ITI Technical Committee - Exploring a new approach to Audit Message Specification in the TF

During the Feb 2017 F2F Meeting in Naples, Italy, the ITI Technical Committee began exploring alternatives to specifying audit message requirements. This wiki page is a working document in order to make progress toward an improved specification

The problem

  • The current practice in the ITI TF is to specify audit message requirements in the Security Considerations section at the end of every transaction in Volume 2a, 2b, 2c. The tables are based on the General Message Format in DICOM PS3.15 Section A.5.2.
  • For new transactions, ITI does not have documented guidance for profile authors on how to fill out each field in an audit message/
  • The ITI TF does not have a template for the IHE conventions for specifying audit messages (use of fonts, etc)
  • Thus, for a new transaction, a common practice is for the author to copy an audit message specification for an existing transaction and then make edits. Authors have varying expertise in this area, and the original table may have had errors. This results in many errors that cascade into many, many CPs to fix audit message specifications.
  • Errors in the TF are then encoded into the Gazelle Security Suite and Gazelle EVS Client test tools that do audit message checks based on the TF requirements.
