We see the connection.
I2IDL advances open infrastructure, interoperable data, standards, and research for learning, training, and education.
Build, steward, and explain the infrastructure behind connected learning.
Keep essential learning infrastructure available.
Conformance resources, reference implementations, metadata, competencies, learner records, and the shared technical foundations that interoperable learning systems depend upon.
Meet the Technical Steering Committee →Advance the field.
Research, standards participation, public-private collaboration, and experimentation around learning data, Learning Engineering, AI, and interoperable ecosystems.
Meet the board →Make the field easier to understand and use.
Public documentation, webinars, technical guidance, foundational research, and an expanding glossary of digital learning terminology.
Open the glossary →A shared language for digital learning.
The I2IDL Digital Learning Glossary brings authoritative sources together in one searchable reference, with term-level provenance and source licensing preserved.
AI makes interoperability more important, not less.
Learning systems are generating and consuming more data across more platforms. Shared standards and open infrastructure make that data easier to exchange, inspect, validate, and use responsibly.
Understand how learning data is structured, exchanged, and interpreted across systems.
Use shared specifications and conformance practices to test whether systems behave as expected.
Keep foundational infrastructure and knowledge available beyond any single vendor or institution.
The pieces that let learning systems work together.
I2IDL's technical work begins with the resources needed to make standards operational, testable, and useful across real learning ecosystems.
Experience API (xAPI) Specification
The open specification for recording and exchanging learning activity and experience data across systems.
LRS Conformance Test Suite
Conformance testing resources used to verify whether Learning Record Stores implement required xAPI behaviors.
xAPI Profiles
Specification and supporting resources for defining shared vocabularies, templates, and patterns for xAPI implementations.
Why I2IDL exists.
I2IDL was established in late 2025 as an independent nonprofit steward of open learning-data infrastructure and as a new mechanism for research and innovation in interoperability.
Ensuring Learning and Training Data Infrastructure and Interoperability Research Beyond ADL
The institute's founding paper describes the need for a durable, non-governmental home for essential open-source learning infrastructure and for continued public-good research in interoperability.
