  18. CoLab’s operation principlesAccess Control By pattern matching on the resource’s URI. Conditions based on user role/actions: • Visits per user; • Precondition on documents; • Required score; • Time-based conditions. Conditions based on other users actions: • Access condition on roles; • Competition condition. • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  19. CoLab’s operation principlesAdaptability Based on: • User profile: e.g. user’s language… • Connection bandwidth: e.g. ISDN, modem… • Equipment performance: PDA, laptop, workstation… • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  21. e-Learning through the use of CoLab CoLab seems to be the good choice for e-Learning, since it implements: • Asynchronous browsing: students and professors consult and review the available material, students solve exercises and evaluations, professors review exercises and evaluations… • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  22. French version English version e-Learning through the use of CoLab CoLab seems to be the good choice for e-Learning, since it implements: • Adaptability: resources presented are adapted to the user’s profile, connection bandwidth and equipment performance (when available)… • Spanish language documents are presented to students whose profile language is Spanish; • Special compact version of the material is presented to users accessing using a PDA. • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  23. e-Learning through the use of CoLab CoLab seems to be the good choice for e-Learning since it implements: • Synchronous browsing and communicating: a professor gives a lecture, supervises the students learning activities, or students have virtual teamwork at their own decision; • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  24. e-Learning through the use of CoLab CoLab seems to be the good choice for e-Learning since it implements: • Dynamic evolving access control: users have the right to access learning material, and other resources, depending on their current role, the time, the user’s past actions, as well as the past actions performed by other users… • Document X can only be accessed by a given user iif document Q has previously been accessed by that same user; • Document Y is accessible only on workdays (Monday – Friday) from 9:00 to 17:00 until September 30; • Document Z can only be accessed by a user of role A iif no user of role B has accessed it. • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  26. Conclusions and Perspectives • Conclusions: • The Web can be successfully used for group-oriented e-Learning; • Dynamic behavior on Web-based e-Learning systems are good for learners; • The current implementation satisfies the requirements to validate that such proposal is fully implementable. • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives

  27. Conclusions and Perspectives • Perspectives: • Keep working in the definition of the fine-grain aspects of the Access Control system; • Integrating all the necessary tools within CoLab; • Interfacing CoLab with Virtual Reality; • Exploring the possibilities of extending this work for implementing a Social-Web. • Introduction • e-Learning and the Web • CoLab’s operation principles • e-Learning through the use of CoLab • Conclusions and perspectives
