Like its predecessor
SCORM, was instigated by the
United States Department of Defense. • Learning Tools Interoperability, formerly called Basic LTI, was originated in 2008 as a
Google Summer of Code project. It was developed by Jordi Piguillem under the mentorship of
Charles Severance and Marc Alier. • In June 2010, Learning Tools Interoperability version 1.0 was finalized. • In August 2012, Learning Tools Interoperability version 1.1 introduced a feature allowing external tools to send grade results back to the originating learning system. • In January 2014, Learning Tools Interoperability version 2.0 was launched, introducing
REST-based two-way communication between external tools and the learning platform. Simultaneously, a subset of version 2.0 was released as version 1.2, as a transitional update from version 1.1 to version 2.0. • Due to their complexity, adoption of Learning Tools Interoperability version 1.2 and version 2.0 was slow. Consequently, IMS Global learning consortium reclassified them to as “legacy specifications”, advising against upgrading from Learning Tools Interoperability version 1.1 due to security concerns. • In May 2019, the IMS Security Framework and Learning Tools Interoperability version 1.3 were published based on
OAuth2,
OpenID Connect, and
JWT. Learning Tools Interoperability version 1.0, version 1.1, version 1.2 and version 2.0 were all deprecated. ==Adoption==
