ONAR: An Ontologies-based Service Oriented Application Integration Framework

The evolving technologies of Semantic Web and Web services are providing new means for application integration frameworks. The need for semantically enriched information exchange over the flexible environment of the internet provides a valuable enhancement to traditional methods and technologies for Enterprise Application Integration. However the utilization of the Semantic Web and Service Oriented Architecture (SOA) is not as straightforward as it appears and has specific limitations and inefficiencies due to the fact that is was not originally designed for that purpose. This paper presents a methodology that aims at the exploitation of these two technologies and the definition of an ontologies based enterprise application integration framework (ONAR).

TraceALL: a semantic web framework for food traceability systems

Purpose – The purpose of this paper is to describe TraceALL which is a Semantic Web (SW), ontology‐based, service‐oriented framework which aims to provide the necessary infrastructure enabling food industry (particularly SMEs) to implement traceability applications using an innovative generic framework.Design/methodology/approach – The framework builds upon the idea of the Semantic Web and provides an open and extensible underlying platform that allows different traceability interconnected applications to be designed and developed. More specifically, the framework provides a formal, ontology‐based, general‐purpose methodology to support knowledge representation and information modelling in traceability systems. Additionally, it suggests an open application framework based on widely used Semantic Web standards. Finally it provides a set of core services for storing, processing and retrieving traceability information in a scalable way. These components, taken together, facilitate the efficient development o...

FUSE: A framework to support services unified process

Traditional methodologies for Software development life cycle such as the Unified Process or the Object Oriented Process, Environment and Notation (OPEN) are proven to be flexible and robust for developing traditional Information Systems. However in the new SOC (Service Oriented Computing) paradigm large systems emerge comprised of self contained building blocks: the services, which can be combined to form complex business processes located in different servers and companies, where users may customize and create their services dynamically and negotiate Service Level Agreements electronically. In such systems the traditional software development methodologies are simply inefficient. This paper presents the FUSE approach which provides a methodology and a framework to be used both by the IT industry and individuals with little or no IT-experience, such as specific domain experts, end users, testers and community members. This will support their common efforts in the efficient development of more reliable Service Oriented systems of the future. FUSE Framework is based and makes use of the Unified Process, OPEN, extended participatory design (PD) and other similar methodologies.

PANDA: a virtual breeding environment for SMEs in the ERP/CRM industry using a service oriented approach

PANDA is a European Union co-funded Information Society Technologies project examining innovative aspects of e-collaboration in the European enterprise resource planning/customer relationship management (ERP/CRM) industry of small and medium enterprises (SMEs). One outcome of PANDA is an advanced business-to-business (B2B) web-platform, dedicated to serving as a virtual breeding environment (VBE) for the ERP/CRM industry. PANDA introduces a system with a service-oriented architecture (SOA) approach, which includes request-based virtual organisations (RBVOs), i.e., flexible clusters reflecting international ERP/CRM value chains, comprised of ERP/CRM vendors, their national representatives, dealers and consultants. RBVOs are facilitated by a community of intelligent agents. The paper discusses the objectives of PANDA, illustrates its main concepts, briefly outlines the operations and explains the architecture of PANDAs system.

MO-BIZZ: Fostering Mobile Business through Enhanced Cloud Solutions

Mobile devices are becoming more powerful and are able to support applications of significant size and high processing efforts. However, most of the applications require mobile internet connections to use information and services of background infrastructures. Especially business applications for mobile devices consisting of a dashboard that provides the user with information and a service orientated architecture behind which provides the correspondent services to collect the required information. The development of such a business application and the background service infrastructure requires not only lots of know-how, but is also very expensive. This paper presents the MO-BIZZ platform that allows businesses to rapidly develop and offer new services to their customers. In fact, the MO-BIZZ platform enables autonomous organizations to deploy additional services and the combination and validation of existing cloud-based services from third-party provider. Thus, companies are able to save money for developing common business functionality and a complex background infrastructure for its provisioning. The challenge of this innovative technology is not only related to the development of a business model that shall facilitate rapid service conceptualization, but rather the service level agreements that need to be dynamically negotiated and accepted on different levels of the MO-BIZZ stack.

From Patient Information Services to Patient Guidance Services-The iCare Approach

The provision of the Health services in the EU despite the evolvement of ICT follows a rather traditional path were the patient is totally dependable from his/hers doctors seeking guidance for every decision he/she needs to take related to his/her condition. The vision of the iCare approach is to provide better support to patients from the comfort of their home. This paper presents a new innovative approach to improve Patient Guidance Services (PGS). iCare approach takes full advantage of Semantic Web technologies and IoT and provides a new approach that would put the demands of the patient in the center and exploiting the available sources it will offer patient guidance services reducing dramatically the patient dependency from his/her doctors.

A Service Oriented and Agent-Based Architecture for the e-Collaboration of SMEs

The concept of a Service-Oriented Architecture (SOA) to flexibly address business needs with the use of Information Technology (IT) is increasingly being recognized as important for a company’s agility and responsiveness to change. A SOA approach can also help to design more agile web portals, in order to enable companies to increase their responsiveness and adaptability with regards to addressing a business opportunity as a collaborative Virtual Organization (VO). Value can be added to the operations of such a VO with the use of Intelligent Agents to automate the processes of finding collaboration partners and negotiating the creation of VOs based on user-defined business rules. This paper discusses these concepts and their benefits for Virtual Organizations based on the work of a European Union (EU) co-funded Information Society Technologies (IST) project examining these issues for Small and Medium Enterprises (SMEs) in the European Enterprise Resource Planning (ERP) industry.
