Learner profile management for collaborating adaptive eLearning applications

Adaptive Learning Systems would perform better if they would be able to exchange as many relevant fragments of information about the learner as possible. The use of Web Services standards is recently gaining the attention of many researches as a promising solution for the problem of interfacing adaptive hypermedia systems. Existing Web Service standards, however, only provide very basic features and leave out many important issues like transactional management. In this paper we propose a mechanism for enabling consistency maintenance of Learner Profiles shared between collaborating adaptive learning systems.
