PAIRSE
Type: National project
(ANR)
Duration: November 2009 -
October 2012
Description:
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.
SemEUsE
Type: National project
(ANR)
Duration: January 2008 -
June 2010
Description:
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. My role within this project is to
propose and implement a novel approach for integrating context in
service discovery and composition.
SCOrWare
Type: National project
(ANR)
Duration: January 2007 -
December 2008
URL: www.scorware.org
Description:
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.
SUPER
Type: : Integrated
project-Contract: IST 026850 “Semantics Utilised for Process
management within and between enterprises”
Duration: 2006 - 2009
URL: http://ip-super.org/
Description:
Business Process Management
focuses on managing the execution of IT-supported business
operations from a business expert's process view rather than from a
technical perspective. The underlying motivation for BPM is that
organizations need to continuously align their running business
processes, as executed within multiple heterogeneous systems, with
the required processes as derived from business needs. BPM has
gained significant attention in both research and industry, and a
range of BPM tools are available. However, the degree of
mechanization in BPM is currently very limited. The major obstacle
preventing a coherent view on business processes is that the
business processes are not accessible to machine reasoning.
Additionally, businesses cannot query their process space by logical
expressions, e.g. in order to identify activities relevant to comply
with regulations. Founded on ontologies Semantic Web technology
provides scalable methods and tools for the machine-readable
representation of knowledge. Semantic Web Services (SWS) make use of
Semantic Web technology to support the automated discovery,
substitution, composition, and execution of software components (Web
Services). BPM is a natural application for Semantic Web and SWS
technology, because the latter provide large-scale, standardized
knowledge representation techniques for executable artefacts. Our
proposal is to combine SWS and BPM, and develop one consolidated
technology. Specifically, we will create horizontal ontologies which
describe business processes; vertical telecommunications oriented
ontologies to support domainspecific annotation for our chosen
economic sector; and a suite of tools based on the results of the
SEKT and DIP IPs. Together with the other SDK1 projects this will
further strengthen the global leadership of EU-funded technology
development.
INTEROP
Type: : Network of
Excellence-Contract IST-508011 “Interoperability Research for
Networked Enterprises Applications and Software
Duration: 2003 - 2006
URL:
http://www.interop-noe.org/
Description:
World-class competitiveness of
European Enterprises, including SMEs, strongly depends, in the
future, on their ability to concretise massively and rapidly
networked dynamic organisations. New Technologies for
Interoperability within and between enterprises, have to emerge to
radically solve the recurrent difficulties - largely due to the lack
of conceptual approaches - encountered to structure and interlink
enterprises' systems (information, production, decision).Today,
research on Interoperability of Enterprise Applications does not
exist as such at the European level. As a result of the IST Thematic
Network IDEAS, the roadmaps for interoperability research emphasises
the need for integrating three key thematic components:- Ontology to
identify interoperability semantics in the enterprise- Enterprise
Modelling to define interoperability requirements- Architectures and
Enabling Technologies to provide implementation frameworks.INTEROP
aims to extract value from the sustainable integration of these
thematic components and to develop industrially significant new
knowledge. Network's role will be to create the conditions of a
technological breakthrough to avoid that enterprise investment be
simply pulled by incremental evolution of IT offer. To ensure
efficient industrial impact, INTEROP proposes, as a validation and
dissemination strategy, to have strong interactions with IPs in the
same domain of interest, like ATHENA in which the major
enterprise-oriented IT providers are involved, in particular
regarding future standardisation.The Joint Programme of Activities
aims to:- integrate the knowledge in Ontology, Enterprise Modelling
and Architectures to give sustainable sense to interoperability-
structure the European research community and influence
organisations' programmes to achieve critical research mass- animate
the community and spread industrially significant research knowledge
outside the network.
