This the home page for a draft drafting of the the ToIP Technology Architecture Specification (TAS), a Draft Deliverable deliverable of the TSWG developed by the Technology Architecture Task Force. After the publication of the first public review draft of the TAS V1.0 December 2022, the ToIP Foundation also established a home page for the TAS on the ToIP website. It also established a page for a living document about the ToIP stack development process called Evolution of the ToIP Stack. 

Links

Work on the TAS began in Google docs but has now moved primarily to the TATF GitHub repository. Following are links to all the current sources:

• TAS GitHub Markdown version
• TAS GitHub Issues
• TAS GitHub Discussions
• TAS Source Diagrams (Google Slides) <== SOURCE DIAGRAMS used in the TAS
• ToIP Protocol Stack Diagrams (Google Slides) <== All of all our past diagrams (some of which have been copied to TAS Source Diagrams)
• TAS WORKING DRAFT 03 Google doc version <== REFERENCE ONLY — NO LONGER ACTIVE
• TAS OLD WORKING DRAFT 02 Google Doc version <== REFERENCE ONLY — NO LONGER ACTIVE
• Evolution of the ToIP Stack <== NEW proposed companion document
• TATF Google Drive Folder <== WHERE ALL OF THE ABOVE may be found

To comply with the intellectual property rights protections in the charter of the ToIP Foundation (as required by all Joint Development Foundation projects hosted the Linux Foundation), all contributors MUST be current members of the ToIP Foundation. See the official list of contributors in the Working Draft.

Terminology

In this document, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL", when appearing in ALL CAPITALS, are to be interpreted as described in RFC 2119.

All other terms in bold will be defined in one or more of the ToIP glossaries in a process being defined by the ToIP Concepts and Terminology Working Group.

Purpose

The purpose of this specification is to define the overall architectural requirements for each of the four layers of the ToIP stack and how they are abstracted from the layer below. This specification will lay the overarching foundation for component specifications — developed both inside and outside the ToIP Foundation — that will specify more detailed interoperability requirements such as specific protocols and interfaces. The starting point for this TF will be the original Hyperledger RFC defining the ToIP stack, however significant evolution is anticipated based on the Design Principles for the ToIP Stack. Note: this specification is intended to serve as a direct a counterpart to the ToIP Governance Architecture Specification deliverable from the GSWG Governance Architecture TFcurrent draft.
