2. Separation of Concerns in CADMOS
 The design of a Learning Unit is done in two
steps, thus creating two design views/models:
 Conceptual Model or Learning Activity design view
 Flow Model or Learning Activity flow design view.
 The Learning Activity Design View defines the
learning activities of the actors and the
resources/services that support these activities.
 The Learning Activity Flow Design View
captures the orchestration of the learning
activities

3. Conceptual Model - Learning Activity design view

6. Concluding remarks
 CADMOS v1.6
 Promotes a step wise design approach
 Allows traceability in the design process
 Allows to focus on a specific view and to reuse design
views
 CADMOS LDs conform to IMS LD level A,B
 CADMOS v1.7
 Conformance with IMS LD Level C
 Include design patterns as templates
 Embedded interoperabitiy with Moodle
