Special topics We plan to have dedicated sessions in the program on the following three special topics (details below): Configurable Systems in the DevOps Era, Microservices, and Techniques to reason about interacting digital contracts. SCOPE Modern information systems rely increasingly on combining concurrent, distributed, mobile, adaptive, reconfigurable and heterogeneous components. New models, architectures, languages and verification techniques are necessary to cope with the complexity induced by the demands of today’s software development. Coordination languages have emerged as a successful approach, in that they provide abstractions that cleanly separate behaviour from communication, therefore increasing modularity, simplifying reasoning, and ultimately enhancing software development. Building on the success of the previous editions, this conference provides a well-established forum for the growing community of researchers interested in models, languages, architectures, and implementation techniques for coordination. MAIN TOPICS OF INTEREST Topics of interest encompass all areas of coordination, including (but not limited to) coordination related aspects of: - Theoretical models and foundations for coordination: component composition, concurrency, mobility, dynamic, spatial and probabilistic aspects of coordination, logic, emergent behaviour, types, semantics; - Specification, refinement, and analysis of architectures: patterns and styles, verification of functional and non-functional properties, including performance and security aspects; - Dynamic software architectures: distributed mobile code, configuration, reconfiguration, networked computing, parallel, high-performance and cloud computing; - Nature- and bio-inspired approaches to coordination; - Coordination of multiagent and collective systems: models, languages, infrastructures, self-adaptation, self-organisation, distributed solving, collective intelligence and emerging behaviour; - Coordination and modern distributed computing: web services, peer-to-peer networks, grid computing, context-awareness, ubiquitous computing, mobile computing; - Coordination platforms for infrastructures of emerging new application domains like IoT, fog- and edge-computing; - Programming methodologies, languages, middleware, tools, and environments for the development and verification of coordinated applications; - Tools, languages and methodologies for secure coordination; - Industrial relevance of coordination and software architectures: programming in the large, domain-specific software architectures and coordination models, case studies; - Interdisciplinary aspects of coordination; - Industry-led efforts in coordination and case studies. SPECIAL TOPICS COORDINATION 2021 is seeking contributions that enable the cross-fertilisation with other research communities in computer science or in other engineering or scientific disciplines. Depending on the quality of the contributions, we plan to have dedicated sessions in the program, possibly together with a panel discussion. 1. Configurable Systems in the DevOps Era Highly configurable software systems, such as software product lines, call for automatic mechanisms that allow to tame the complexity and variability. DevOps have pushed forward the importance of automating every step of the software development process, including the management of configurable systems. In this special topic, we welcome submissions addressing novel techniques and methodologies for the COORDINATION of automatic configuration tasks or for the COORDINATION of the various phases from development to deployment supporting the continuous release of software/products. Moreover, given the relevance of the topic to industry and aligned with the main topics of COORDINATION, we encourage submissions of efforts carried out in collaboration with industry, including case studies.

Microservices (in collaboration with the Microservices Community) Microservices are a novel architectural style, taking to an extreme the ideas of service-oriented computing. In microservices, applications are composed by loosely coupled entities, the microservices. Beyond that, single microservices should be small enough to be easily managed, modified, and if needed removed and rewritten from scratch. Microservices aim at obtaining high flexibility, reconfigurability and scalability, thanks also to the exploitation of containerization technologies such as Docker. Given that microservice-based applications are composed of many loosely-coupled microservices, techniques allowing one to coordinate their execution in order to obtain the desired behaviour are of paramount importance.

Techniques to reason about interacting digital contracts With the rise of blockchains and cryptocurrencies, digital contracts have become popular in the form of smart contracts, which encode a financial transaction between possibly distrusting parties using a distributed consensus protocol. Although smart contracts bear the potential to benefit society quite fundamentally (e.g., equalize access to financial infrastructure, increase fairness), the benefits are shadowed by the existence of severe security vulnerabilities in deployed smart contracts and smart contract languages. In the 2021 edition of COORDINATION, we are soliciting contributions on new programming language paradigms and patterns for expressing digital contract interactions, verification and analysis techniques for checking safety and liveness properties and guaranteeing correctness of digital contracts, as well as compositionality and scalability of digital contract reasoning techniques. Contacts: Stephanie Balzer (balzers@cs.cmu.edu <mailto:balzers@cs.cmu.edu>) and Anastasia Mavridou (anastasia.mavridou@nasa.gov <mailto:anastasia.mavridou@nasa.gov>) TOOL PAPERS We welcome tool papers that describe experience reports, technological artefacts and innovative prototypes (including engines, APIs, etc.), for coordinating, modelling, analysing, simulating or testing systems, as well as educational tools in the scope of the research topics of COORDINATION. In addition, we welcome submissions promoting the integration of existing tools relevant to the community. Submissions to the tool track must include an extended abstract and a link to a demo video that previews the potential tool presentation at the conference. Both the abstract and the video will be decisive criteria in the selection process. Authors of accepted contributions will be asked to produce a regular (full) paper to appear in the conference proceedings, which will be subject to a lightweight revision process. Interested authors can contact the tool track chairs: Giorgio Audrito (giorgio.audrito@unito.it <mailto:giorgio.audrito@unito.it>) and Silvia Lizeth Tapia Tarifa (sltarifa@ifi.uio.no <mailto:sltarifa@ifi.uio.no>) for details. SUBMISSIONS Important Dates January 29, 2021 — abstract submission February 5, 2021 — paper submission April 2, 2021 — notification April 23, 2021 — camera ready PUBLICATION Authors are invited to submit papers electronically in PDF using a two-phase online submission process. Registration of the paper information and abstract must be completed according to the DisCoTec submission dates. Submissions are handled through the EasyChair conference management system, accessible from the conference web site: https://easychair.org/conferences/?conf=coordination2021 <https://easychair.org/conferences/?conf=coordination2021> Contributions must be written in English and report on original, unpublished work not submitted for publication elsewhere (cf. IFIP’s Author Code of Conduct, see http://www.ifip.org/ <http://www.ifip.org/> under Publications/Links). The submissions must not exceed the total page number limit (see below) prepared using Springer’s LNCS style. Submissions not adhering to the above specified constraints may be rejected without review. Submission categories - Full papers (up to 15 pages + 2 pages references): describing thorough and complete research results and experience reports. - Short papers (up to 6 pages + 2 pages references): describing research in progress or opinion papers on the past of Coordination research, on the current state of the art, or on prospects for the years to come. - Survey papers (up to 25 pages + 2 pages references): describing important results and successful stories that originated in the context of COORDINATION. - Tool papers (up to 6 pages + 2 pages references): describing technological artefacts in the scope of the research topics of COORDINATION. The paper must contain a link to a publicly downloadable MPEG-4 demo video of at most 10 minutes length. The authors of accepted papers (in any submission category) will be encouraged to make their artefacts publicly available using permanent repositories such as Zenodo etc. (for Tool papers, the tool should already be available at submission time for reviewing purposes, but not necessarily via a permanent archive with a DOI). The conference proceedings, formed by accepted submissions will be published by Springer in the LNCS Series. Special Issues Following the tradition of previous editions of COORDINATION, according to the quality and number of the submission, we will organise special issues of extended and selected Full/Short/Survey/Tool papers in reputable journals such as LMCS (Logical Methods in Computer Science) and SCP (Science of Computer Programming). Special issues for last year’s edition are under preparation and we will advertise them on the conference’s website as soon as they get published.
