The Fifth International Model-Driven Requirements Engineering (MoDRE) workshop continues to provide a forum to discuss the challenges of Model-Driven Development (MDD) for Requirements Engineering (RE). Building on the success of MDD for design and implementation, RE may benefit from MDD techniques when properly balancing flexibility for capturing varied user needs with formal rigidity required for model transformations as well as high-level abstraction with information richness. MoDRE seeks to explore those areas of requirements engineering that have not yet been formalized sufficiently to be incorporated into a model-driven development environment. Reuse of requirements models and management of requirements at runtime become distinct possibilities with MDD and model transformations. This workshop intends to identify new challenges, discuss on-going work and potential solutions, analyze the strengths and weaknesses of MDD approaches for RE, foster stimulating discussions on the topic, and provide opportunities to apply MDD approaches for RE. The workshop is co-located with the 23rd IEEE International Requirements Engineering Conference (RE 2015) in Ottawa, Canada, in August 2015. Accepted papers will become part of the workshop proceedings and will be submitted for inclusion into the IEEE Digital Library.
