An export .twx file is the means for exchanging information between Business Process Manager (BPM) and IBM® Integration Bus.
You can use IBM Integration Bus to implement, test, and deploy requested services for Business Process Manager (BPM) business applications. You use an export .twx file to exchange artifacts when they are created or modified in one tool, exported, then imported into the other tool. The export .twx file is a compressed text file in a proprietary format with snapshots of process applications and BPM toolkits. You import export .twx files into the IBM Process Designer repository and into IBM Integration Bus.
In Business Process Manager, you can export process applications and toolkits in the
Business Process Model Notation (BPMN) and export .twx file formats.
However, only the export .twx file format provides the data that is
needed by IBM Integration Bus. For more information about the
contents of the export .twx file and exporting in BPM, see IBM Business
Process Manager product documentation online and look for exporting process
applications.
