4.3 Types of SER
In order to acknowledge the heterogeneity of metadata requirements put forward by the different concepts, the IRM explicitly differentiates between two types of SERs: Educational Activity Descriptions, and Educational Content.
An Educational Activity Description is understood as a machine-readable documentation of a sequence of measures users can get involved in order to achieve an educational objective. Educational Activity Descriptions represent the dynamic part of the domain model. They can range from micro formatted documentations of learning events (e.g. a public guest lecture) to full-fledged descriptions of units-of-learning as proposed by IMS LD.
In the dynamic part of the domain model the IRM further differentiates between run-time and design-time concepts. Hence, design time concepts such as Learning or Assessment Designs refer to the design-time part of delivering teaching and learning, while concepts such as Learning and Assessment Opportunity refer to the run-time part.
Educational Content addresses the static part of the domain model and subsumes all educational resources that can be used or are created as a result of an educational process. It subsumes the concepts: Learning Outcome, Learning Content, Assessment Resource, Personal Achievement Profile, and Evaluation Resources.
