework-Go has a Verifiable Credential package that could be made available to other frameworks
Building a generic DIDDoc parser
- Aries-Wallet is probably the right shared library to build first
Note: This call is Recorded. Recordings posted at the bottom of the page.

RFC Progress
Other Business
- Aries shared libraries export their API as C-callable, but the implementation language doesn't matter: C, Rust, Go
- DIDDoc parser in Rust:
- What is the next step we can take:
- Richard's proposal for order of work
- Move Indy-SDK into Aries-Core (October release)
- Split out wallet into Aries-Wallet (November release)
- Define the resolver interface (November effort)
- Split out resolver into Indy-Resolver (December release)
- Questions
- Iterative approach: do something that we can improve on.
- Start with the needs of the agents (Aries-Cloud-Agent) and build the Aries core architecture from that.
- Maintain Indy-SDK alongside Aries-Core / Aries-Wallet / Aries-Resolver?
- Who will be the maintainers of the new libraries? Do we want cross-organization PR reviews?
- Best way to maintain history, and make the reorg transparent
- History continues public in Indy-SDK, so might be better to start clean in Aries
- concerns with old DCO process: can use Mike Lodder's approach he used for moving indy-crypto to ursa
- What to do with the Indy CLI?
- CI / CD in Jenkins or GitLab?
- Iterative approach: do something that we can improve on.
- Daniel's proposal for order of work
- Split out Indy wallet into Aries-Wallet
- Define the resolver interface and create the resolver libraries (indy and peer)
- The peer DID resolver isn't dependent on other libraries https://github.com/dhh1128/pypeerdid
- Wait on Aries-Core
- Richard's proposal for order of work
- Architecture of Aries core library
- What is our fastest path to a library that framework implementors could consider using?
