Note:Blue nodes highlight the most important element in the diagram

The key element of an XPDL file is the package element. It contains one or several individual processes (e.g., Diabetes management)


A workflow process consists of one or multiple activities (e.g., Determine diabetes onset, Check current diabetes medication, Obtain most recent diabetes lab results (HbA1c)).


There are many different types of activities defined. The most important type is activity of a ‘Task’ implementation type. (e.g., EHRGetLabData(PatientID, LabTestCode), or EHRRegisterAlertMessage(PatientID,BloodPressureNotAtGoalMessage)
