Learning Tools Interoperability™



IMS is developing Learning Tools Interoperability (LTI)™ to allow remote tools and content to be integrated into a Learning Management System (LMS).

Version 2.0 - Public Draft Specification

LTI v2 has been under development for several years and provides a more sophisticated and extensible platform to enable deeper integrations and greater support for services and events. LTI 2 builds on LTI 1 by incorporating more sophisticated outcomes reporting and a rich extensions architecture allowing additional services to be added gradually. LTI 2 uses REST and JSON-LD to deliver this new functionality.

LTI Version 2.0 Reference Implementation:

See a screen recording of LTI v2.0 in action using a simple Tool Consumer and Tool Provider developed by John Tibbetts of VitalSource. John explains the prototype work he has done with LTI v2.0 and demonstrates the new features and functionality available. VitalSource developed this code and has offered it to the IMS member community while the LTI workgroup continues development of the conformance certification program.

Overview of LTI v1.0: http://www.vimeo.com/14100773
This is a recorded presentation about the IMS Learning Tools Interoperability standard from imsglobal.org. This talk gives a high-level technical overview of LTI and talks about how Basic LTI connects to IMS Common Cartridge (CC) and IMS Learning Information Services (LIS). This also talks about the status of market adoption amongst the LMS vendors and tool providers.
