Introduction
The Technology Stack Working Group (TSWG) specifies requirements, specifications, and test suites for the technical architecture of the ToIP stack. For an overview of the ToIP stack, see the Introduction to ToIP white paper. For an overview of the ToIP stack development process, see the Evolution of the ToIP Stack.
Scope
The scope of the Technical Stack Working Group (as defined by our charter revised in September 2023) is to define (directly or by reference) the technical standards, test suites, and interoperability certification standards for the Trust over IP architecture stack as described in the Introduction to ToIP paper and the Design Principles for the ToIP Stack paper.
