This presentation is a case study that starts at the business needs and drills down to specific implementation problems with both Web Services and XML including an example of the transformation to legacy transaction format and a discussion of WebSphere/.NET Web Service integration issues, e.g. making DIME work. There will also be a discussion of the current criminal justice XML standardization initiatives, e.g. Department of Justice XML Data Dictionary effort and the standardized XML criminal history "rap sheet". The case study is not a story about sophisticated use of XML. It is about improving information sharing and improving operational efficiency for a very important mission.
