In this deliverable, we present a significant extension of the Situation Action Network (SAN) modeling framework, with the appropriate notions and mechanisms in order to alleviate a part of the modeler’s effort during the design of SAN trees and increase their run time flexibility. This extension involves the capability to automatically select appropriate primitive actions based on real time evaluated criteria using multi-criteria decision making (MCDM) methods and techniques. We formally present this extension, we discuss the necessary SAN engine extensions and we conclude with two illustrative scenarios one concerning the Event subscription Recommender (ESR) and one the Service Adaptation Recommender (SAR) that exhibit the necessity of Action Pools in SANs.

The present document provides the state of the art about all issues that will be considered in PLAY. In section 3, we discuss middleware approaches for event-based and federated service-oriented architectures (SOA), while in section 4 we present complex event processing approaches used so far. Then in section 5, we indicate the state of the art on interactions between people, services and events that encapsulate principles and tools for triggers and event-based application of adaptations in service-based systems. In section 6, we present the overview of relevant research projects, mostly funded by the European Commission, while in section 7 we refer to the standards that are relevant to PLAY project.

This deliverable elaborates on the requirements that are needed for the development of the PLAY system. The requirements are derived from the use cases by performing comprehensive AsIs and ToBe analyses. SCube methodology is used as a basis for performing these analyses.

This deliverable gives a bird’s eye view on the general architecture of the system and should lay a foundation for the integration of all components. Each component will be described through its functional and non-functional requirements.

This deliverable gives an overview of the challenges underlying the Event Cloud component, positioning it in the state of the art, and sketching a preliminary possible solution (both algorithmic and from a software engineering viewpoint) to support its publish/subscribe functionality.

The  platform  is  composed  of  several  software  components. These components are linked together using the platform event approach. Distributed systems such as this one need to be monitored. Firstly, because platform managers must  be  able  to  detect  failures  and  points  of  optimization  and  lastly  because agreements  can  be  established  between  the  platform  and  the  users. The  goal  of  the  current  deliverable  is  to  describe  the  approach  used  to  create  an
extensible and efficient monitoring framework for the PLAY distributed platform.

The purpose of this deliverable is the identification of requirements to support Distributed CEP in an elastic manner and to provide a first sketch at approaching elasticity.

Introducing Event Subscription Recommender (ESR) and Service Adaptation Recommender (SAR) components specifications along with the notion of Situation-Action-Networks (SANs) as formalism in order to address the main objectives of WP4, for managing the interaction between users, events and services. 

We develop and report in this deliverable an aspect-oriented extension to BPMN2.0 and we couple it with an event-driven approach for detecting and reasoning about situations that require adaptation of business processes.

Describing the scenarios and the mandatory components (Web Services, applications) built to implement the Taxi use-case.

Describing the scenarios and the  construction  of  the  simulation  platform  built  to simulate   various   collaborative   workflows,   actors’ behaviour, and event production during the response to a nuclear crisis.

This deliverable describes all the activities conducted and  results  achieved  considering  the  dissemination of PLAY project results during the first project year.
