Comment: Removed "description" attribute from the list of attributes described for the Operation class and reordered "resultPattern" to be before "referencedOperationRelationships" for consistency with ER diagram

...

  • The id attribute contains the identifier value assigned for the operation.
  • The name attribute indicates the assigned name of the operation.
  • The label attribute contains a short label for the operation, such as might be shown in an output display (e.g., "n", "%", "Mean", "SD").
  • The description attribute may be used record a detailed description of the operation.
  • The referencedOperationRelationships attribute may be used to specify relationships to any other operations whose results are referenced in the calculation of the results for this operation, as described below.
  • The resultPattern attribute contains a textual representation for the default pattern or format used for the display of the results of this operation in output displays. The pattern should indicate the precision of the value to be displayed (e.g., "X.XXX") and may include parentheses or other additional characters (e.g., "(XXX.X)" or "±XX.XX"). In general, the pattern will usually be in the format that is displayed in output table shells, but sponsors may choose to use other pattern specifications.
  • The referencedOperationRelationships attribute may be used to specify relationships to any other operations whose results are referenced in the calculation of the results for this operation, as described below.

Some "dependent" operations may be defined to reuse the results of other "referenced" operations in the calculation of their result values. For example, an operation that calculates a percentage may reuse the results of other "count of subjects" operations to act as the numerator and denominator in the calculation of the percentage. In such operations, the referencedOperationRelationships attribute of the dependent operation is used to specify 1 or more relationships to the other referenced operation(s) whose results are used in the dependent operation's calculation. Each relationship is defined as an instance of the ReferencedOperationRelationship class, in which:
