20 | // consumer for Moodle 1.9 and Moodle 2.0. BasicLTI is a IMS Standard that allows web | |
21 | // based learning tools to be easily integrated in LMS as native ones. The IMS BasicLTI | |
22 | // specification is part of the IMS standard Common Cartridge 1.1 Sakai and other main LMS | |
23 | // are already supporting or going to support BasicLTI. This project Implements the consumer | |
