Table 2 Context data model and xAPI comparison
From: Enriching context descriptions for enhanced LA scalability: a case study
Name | Unit of focus | Flexibility of data registration | Categorization of context | Interoperability | Usage |
|---|---|---|---|---|---|
LOCO | Learning object | More rigid | No categorization | Targets interoperability | Personalization, examine object use |
CAM | Learner | Flexible | No categorization | Targets interoperability | Personalization, visualization, examine object use |
LCDM | Learner | More rigid | Two-level categorization (high/low level) | Targets interoperability | Visualization |
RCM | Learner | More rigid | Two-level categorization (high/low level) | Does not target interoperability | Personalization/contextualization, visualization |
xAPI | Learner/ agent | Flexible | No categorization | Targets interoperability | Personalization, visualization, examine object use, assessment, prediction, etc. |
