eautils feature list 9

eaUtils 1.19.6 introduces a new feature to compare diagrams.

Native feature in Enterprise Architect

Enterprise Architect provides a baseline comparison tool to compare the current state of the model in the database with a "baseline" i.e. an XMI export of a model branch. This is relevant and convenient to compare the model with an older state when snapsnots (baselines) are available.

For more information, search for model baseline in Enterprise Architect User Guide.

Alternative approach with eaUtils

eaUtils Compare Diagrams feature provides a different approach by running a comparison on the content from 2 diagrams, to identify differences in terms of elements and connectors visible in each diagram.  

An Enterprise Architecture model built with ArchiMate (Open Group) illustrates the purpose in this article.

The following diagrams establish the current and future states of the organization's main applications flows i.e. before and after a planned migration to replace "Application 2" with "NewAPP A" and "NewAPP B" applications.

Current state with "Application 2":

Future state with "NewAPP A" and "NewAPP B":

Procedure to use eaUtils Compare Diagrams:

  • Create a new diagram where eaUtils will be executed.
  • Add a hyperlink for each diagram to compare (drag and drop each diagram and select Hyperlink).

Compare diagrams

  • Set the hyperlinks alias values as follows:
    • Diagram 1 alias = eautils_compare_v1
    • Diagram 2 alias = eautils_compare_v2

Compare diagrams diagram 1 alias

  • The setup is complete. Right click on this diagram and select Specialize > eaUtils > [Diagrams] Compare Diagrams
  • The following window is opened with the status update:

Run Compare Diagrams

  • Note: an error is displayed if the diagram is not properly set up.

  • Result
    • A diagram is generated with the elements and connectors from both diagrams.
    • Elements and connectors with the border line in RED were only found in Diagram 1 i.e. they can be considered as removed from Diagram 2.
    • Elements and connectors with the border line in GREEN were only found in Diagram 2 i.e. they can be considered as added in Diagram 2.
    • Other elements and connectors with the default border line were found in both diagrams (matching).
    • A legend is available.

  • This diagram can be finalized and saved:

It is also possible to set a different colour from the default red and green. To do so, update each hyperlink font (text) colour e.g. diagram 1 = blue and diagram 2 = orange.

Compare Custom colours

Running eaUtils Compare Diagrams feature generates the following result:
