  • FSN OCCIWare (December 2014 - November 2017): The OCCIware project aims at proposing a formal model-driven approach for managing Everything as a Service with the Open Cloud Computing Interface (OGF OCCI). OCCIware will be composed of three pillars: 1) a formal specification of OCCI with Alloy, 2) an Eclipse model-driven tool chain, and 3) a Models@run.time support called erocci.
  • FSN Open-PaaS (June 2012 - February 2015): The Open PaaS project aims at developing a PaaS (Platform as a Service) technology dedicated to enterprise collaborative applications deployed on hybrid clouds (private / public). Open PaaS is a platform that allow to design and deploy applications based on proven technologies provided by partners such as collaborative messaging system, integration and workflow technologies that will be extended in order to address Cloud Computing requirements.
  • ITEA EASI-CLOUDS (November 2011 - November 2014): Extendable Architecture and Service Infrastructure for CLOUD-computing Software. The objective of EASI-CLOUDS is to provide a comprehensive cloud computing infrastructure that will feature the three classical categories of cloud computing offerings: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) with superior reliability, elasticity, security and ease-of-use characteristics at all levels. The major expected outcome consists of a comprehensive, open-source, innovative, and validated cloud infrastructure that can be instantiated to set up an application type-specific cloud (e.g., e-learning, HPC-on-demand, storage marketplace) for a private, public, or hybrid usage, and implementing a given level of security, privacy and QoS. Such instances will be able to interoperate in different ways and constitute a federation of cloud computing systems.
  • FUI CompatibleOne (November 2010 - October 2012): CompatibleOne aims at providing an open, interoperable, evolutive and standard broker allowing to create, deploy and manage private, public or hybrid cloud platforms. The CompatibleOne broker is based on open standards, mainly CDMI and OCCI, and uses our new defined object-based description to model and manage the various Cloud resources that manipulates the main CompatibleOne platform.
  • ANR PAIRSE (November 2009 - October 2012): PAIRSE address the challenges of heterogeneity and efficient query-processing for the need of data sharing in P2P environments, by advancing a web service-based approach and by taking into account the data privacy dimension. To the best of our knowledge, a service-based approach for data integration has not been explored yet and very few works have been proposed to take into account the data privacy needs when data are shared. In this proposal, the access to the data sources will be performed by a new class of web services called: Data-Providing Web servise (DP) which are different from the traditional web services named Effect Providing Web services (EP), in that their invocation only returns data but does not have effects that may change the surrounding environment. Assuming that autonomous information systems expose their data in the form of DP services and specify a set of privacy policies to protect sensitive and confidential data, and given a user query expressed in SPARQL query language over an RDFS ontology, this project will focus on how Web services could be discovered, selected and composed to efficiently cover the user query.
  • ANR SemEUsE (January 2008 - June 2010): The SemEUsE project specifically aims at providing a context-aware semantic service architecture addressing both the design phase, thanks to theoretical context-aware semantic service models and policy-oriented design patterns, and the runtime phase, thanks to a Dynamic Semantic Service Bus. This extended service bus is based on a static and dynamic service composition engine so that the current execution context and particular requirements (related, for example, to nomadic constraints) can be continuously taken into account. A dynamic monitoring system, using CompositeProbes, will also be connected to the orchestration process so that QoS aware late binding can be implemented.
  • ANR SCOrWare (January 2007 - December 2008): The SCOrWare project aims at providing an open source implementation of the recent Service Component Architecture (SCA) specifications defined by the Open SOA collaboration, an industrial consortium in the domain of software engineering, including BEA Systems, IBM Corporation, IONA Technologies, Oracle, Red Hat, Rogue Wave Software, Siemens, Sun Microsystems, and Sybase. Briefly, SCA defines a new architecture and programming model for Service Oriented Applications (SOA) based on the component paradigm and supporting several service description languages such as WSDL and Java interfaces, several programming languages such as Java, C++, and BPEL, several communication protocols between applications such as SOAP, CORBA, Java RMI, and JMS. My role within this project is semantic description and discovery of SCA components.
  • ITEA S4ALL (July 2005 - June 2007): S4ALL aimed to allow users to create and share mobile and user centered services as easy as it is for web pages. The project addresses two main issues: the service-creation process and the associated service execution environment. Service creation will become much simpler, thanks to graphical tools based on manipulation of icons representing existing services or capabilities; this will allow anyone to create or customize their own mobile and personalized services. An enhanced middleware layer will permit the implementation of service oriented architecture (SOA) principles such as a loosely coupled approach, generalized semantic publishing and discovery, and fast and automatic deployment of components. It also allow anyone to host and manage their services on a personal computer (PC) or mobile terminal, thanks to the use and improvement of ObjectWeb open-source solutions such as open-source cluster application resources (OSCAR) and Java open application server (JOnAS). My role in this project was centered on service description and composition.
