Representation Transformation. The purpose of the Representation Transformation is the generation of a textual description based on the intermediate model. The intermediate model is designed to have structure which is aligned to HiP-HOPS. No structural changes are required in this transformation. The focus is on serialising the model as text. Textual representations can be generated particularly well with model to text transformation languages. We chose the Xpand language from OpenArchitectureWare. Xpand is a template- based model transformation language, which incorporates the output in the form of templates into the control structure. The intermediate model is explored using a depth-first strategy. EAST-ADL models created in Papyrus have a metamodel that is a composition of several separate metamodels. In the case of EAST-ADL, the metamodel consists of the UML metamodel and the EAST-ADL profile. These artefacts are composed by the Eclipse Framework to an EAST- ADL metamodel at runtime. The EAST-ADL metamodel corresponding to a Papyrus EAST-ADL model is not a separate artefact, and this complicates the model transformation and limits the choice of model transformation engines.
