RSM to TOPCASED transformation

This transformation is an extract of a Topcased import process that allows to transform RSM diagrams in a the Topcased formalism. Normally, this process is done in three distinct parts which are :

• a preprocessing step done in Java
• an ATL transformation
• a postprocessing step done in Java

Here only the second part is presented and isolated to be tested for the ATL benchmark.

To get more information about this topic, a full presentation can be found here : [1].

Currently only the class diagrams and usecase diagrams are processed in this version.

• name of the input metamodel : RSM.ecore
• name of the output metamodel : Topcased.ecore
• name of the input model : Topcased.rsm - size : ~6 Mb
• name of the output model : Topcased.umldi - size : ~900Kb

Benchmark environment

Hardware

• Processor : Pentium IV 2.80 GHz
• RAM : 1024Mo

Software

• Operating system : Linux Mandriva
• JVM : JRE 1.5
• Eclipse 3.3 Europa
• ATL 2.0

Changes between V0 (original) et V1 (optimized)

• use of inheritance rules when it is possible.
• use the method refImmediateComposite() to find parent element (avoid to use custom code to browse the model)
• declare constants using attribute helpers.
• replace method helpers without parameters by attribute helpers.
