Improvements to the G-Lorep Federation of Learning Object Repositories.

The G-Lorep project of the European Chemistry Thematic Network (ECTN), based on a federation of distributed repositories of Molecular Science Learning Objects, leverages at present a "hybrid" centralized/distributed architecture in which the central node hosts a shared database. The shared database deals only with the task of managing metadata in order to synchronize the information made available to the federation members at regular time intervals. To avoid security problems and reach a better code updating, the project has been migrated from Drupal CMS to Laravel framework. All modules have been written from the start, also a REST API server used as interface to the shared database is implemented and related performances are evaluated.
