qvt

问题 At JPL, we use model transformation techniques for our systems engineering work. We use the Eclipse QVTO implementation of OMG's QVT specification. http://www.eclipse.org/modeling/m2m/downloads/index.php?project=qvtoml However, the Eclipse QVTO compiler is frustratingly slow. With judicious application of Guava's cache, I've managed to make significant performance improvements to the Eclispe QVTO compiler. More could be done but with what I have, I would like to get a view of the

问题 I guess this is quite a strange question about models transformation. I am starting from a UML 2.2 model defined with Rhapsody (IBM/Telelogic) and exported in XMI by means of the Rhapsody XMI toolkit. I have succesfully opened it with Topcased (The Eclipse based UML/Sysml modeling environment). I have therefore applied a QVT transformation to it, aimed at creating a new UML model with a specific subset of entities. Unfortunately i have not found the right way to retrieve entities description
