This the home page for a draft of the ToIP Technical drafting of the ToIP Technology Architecture Specification (TAS), a proposed Draft Deliverable deliverable of the TSWG developed by the Technical the Technology Architecture Task Force. The Working Draft of this specification will proceed through three stages:

...

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== REFERENCE ONLY — NO LONGER ACTIVE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== REFERENCE ONLY — NO LONGER ACTIVE
• TATF Google Drive Folder <== WHERE ALL OF THE ABOVE may be found

Contributors

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 to this Pre-Draft Deliverable MUST be current members of the ToIP Foundation. The following contributors each certify that they meet this requirement:

• Darrell O'Donnell, Continuum Loop
• Drummond Reed, Evernym
• Wenjing Chu , Futurewei
• Tim Bouma, Individual
• <add your name here>

Other contributors MUST also add their name and membership affiliation to the Google doc or wiki page version of the spec as it proceeds through development.

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 four more future ToIP specifications—one for each layer of the stack—that will specify detailed interoperability requirements for each layer. This TF will be specifically focused on adapting the original Hyperledger RFC defining the ToIP stack while at the same time reflecting lessons learned from the development of 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 TF.

Deliverables

The deliverable of this Task Force is the ToIP Technical Architecture Specification—a specification of the overall architectural requirements for each of the four layers of the ToIP stack and how they are abstracted from the layer below. It is anticipated that this specification will lay the overarching foundation for four more future ToIP specifications—one for each layer of the stack—that will specify detailed interoperability requirements for each layer.

Motivations

For complete background on the motivations for development of the ToIP stack and why it consists of two halves—the ToIP Technology Stack and ToIP Governance Stack—please see the following documents:

• The original Hyperledger RFC defining the ToIP stack.
• The Introduction to ToIP white paper (original version; draft second-generation version)
• Design Principles for the ToIP Stack (draft version)

PLACEHOLDER for Working Draft Specification 

Once the Google doc version of the specification is sufficiently complete, the specification will move here for final review.
