diff specific for CDISC reports

CDISC Changes Report Generator v2.1

This program will generate a changes report between two CDISC releases. The releases may span any amount of time.

Requirements (with install commands for *nix gurus)

Git (sudo apt-get install git)

Apache Ant (sudo apt-get install ant)

Java Developers Kit (sudo apt-get install openjdk-8-jdk)

Building the program

Download this entire project as a .zip.


Clone the DiffCDISC repository onto your local filesystem using Git:

C:> git clone https://github.com/NCIEVS/nci-diff-CDISC.git

Open a Command Prompt and navigate to the repository directory.

Run an ant build

C:\DiffCDISC> ant build

This will create a 'classes' and add a jar file to the 'dist' directory where program dependancies are stored. The program is now ready to run.

NOTE: If the build fails, you may need to inspect your ant configurations. See: https://ant.apache.org/manual/

Preparing data for the program

Users should pull two reports in .txt format from the same EVS CDISC Archive directory (e.g., ADaM, SDTM, SEND).

Included in this repository are two example reports from the SDTM Archive directory. The example below will demonstrate how to run the program using these two files.

Running the program

Each report is input into the program (newest followed by oldest), followed by a "release date" and then the filename of the output.

C:\DiffCDISC\dist>RunChanges "..\docs\SDTM Terminology 2015-09-25.txt" "..\docs\SDTM Terminology 2015-06-26.txt" "9/25/2015" Changes.txt

Known issues

The 'Request Code' column will always be empty as they are stored in the JIRA tracking system. This column is manually populated by EVS before each quarterly release.

Version 2.0 was implemented in 2015 Version 2.1 was implemented after Q2 2017

Release notes between 1.0 and 2.0

  1. Initialize the diff program if and only if there are 4 program arguments
  2. The "Request Code" column values no longer appear as "unknown" (they are now empty)
  3. Reported changes on non-differing Codelists have been removed
  4. Report changes on removed Codelists
  5. Verbaige updates to "Change Types" ("Add" or "Remove" on "CDISC Synonyms" is now just "Update" for existing codelists.)
  6. Improved handling of inputs

2.0 and 2.1

  1. Default character set for input Scanner is now windows-1252 to allow reported differences on special characters such as non-breaking spaces.
