IMS Basic LTI Overview

The document discusses Learning Tools Interoperability (LTI), a standard developed by IMS Global for integrating online learning applications and sharing user data between systems. It proposes LTI as a solution to the problem of different learning management systems having unique and incompatible ways of integrating external tools. The standard defines a common way for tools to launch and communicate within any LMS, addressing issues of development time and costs.

- 2. Learning Tools Interoperability Problem Every CMS has their own very unique "module", "tool" "block", "nugget", "powerlink", etc External tools like QuestionMark, Wimba, Elluminate, etc must prioritize which CMS they invest in plugging into Tool Providers wait until customers are willing to pay money to start development
- 3. Learning Tools Interoperability Solution Build a standard plug-in for all CMS systems Tool and Content Providers can build one integration and use it in any CMS that supports the standard Start simple and basic and then expand feature sets to allow market to adjust over time and insure that engineering due diligence is being done – phased release
