Scheduling future meetings
January 1: Cancelled
January 15: Need to select a topic
Aries language wrappers
Connect-a-thon proposal: let's only build Frameworks instead of SDKs—let's be opinionated! Simplify the experience of a new developer.
Merge the SDK and the Framework repositories so developers don't have to choose between them.
aries-sdk-go should merge into aries-framework-go
aries-sdk-javascript should move into aries-framework-javascript
other SDKs renamed as Frameworks?
Can have a separate SDK artifact in the Framework repository, if desired.
When can we deprecate the Indy SDK wrappers?
Overlap in development between Indy and Aries. New developers should start in Aries.
Hard to maintain CI / CD and do bug fixes for environments and wrappers we don't use.
IS-1423 for DotNet, because the Aries Framework is mature.
IS-1424 for Java, JavaScript, Android, iOS
Challenges with Python
Misalignment between RFC 0094 and ACA-Py
ACA-Py pull request: https://github.com/hyperledger/aries-cloudagent-python/pull/240
Evernym products and Pico implemented one way, ACA-Py and DotNetFramework implemented the other. Resolution will be a breaking change.
A breaking change will be needed in the near future to implement Tobias' proposed changes to the envelope format.
Future Topics
Next call
Other:
Aries KMS design
Define approved algorithms
Define plugin interface
3rd party libraries we could leverage:
Google Tink as an encryption library
Tobias' proposal for evolving DIDComm
