CFP: REBLS 2017 - 4th International Workshop on Reactive and Event-Based Languages & Systems 4rd International Workshop on Reactive and Event-Based Languages & Systems Held at SPLASH Conference http://2017.splashcon.org/ Vancouver, Canada - October 23rd, 2017 =====  Introduction  ===== Reactive programming and event-based programming are two closely related programming styles that are becoming ever more important with the advent of advanced HPC technology and the ever increasing requirement for our applications to run on the web or on collaborating mobile devices. A number of publications on middleware and language design - so-called reactive and event-based languages and systems (REBLS) - have already seen the light, but the field still raises several questions. For example, the interaction with mainstream language concepts is poorly understood, implementation technology is in its infancy and modularity mechanisms are almost totally lacking. Moreover, large applications are still to be developed and patterns and tools for developing reactive applications is an area that is vastly unexplored. This workshop will gather researchers in reactive and event-based languages and systems. The goal of the workshop is to exchange new technical research results and to define better the field by coming up with taxonomies and overviews of the existing work. ===== Contributions ===== Even though reactive programming and event-based programming are  receiving ever more attention, the field is far from mature. This  workshop will join forces and try to gather researchers working on the  foundational models, languages and implementation technologies. We  welcome all submissions on reactive programming, aspect- and  event-oriented systems, including but not limited to: Language design, implementation, runtime systems, program analysis,    software metrics, patterns and benchmarks. Study of the paradigm: interaction of reactive and event-based    programming with existing language features such as object-oriented    programming, mutable state, concurrency. Advanced event systems, event quantification, event composition,    aspect-oriented programming for reactive applications. Functional-reactive programming, self-adjusting computation and    incremental computing. Applications, case studies that show the efficacy of reactive     programming. Empirical studies that motivate further research in the field. Patterns and best-practices. Related fields, such as complex event processing, reactive data    structures, view maintenance, constraint-based languages, and their    integration with reactive programming. IDEs, Tools. Implementation technology, language runtimes, virtual machine support,    compilers. Modularity and abstraction mechanisms in large systems. Formal models for reactive and event-based programming. The format of the workshop is that of a mini-conference. Participants  can present their work in slots of 30mins with Q&A included. Because of  the declarative nature of reactive programs, it is often hard to understand  their semantics just by looking at the code. We therefore also encourage  authors to use their slots for presenting their work based on live demos. =====  Submissions ===== REBLS encourages submissions of two types of papers: Research results: complete works that ill be published in the ACM    digital library. In progress papers: papers that have the potential of triggering an    interesting discussion at the workshop or present new ideas that    require further systematic investigation. These papers will not be    published in the ACM digital library. Info about the format and the page limits can be found on the REBLS'17 website (http://2017.splashcon.org/track/rebls-2017). =====  Important dates ===== Papers deadline:               August 1, 2017 Papers notification:           September 5, 2017 Workshop:                      October 23rd, 2017 ==== Organization Organizers: Guido Salvaneschi, TU Darmstadt Wolfgang De Meuter, Vrije Universiteit Brussel Patrick Eugster, Purdue University and TU Darmstadt Lukasz Ziarek, SUNY Buffalo ===== REBLS @ SPLASH 2017
