=== Second Call for Papers === 24th International Symposium on Practical Aspects of Declarative Languages (PADL 2022) Philadelphia, Pennsylvania, United States 17-18th January 2022 https://popl22.sigplan.org/home/PADL-2022 Co-located with POPL 2022 Conference Description ---------------------- Declarative languages comprise several well-established classes of formalisms, namely, functional, logic, and constraint programming. Such formalisms enjoy both sound theoretical bases and the availability of attractive frameworks for application development. Indeed, they have been already successfully applied to many different real-world situations, ranging from database management to active networks to software engineering to decision support systems. New developments in theory and implementation fostered applications in new areas. At the same time, applications of declarative languages to novel and challenging problems raise many interesting research issues, including designing for scalability, language extensions for application deployment, and programming environments. Thus, applications drive the progress in the theory and implementation of declarative systems, and benefit from this progress as well. PADL is a well-established forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative programming, including functional and logic programming, database and constraint programming, and theorem proving. Topic of interest include, but are not limited to: - Innovative applications of declarative languages - Declarative domain-specific languages and applications - Practical applications of theoretical results - New language developments and their impact on applications - Declarative languages and software engineering - Evaluation of implementation techniques on practical applications - Practical experiences and industrial applications - Novel uses of declarative languages in the classroom - Practical extensions such as constraint-based, probabilistic, and reactive languages PADL 2022 especially welcomes new ideas and approaches related to applications, design and implementation of declarative languages going beyond the scope of the past PADL symposia, for example, advanced database languages and contract languages, as well as verification and theorem proving methods that rely on declarative languages. Submissions ----------- PADL 2022 welcomes three kinds of submission: * Technical papers (max. 15 pages) Technical papers must describe original, previously unpublished research results. * Application papers (max. 8 pages) Application papers are a mechanism to present important practical applications of declarative languages that occur in industry or in areas of research other than Computer Science. Application papers are expected to describe complex and/or real-world applications that rely on an innovative use of declarative languages. Application descriptions, engineering solutions and real-world experiences (both positive and negative) are solicited. * Extended abstracts (max. 3 pages) Describing new ideas, a new perspective on already published work, or work-in-progress that is not yet ready for a full publication. Extended abstracts will be posted on the symposium website but will not be published in the formal proceedings. All page limits exclude references. Submissions must be formatted according to the standard Springer LNCS style. The conference proceedings of PADL2022 will be published by Springer-Verlag in the Lecture Notes in Computer Science series. Work that already appeared in unpublished or informally published workshops proceedings may be submitted but the authors should notify the program chairs about the place in which it has previously appeared. PADL 2022 submissions are handled through the EasyChair conference management system: https://easychair.org/conferences/?conf=padl2022. Important dates (tentative) --------------- Abstract submission: 1 October 2021 (AoE) Paper submission: 8 October 2021 Notification of acceptance: 5 November 2021 Symposium: 17-18th January 2022 COVID-19 -------- PADL is co-located with POPL, which will take place January 16-22, 2022, as a physical, virtual, or hybrid physical/virtual meeting. We will be monitoring the Covid-19 situation and will announce a decision on the nature of the meeting in time which will follow suit with POPL. Distinguished Papers -------------------- The authors of a small number of distinguished papers will be invited to submit a longer version for journal publication after the symposium. For papers related to logic programming, in the journal Theory and Practice of Logic Programming (TPLP) https://www.cambridge.org/core/journals/theory-and-practice-of-logic-program..., and for papers related to functional programming, in Journal of Functional Programming (JFP) https://www.cambridge.org/core/journals/journal-of-functional-programming. The extended journal submissions should include roughly 30% more content including, for example, explanations for which there was no space, illuminating examples and proofs, additional definitions and theorems, further experimental results, implementational details and feedback from practical/engineering use, extended discussion of related work and such like. Invited Speakers ---------------- PADL 2022 features two invited talks by: - Marcello Balduccini (https://www.sju.edu/faculty/marcello-balduccini/) - Shriram Krishnamurthi (https://cs.brown.edu/~sk/) Chairs ------ - James Cheney, University of Edinburgh - Simona Perri, University of Calabria Programme Committee ------------------- Andres Löh, WellTyped Chiaki Sakama, Wakayama University Daniela Inclezan, Miami University Ekaterina Komendantskaya, Heriot-Watt University Esra Erdem, Sabanci University Francesco Calimeri, University of Calabria Jan Christiansen, Flensburg University of Applied Sciences Konstantin Schekotihin, University of Klagenfurt Lionel Parreaux, Hong Kong University of Science and Technology Marco Maratea, University of Genova Marina De Vos, University of Bath Martin Erwig, Oregon State University Martin Gebser, University of Klagenfurt Michael Greenberg, Stevens Institute of Technology Paul Tarau, University of North Texas Pavan Kumar Chittimalli, TCS Research, India Pedro Cabalar, University of Corunna Roly Perera, The Alan Turing Institute Tomas Petricek, University of Kent Torsten Grust, University of Tübingen Tran Cao Son, New Mexico State University Yukiyoshi Kameyama, University of Tsukuba
