Scenario 2 VLE User Accounts Users Web Browser MLE MLE User DB Academic User goes to MLE web site and queries SRS for details of students registered on his Module. SRS VLE The appropriate data is transferred from SRS to VLE using Specifications such as IMS Enterprise. XML Config File ANGEL User Manager The Academic then clicks the option to create and load a course/module in a specified VLE. ANGEL determines the appropriate protocols for querying the SRS and Creating accounts in the specified VLE.

Users Web Browser MLE MLE User DB Academic User has added a link to a resource, from a course page in the VLE, for all his students to use. VLE A Student User logs in to the Institutional MLE and follows the screens to the VLE (auto-login to VLE at appropriate position) Scenario 3 Resource Management XML Config File ANGEL Resource Manager The URL to the resource is a Search against ANGEL, and includes information about the users group and the resource ID. ANGEL determines where best to get that resource from, for members of THIS group.

Scenario 3 Resource Management Academic User has added a link to a resource, from a course page in the VLE, for all his students to use. A Student User logs in to the Institutional MLE and follows the screens to the VLE (auto-login to VLE at appropriate position) Appropriate cookies or certificates are transferred to the users machine and the browser is pointed to the required resource server, without the user having to login again. This uses Specifications such as Shibboleth and PAPI. XML Config File ANGEL Resource Manager Local & Remote Resources LMS The URL to the resource is a Search against ANGEL, and includes information about the users group and the resource ID. ANGEL determines where best to get that resource from, for members of THIS group. VLE Users Web Browser ANGEL transfers Cookie to Browser, and redirects Browser to point at appropriate resource

Scenario 4 Resource Discovery VLE When a student clicks this resource link, they could be presented with a number of options, including purchase information from the University Book Shop or Amazon, or just be presented with the electronic version directly. Scenario 3. Academic User goes to MLE web site and queries Library Services for resources on engineering. Once a single item is identified, a feature in the MLE allows the academic to associate the resource with a course and ask ANGEL to add it to the VLE resources page. Users Web Browser MLE MLE User DB Local & Remote Resources LMS ANGEL takes the Resource ID, the Course ID and the VLE reference and creates a search URL to insert in the VLE page.

authenticated networked guided environment for learning - secure integration of learning environments with digital libraries - Conclusion ANGEL can be used by other interface tools (VLE/MLE/ITE/Portals etc) ANGEL can support multiple systems (SRS/LMS/resource services) Used to support a wide range of tasks A number of Scenarios already implemented Many more scenario variations are possible
