LONS: Learning Object Negotiation System.

This system comes up as a result of the increase of e-learning systems. It manages all relevant modules in this context, such as the association of digital rights with the contents (courses), management and payment processing on rights. There are three blocks: - A normalized application following the worldwide accepted standards or recommendations (SCORM, IMS, IEEE, etc.) containing the courses and implementing the organization of users and their subscriptions in the courses. - Another application will be in charge of managing the digital rights of the courses following ODRL [1]. It considers the creation of these courses, its offers with different costs and its requirements. - In order to negotiate the digital rights it is necessary another application implementing a device to manage and make payments using the secure payment methods currently used in the network.
