We see the connection.
We are I2IDL.
Seeing things Eye to Eye
be a part of the story.
The Institute for Infrastructure and Interoperable Data in Learning (I2IDL) is an independent, non-governmental, non-profit organization advancing the science of open source data systems serving learning, training, and education organizations across the globe.
We maintain and operate essential open source systems required for global learning data interoperability research and we serve as a hub for research and innovation in learning and training technologies.
Especially in regard to artificial intelligence, the power of data interoperability is in the ability to increase transparency, verifiability, and accessibility.
We invite you to join us as we explore new opportunities for innovation and accessibility in learning data and open source systems built to support better outcomes.

Ensuring Learning and Training Data Infrastructure and Interoperability Research Beyond ADL [access]
Why I2IDL?
Interoperable data architecture depends on operational conformance testing and the resources that stakeholders need to ensure best practices.
Since 2017, the IEEE Learning Technology Standards Committee (LTSC) has been developing global data standards that support the Total Learning Architecture (TLA) — an approach to standards-based learning ecosystems that was designed and shepherded by the Advanced Distributed Learning Initiative.
I2IDL was established in late 2025 to ensure a non-governmental non-profit third-party organization could sustain to ensure the maintenance of the open source TLA resources and to create a new R&D funding mechanism for innovation in the space of technical infrastructure and data interoperability for global learning communities.
Membership
We are currently bringing on charter organizational members and will soon make an announcement highlighting these contributors. The institute will also offer individual memberships starting soon.
I2IDL is governed by a board of directors. The institute will host government, industry, and academic advisory councils — and you are encouraged to reach out if you have interest in participating.
The institute’s Technical Steering Committee is responsible for advising the board on the maintenance and development of our open source policy and data conformance resources — beginning with conformance tests for xAPI and xAPI Profiles as well as capabilities for Learning Metadata, Shareable Competency Definitions, and Enterprise Learner Records.

Mission Pillar A: Sustainable Core Open Source TLA Infrastructure
I2IDL will maintain and operate essential open source systems required for global learning data interoperability research:
Canonical xAPI conformance test suites
xAPI Profile Server and related linked-data services
TLA reference implementations
Shared metadata, competency, and learner record schemas
Machine-enabled capabilities and human-led advisory to ensure full TLA conformance and accreditation based on the model of ADL’s TLA Maturity Model
Continued support for and standards alignment with the IEEE Learning Technology Standards Committee and outreach and partnership with allied standards organizations
Mission Pillar B: Public-Good R&D for Data InteroperabilIty
I2IDL will create a new hub for research and innovation in learning and training technologies:
Competitive research grants
Public-private research partnerships
University collaborations
Technology incubation and spin-out pathways for TLA-based innovations
Why Now?
Because in an age of AI proliferation, it is ever more crucial to ensure the promise of data interoperability to increase transparency, verifiability, and accessibility.
