Official Turnitin Deep Integration Module
From MoodleDocs
nLearning Limited developed a new Moodle integration as an activity module for a client. This integration (like Dan Marsden’s) is a deep integration. Unlike Dan’s it has been kept abstracted from the core and as a result will work in Moodle versions from 1.8 upwards. iParadigms (as of 9 July 2009) have taken on support of this integration within the core of the Turnitin application and have extended the API to accommodate this type of solution.
