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.
