The MedBiquitous Virtual Patient standard provides a common XML format for describing computer-based clinical simulation for medical education, including Virtual Patient Data (patient demographics, clinical data, narrative text, and educational feedback), media resources, data availability model (allows for aggregations of data to be constructed), activity model (creates paths through the content and dictates how the learner interacts with the virtual patient), and a player specification (indicates how a player interprets other components for delivery to the learner).
