• Visit-based, repeating: A repeatable scheduled or unscheduled occurrence (e.g., Cycles in Oncology trials, Unscheduled Visits)
• Common, repeating: An unscheduled but repeatable occurrence (e.g., Adverse Event)
• Common, non-repeating: An unscheduled, one-time occurrence (e.g., Termination)

• Items – individual data fields (e.g., blood pressure, date of visit).
• Constraints – rules that define acceptable input values (e.g., numeric ranges, required fields).
• Relevance logic – conditional rules that show or hide fields based on prior responses.
• Calculations – auto-derived values (e.g., BMI from height and weight).
• Metadata – labels, instructions, and coding standards to ensure consistent data entry.

Users with the appropriate level of form access can enter data into a Form.
