Sphereon as part of its Vindicatio project brings the new DIF Presentation Exchange to DIF/W3C SSI solutions compatible with Aries Present Proof Protocol v2 using a layered approach to achieve both integration and interoperability.
The REST Api and state machine can run in Docker and exposes the functionality to other programming languages for a more direct integration. Then there is a stateful bridge that integrates DIDComm v2 and CHAPI (and future OpenID-Connect). The bridge will be similar to Aries Present Proof v2 and integrate with it and in the future support a backend like Verity or similar as well. This means parties can talk using Presentation Exchange compatible datastructures, across different transports and with different products.
