Rule Information

• Standard: ADaM
• Rule ID: 64
• Rule Description: The rule checks for presence of TRTxxAN and non presence of TRTxxA in ADSL

Describe the problem How to handle the subscripts on the variable names metadata, which xx ranges from 01-99. If the numerical variable is present e.g TRT01AN then TRT01A must also be present.

Describe the solution Solution was discussed at weekly meet, where variables would be extracted and compared to/matched to a regular expression to confirm presence. This would use the exisiting reg_match operator to compare against general pattern e.g 'value: ^TRT[0-9]{2}AN*' . This part currently exists.

However the solution proposes a new operation using regex via a find and replace operation using regex capture buffers to extract the xx value from the primary variable and use this to create the shorten name (minus the "n") of the second variable. This will then be used to define the second predicate in the rule logic.

Proposed rule logic yaml

Check: all:

• name: variable_name # e.g. TRT11AN operator: matches_regex # test 1 exist clause value: ^TRT[0-9]{2}AN*$

  new test clause using the new operation

• name: $generated_variable_name # TRT11A operator: is_not_contained_by value: variable_name # e.g. returns column vector [TRT11AN, ABCDE, FGHIJ] Operations:
  • find: ^TRT([0-9]{2})AN*$ id: $generated_variable_name name: variable_name operator: regex_find_replace replace: TRT\1A # uses capture buffer to extract xx and create secondary variable.
