  ABSTRACT = {Approaches to self-adaptive software systems use models
  at runtime to leverage benefits of model-driven engineering (MDE)
  for providing views on running systems and for engineering feedback
  loops. Most of these approaches focus on causally connecting
  runtime models and running systems, and just apply typical MDE
  techniques, like model transformation, or well-known techniques, like
  event-condition-action rules, from other fields than MDE to realize
  a feedback loop. However, elaborating requirements for feedback
  loop activities for the specific case of runtime models is rather
  neglected. Therefore, we investigate requirements for Adaptation
  Models that specify the analysis, decision-making, and planning of
  adaptation as part of a feedback loop. In particular, we consider
  requirements for a modeling language of adaptation models and for a
  framework as the execution environment of adaptation models. Moreover,
  we discuss patterns for using adaptation models within the feedback
  loop regarding the structuring of loop activities and the implications
  on the requirements for adaptation models. Finally, we assess two
  existing approaches to adaptation models concerning their fitness for
  the requirements discussed in this paper.}
