The Inputs and Semantics Working Group is no longer being actively updated as of Sep 1, 2022. This WG will remain as an archive for the documents, meeting minutes, etc.

The replacement - for Data topics for Trust Over IP - is the Data Modelling and Representation Working Group (DMRWG)  (TODO needs link)

This is also true of the following Task Forces (as captured under the I&SWG) and their existing meeting schedules 

  • Privacy & Risk TF
    • Future Topics to be split between the Governance Stack WG (GSWG) and DMRWG 
  • Storage & Portability TF
    • Future Topics to be split between the Governance Stack WG (GSWG) and DMRWG
  • Notice & Consent TF
    • Future Topics to be split between the Governance Stack WG (GSWG) and DMRWG


The Inputs and Semantics Working Group (ISWG) supports a practical approach to further enable the adoption of the Trust over IP dual-stack architecture by bringing a balanced view of decentralized network paradigms to the overall mission of Internet-scale digital trust. All data inputs operated on by any process or system must be authentic with deterministic semantic objects providing meaning and context at the time of capture.

The mission of the ISWG is to define a decentralized key management infrastructure (Inputs domain) and data capture architecture (Semantic domain) for Internet-scale deployment. The scope of the ISWG is to define specifications and best practices that bring cohesion to data entry (aka Inputs) and data capture (aka Semantic) processes and standards throughout the ToIP stack whether these standards are hosted at the Linux Foundation or external to it. Other working group activities will include creating template Requests for Proposal (RFPs) and additional guidance to utility and service providers regarding implementations in that capacity. This WG will be divided into Inputs and Semantic domain groups and will organize Task Forces and Focus Groups to escalate the development of certain components if deemed appropriate by the majority of the WG members and in line with the overall mission of the ToIP Foundation.

The ISWG-S meets weekly on a Tuesday from 09:00-10:00 US PT / 17:00-18:00 UTC
