ReqXChanger – The Gearwheel between Requirements and Modeling

The Willert ReqXChanger offers an interface between requirements management and modeling tools, providing synchronisation of requirements and related information. It supports common requirements management tools, such as DOORS and Polarion, and the leading UML / SysML modeling solution – IBM Rational Rhapsody. Further, it supports the widely established UML tool Enterprise Architect from Sparx Systems.
By using the ReqXChanger, you are able to make a complete traceability and impact analysis for your requirements and your model elements.

New and noteworthy in ReqXChanger 2.0.0:

  • DOORS Compability: Improved roundtrip compability with DOORS. Now allows for using a ReqIF Specification in DOORS again and again and when merging, deleted UML elements will be marked as deleted.
  • Bugfix: EA Roundtrip: Catch Exception when EA API is unable to get element for ID from connector end.
  • Bugfix: <identifier> could not be used as a requirement identifier correctly
  • Rhapsody: Handle enum literal names “new” and “default” and add postfix, as Rhapsody does not allow for enum literals with these names
  • Bugfix: improve reliability for creating visualization stereotype on roundtrip
  • EA Roundtrip: extended error message when inspecting invalid trace dependencies (EA Connectors)
  • EA: EA Repository Option: Fixed that ODBC Connection strings were not shown if they were set as option value. Any String is considered as a valid value now.

Known Issues

  • When using multiple documents, ensure, that the used Identifier is unique when exporting multiple documents into one Root Package. For DOORS: Use separate root packages for each ReqIF document from DOORS. You may also now use the new feature for custom roundtrip ID to ensure a unique roundtrip document ID to merge the document in your RM tool.
  • For roundtripped descriptions of UML artifacts, line breaks cannot be considered currently.
  • DOORS cannot handle the default XHTML format for formatted text in ReqIF, so that roundtripped test results will not be displayed properly.
  • DOORS will show UML diagram images as a shortcut symbol, which you must select in order to see the diagram picture

Upgrade from previous version

Upgrade from version 1.4.1:

  • Just extract and start the new version
