IMS/LTI plugin

Version 1.5.1 (beta)

This plugin is meant to be later integrated into Chamilo (in a major version release).

IMS/LTI defines the possibility to integrate tools or content into Chamilo. This plugin allows the integration of a new tool into courses, obtaining data back from those tools and recording them as gradebook "external" activities.

As a platform admin, you can register external tools available for all courses. You need set the tools settings in the IMS/LTI administration page. Then the registered tools should be added in each course individually.

As a teacher, you can register external tools available only for the current course. You need follow the link in the IMS/LTI block located in the Course Settings tool. Then select a previously tool registered or register a new external tool.
