Working Group Updates

Concepts and Terminology Working Group

Terminology Engine V2 (TEv2)

  • We are making steady progress on TEv2 but it is not finished yet
  • TEv2 will enable any terms communities (e.g., ToIP WGs or TFs) to generate a glossary from one or more terms wikis
  • It will also automate hyperlinking terms within a specification, white paper, or other deliverable to their glossary definitions
  • Several TSWG TFs are planning to use TEv2 to publish the terminology for their specifications and papers

Developing New Mental Models

  • Mental models explain how a set of concepts are related within a specific domain—a “mini-ontology”
  • They are usually documented both in writing and in UML diagrams
  • They add much greater depth and cross-conceptual understanding than glossaries alone
  • Co-chair Rieks Joosten of TNO is leading the work on developing several foundational new mental models

Meeting Times - CTWG

Now Making Extensive Use of Github Discussions

  • As our Task Forces are having deeper discussions and doing more asynchronous work, we are relying more on Github Discussions
  • This is a very easy-to-use feature than can be turned on for any ToIP GitHub repo (you just need a free GitHub account)
  • If you can use Google docs, you can use Github Discussions — see this excellent tutorial:
  • Join these discussions to see it at work:

Meeting Time -TSWG

  • The Governance Architecture TF, created Gov Arch Methodology draft (incl. Outline deliverables, Governance Requirements, Arch Structure). Partitioning Operations from Governance. Use cases. Draft Mental Model
  • The GSWG “Museum Pass” -> “Attraction Pass” (broader topic). This is coordinating with the DIF Hospitality & Travel SIG. Current “AtPass” focus is Use Cases illustrating Governance and other specific ToIP WG/TF issues;
  • The Issuer Requirements TF - focus is on requirements related to the issuance (1st), plus it’s role on interacting with Holders, Verifiers and interop of VCs. Highlighting what are tech/governance vs. human issues/requirements (cross jurisdiction (interop), criteria for trust, …) and how tech/gov can support human trust decisions. (lively discussions)

Utility Foundry Working Group

Ongoing work items (Unchanged since the last report):

Public Utility Directory:

  • This is a list of all the active Layer 1 utilities which currently have representative members at ToIP
  • Looking forward to including the Candy network if they are interested in being part of this chart.

A Framework for Evaluating Layer 1 Utilities - Overview

  • This document identifies the key differences and considerations between the core Layer 1 utilities for clients/customers looking to adopt a ToIP compatible SSI solution
  • Final review is complete - formatting and delivery to TSC remains.

New/Future work items

  • We are currently contributing all of our ongoing efforts to the Governance Architecture Task Force.
  • Will resume with UFWG items when that effort scales back.

Meeting Time - UFWG

The UFWG is currently contributing all of its efforts to the GATF so meetings are currently suspended. UFWG meetings will resume when that work is complete.

Ecosystem Foundry Working Group

Goal is to gather ‘real world’ feedback, perspectives and insights from future trust-tech adopters at the business/organizational level

  • Initiated survey

Working on analyzing results (84 responses)

Challenge - results still very tight within the community

  • Currently analysing survey results to formulate into shareable story

Join the EFWG and let us know if you would like to contribute to this

Ecosystem Components

  • We’re moving at a snail’s pace to develop and present “Digital Trust Ecosystem Components” for review and feedback by the ToIP Community, before developing Learning Pathways based on those components.
  • But we’re getting there!
