Reliza just announced ReARM support for Transparency Exchange API (TEA) Beta 1. Read details here. I believe this is world first implementation.
This is a big milestone for me as I was involved in TEA creation for the past year almost since its inception. The TEA is an effort to create common approach of how we share metadata. This would eventually apply to both software and hardware as well as vulnerability details.
The standard itself is by no means complete but what we have right now is a good first step.
We have TEA implementation enabled on ReARM Demo currently and we are sharing TEA-related data there under permissive licensing to help with other implementations and ideally to try to establish integrations between them. That is because next big thing I see here is demonstration of cross-system integration based on the TEA standard.
