This report presents the implementation of the import/export of User Requirements Notation (URN) models in Z.151 format with jUCMNav. Z.151 is an ITU-T standard for the URN language. jUCMNav is an Eclipse plug-in for the design and analysis of URN models. The current jUCMNav files are in XML/XMI format complying with jUCMNav’s metamodel. To better comply with the Z.151 standard, jUCMNav needs to support importing/exporting of URN models in Z.151 XML files.

This project led to the following contributions:
  • We have implemented (with JAXB) a new functionality for the jUCMNav application: the import/export of URN models in the standard Z.151 format.
  • We have supported a bi-directional transformation between the standard Z.151 meta-model (November 2008) and the jUCMNav metamodel version 0.23 (December 21, 2009).
  • We have tested the import and export with a set of simple URN models and a comprehensive set of existing URN models.
  • We have found six errors in the Z.151 XML schema, which will be sent to ITU-T as a contribution to improve the Z.151 standard.
With the above contributions, jUCMNav becomes the first tool to support the standard Z.151 file format.
