Collaboration Contexts, Services, Events and Actions: Four Steps Closer to Adaptive Collaboration Support in IMS LD

The IMS Learning Design specification, a widely known language for modelling collaboration scripts, has been criticized for a number of shortcomings and general lack of support for comprehensive adaptation features. We propose concrete extensions to the specification, aiming to alleviate deficiencies by specifically addressing (group) collaboration contexts, flexible service specification, fine-grained event handling and a wide range of adaptive interventions to support learners.
