Resource Management
Scenario 3
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)
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.

Resource Discovery
Scenario 4
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.

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
