The jQAssistant XMI Plugin provides scanners and rules for importing UML models, e.g. from XMI files. These models may be used by constraints to verify

Prerequisites

• Java 8 or higher

• Maven 3.5.x or higher

• jQAssistant 1.10.0 or higher (see below)

Setup

Maven

The plugin can be enabled by adding it as a dependency to the jQAssistant Maven plugin.

1. Adds a folder to be scanned by the jQAssistant Maven plugin, any contained .xmi file will be scanned.

2. Declares the UML plugin as dependency.

Command Line Utility

Download the JAR file from Maven Central and put it into the /plugins folder of the distribution.

Executing the command jqassistant.sh scan -f src/xmi/ (Linux) or jqassistant.cmd scan -f src/xmi/ will scan any file with the extension .xmi located in the given folder.

Sprint PetClinic Example

The folder src/example/spring-petclinic of this project contains a Spring PetClinic based example for using the XMI plugin to define components and their dependencies. Refer to the file jqassistant/index.adoc for a detailed step-by-step description of the jQAssistant setup and rules.

Tip	To view full metadata of embedded rules (e.g. required concepts) switch to Raw mode.

Reference Documentation

XMI File Scanner

The plugin provides a scanner which accepts files with the extension .xmi and creates the structure as described in this section, using :XMI:File as entry point.

Overview

The scanner creates nodes with the following labels:

• :XMI:File

  • :XMI:Documentation

  • :XMI:Stereotype

    • :XMI:AppliedStereotype

  • :XMI:Element

  • :UML:Model

    • :UML:PackagedElement

      • :UML:OwnedAttribute

      • :UML:OwnedEnd

      • :UML:Interface:Required

Rules

The plugin provides concepts for extracting UML models, e.g. for

• labeling :UML:PackagedElement nodes having xmiType=uml:Component as :UML:Component.

• creating (:UML:Component)-[:HAS_DEPENDENCY]→(:UML:Component) relations from :PackagedElement nodes having xmiType=uml:Dependency.

Furthermore a group xmi:UML is provided which allows easily applying all UML related concepts.

The rules including their descriptions are defined in the file /META-INF/jqassistant-rules/xmi.xml.
