DESCRIPTION: \n\nAbstract\n\n \n\nIn modern software systems\, software mod
 ellers often use different modelling languages and views to describe the c
 haracteristics of a complex system. This multi-language system allows mode
 llers to express a specific system characteristic with the most appropriat
 e modelling languages and notations. With the proliferation of independent
 ly developed and continually evolving modelling languages\, it becomes mor
 e challenging to reuse or combine multiple languages in a multi-language m
 odelling environment. Also\, language models are collectively used to deve
 lop a system\; hence\, it is essential to keep the models consistent. Howe
 ver\, it is still a difficult task to maintain the consistencies across th
 e language models and\, as well\, to support the independent evolution of 
 the modelling languages. Moreover\, a modeller needs to navigate model ele
 ments that describe a system to understand and modify the system under dev
 elopment. However\, generic navigation of model elements is a daunting tas
 k without dedicated support from the modelling environment.\n\nIn this doc
 toral thesis\, we present a framework for the specification and developmen
 t of multi-language systems based on perspectives to promote modularity in
  language reuse\, inter-language consistency\, combination of languages\, 
 and generic navigation of model artefacts. A perspective groups different 
 languages for a modelling purpose\; defines the role of each participating
  language\; and specifies a generic navigation mechanism to traverse diffe
 rent model elements. Furthermore\, a perspective defines composite actions
  for building a consistent multi-model system and maintaining the links be
 tween different model elements.\n\nThe aim of this framework is to streaml
 ine the combination of multiple languages in a system and allow the perspe
 ctive designer to focus only on specifying relationships between different
  languages. A generative approach then ensures appropriate language regist
 ration\, model consistencies\, and generic navigation of model elements. H
 ence\, a designer is freed from the error-prone implementation of consiste
 ncy and navigation mechanisms.\n\nWe evaluate our approach with a perspect
 ive (Fondue Requirement) aimed at requirement elicitation and specificatio
 n that combines five different languages. This perspective illustrates how
  a perspective designer can leverage our framework to register languages\,
  specify perspectives\, and then generate the implementation of the perspe
 ctive. In addition\, we analyse language actions for the five languages to
  demonstrate the benefits of perspective actions. To ensure the completene
 ss and correctness of our approach\, we further evaluate our framework wit
 h two notable multi-language modelling environments: User Requirements Not
 ation and Palladio Component Model. Here\, we focus on the relationships b
 etween different languages in each perspective and show how our approach h
 andles them.\n
