| Name | Description | Modifies Slot |
|---|---|---|
| Condition | A reusable, composable, and nestable logical construct allowing for complex expressions. Conditions are most useful when given a meaningful name and linked to Study Definitions. | no |
| RangeCheck | A validation element that performs a simple comparison check between a referenced item's value and specified values, resolving to a boolean result | no |
| Method | A reusable computational procedure that describes how to derive values and can be referenced by Items. Analysis and Derivation concepts can be implemented by a Method. Properties can be referenced by Parameters in its expressions. |
no |
| Analysis | Analysis extends Method to capture analysis-specific metadata including the reason for analysis, its purpose, and data traceability for the results used. Expressions and parameters from Method can be generic or implementation-specific. |
