==History==

* Learning Tools Interoperability, formerly called BasicLTIBasic LTI, was originated in 2008 as a [[Google Summer of Code]] project. It was developed by Jordi Piguillem under the mentorship of [[Charles Severance (computer scientist)|Charles Severance]] and Marc Alier.<ref>{{cite web|url=https://code.google.com/p/basiclti4moodle/ |title=basiclti4moodle - Implements a IMS BasicLTI Consumer for Moodle - Google Project Hosting |date=2012-07-02 |accessdate=2015-09-07}}</ref>

*In June 2010, Learning Tools Interoperability version 1.0 was finalized.<ref>{{cite web|url=http://www.imsglobal.org/lti/index.html#lti1.1 |title=Learning Tools Interoperability® |publisher=IMS Global |date= |accessdate=2015-09-07}}</ref>

*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.<ref>{{cite web|url=http://www.imsglobal.org/LTI/v1p1p1/ltiIMGv1p1p1.html |title=IMS Global Learning Tools Interoperability Implementation Guide Version 1.1.1 |publisher=Imsglobal.org |date= |accessdate=2015-09-07}}</ref>

*In January 2014, Learning Tools Interoperability version 2.0 was launched, introducing [[Representational state transfer|REST]]-based two-way communication between external tools and the learning platform.<ref>{{cite web|url=http://www.imsglobal.org/lti/ltiv2p0/ltiIMGv2p0.html |title=IMS Global Learning Tools Interoperability Implementation Guide Version 2.0 Final |publisher=Imsglobal.org |date= |accessdate=2015-09-07}}</ref> 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"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 [[JSON Web Token|JWT]]. Learning Tools Interoperability version 1.0, version 1.1, version 1.2 and version 2.0 were all depreciated.<ref>{{cite web|url=https://www.imsglobal.org/lti-adoption-roadmap |title=Recommended LTI Adoption Roadmap and FAQ |publisher=Imsglobal.org |date= |accessdate=2018-06-07}}</ref>
