GIFT is Open Source and freely available.
The GIFT Project Team now believes that they have reached a stage where they can go public and are looking for volunteers to test and use GIFT, and to provide feedback so that it can be taken to the next level.
This looks like a very interesting and useful project, with lots of functionality.
GIFT is an empirically-based, service-oriented framework of tools, methods and standards to make it easier to author computer-based tutoring systems (CBTS), manage instruction and assess the effect of CBTS components, tools and methodologies. GIFT is being developed under the Adaptive Training Research Science & Technology project at the Learning in Intelligent Tutoring Environments (LITE) Laboratory, part of the U.S. Army Research Laboratory – Human Research and Engineering Directorate (ARL-HRED).
