Objectives and Scope

Modern software systems are distributed, concurrent, mobile, and often involve the composition of heterogeneous components and of stand-alone services. Theoretical models, languages and tools for coordinating, composing and adapting services are hence required. They can indeed simplify the development of complex distributed service-based systems, enable functional correctness proofs and improve reusability and maintainability of such systems. In this context, the goal of the FOCLASA workshop is to gather researchers and practitioners of the aforementioned fields, to share their best practices and experiences, to identify common problems, and to devise general solutions in the context of coordination languages, service orchestration, and self-adaptive systems


Topics of interest include (but are not limited to):

Theoretical models and frameworks for component and service coordination, service composition, service adaptation and concurrent system modelling.

Applications and usability studies for the aforementioned theoretical models, interaction and coordination challenges in various application domains.

Languages and specification protocols for component and service interaction, their semantics, expressiveness, validation and verification, type checking, static and dynamic analysis.

“Software as a service” models (e.g., cloud/edge/fog computing) and dynamic software architectures, such as self-adaptive and self-organizing systems.

Tools and environments for the development of concurrent and customizable self-monitoring, self-adaptive and self-organizing applications.

Algorithms, mathematical models and realization frameworks for quality-of-service observation, storage, history-based analysis in self-adaptive systems.

Practice, experience and solutions from the following areas are solicited as well:

Blockchains and
distributed transactions.

Business process




Fog/edge computing

distributed systems.


Mobile computing




Call for papers

Contributions must be written in English and report on original, unpublished work not submitted for publication elsewhere. Full papers should be 15 pages long, including figures and references, and prepared by using Springer's LNCS style , Short papers (6 pages long) describing preliminary results or work-in-progress are encouraged as well. The contributions should be submitted as PostScript (PS) or Portable Document Format (PDF) files using the EasyChair submission site:

EasyChair FOCLASA 2018

All submissions will be reviewed by an international program committee who will make a selection among the submissions based on the novelty, soundness and applicability of the presented ideas and results. Concurrent submission to other venues (conferences, workshops or journal) and submission of papers under consideration elsewhere is not allowed.

All accepted papers will be included in the LNCS Workshop Post-proceedings of STAF 2018 , to be published by Springer after the workshop. Additionally, and following the tradition of past editions, the authors of a selected subset of papers will be invited to submit extended versions of their papers after the workshop, to be reviewed by a new set of reviewers, for publication in a special issue of a journal.

Invited Talks

Coordination of Complex Socio-technical Systems: Challenges and Opportunities by Stefano Mariani.
Abstract. Modern society is a growing interconnection of (sub)systems, such as healthcare, transportation networks, supply chain, etc. Its complexity thus stems from both the inherent complexity of each subsystem, and the added complexity of interactions amongst subsystems. The same can be said for modern IT systems, where managing interactions among components is at least as complex as designing the computational function of each component itself. To make the picture even more complicated, IT systems and the society rarely are isolated systems: rather, the latter relies on the former for many vital services and functionalities, giving birth to the so-called Socio-technical Systems. There, “humans-in-the-loop” are the norm rather than the exception, thus management of interactions further complicates: besides software-software, we now have software-human interactions to account for too. In this talk, we focus on interactions-not computation. Accordingly, we raise issues regarding modelling and designing coordination mechanisms and policies in this sort of systems - i.e. decentralisation, situatedness, accountability, emergence, etc. - and examine some possible solutions originating from the research area in coordination models and languages.

Microservices, microservices, microservices? by Antonio Brogi.
Abstract. In this talk we will critically discuss the main characteristics of microservices and the potentially huge advantages offered by their adoption for managing enterprise applications. We will also show how a simple formalization of the main properties of microservices can be exploited both to automate property checking and to drive the refactoring of existing applications.
