This article is intended to introduce and share tailored searches for SysML Requirements in Sparx Enterprise Architect modelling tool.

Enterprise Architect built-in requirements have been customized by Sparx Systems according to the OMG SysML specifications by adding the following properties:

  • text: The textual representation or a reference to the textual representation of the requirement.
  • id: The unique id of the requirement.

Text and id are available as tagged values, illustrated below.

When standard (non-SysML) requirements are used, it is common practice to run searches on the title, alias (reference) and notes (description). When possible, a systems project team can choose to use these fields in SysML requirements as an alternative to the OMG "id" and "text" properties.

Instead if the id et text tagged values must be used, there can be issues in running searches based on Enterprise Architect default installation.

That's why I ended up defining the following SysML searches, available via the UMLChannel MDG Technology.
