Contextual Components of an Enterprise Architecture Framework for Pan-European eGovernment Services

Enterprise Architecture (EA) frameworks provide a wide range of architecture components. Contextual EA components provide the necessary guidance to design specific architectures in a given context e.g. for Pan-European Government Services (PEGS). Contextual EA components help to describe the background and scope of architecture work and provide a ground to tackle architecture challenges in an agreed way. The main contribution of this conceptual paper is to connect existing theoretical models as a basis to examine contextual components of an EA framework for PEGS. Three aspects are elaborated using a model-based approach: a Critical Success Factor Model, a Strategy Management Model and a Stakeholder Engagement Model. The identified models are aligned with EA standards and provide guidance to empirical research and to programs, projects and initiatives that wish to create interoperability architectures

The enterprise blockchain design framework and its application to an e-Procurement ecosystem

The research work of this paper has been partially funded by the project VORTAL INTER DATA (n° 038361), co-financed by Vortal and COMPETE Program P2020. We would also like to thank UNIDEMI, DEMI, and LASI for providing us with the research infrastucture and resources to conduct this research. Publisher Copyright: © 2022 Elsevier LtdBlockchain technologies have seen a steady growth in interest from industries as the technology is gaining maturity. It is offering a novel way to establish trust amongst multiple stakeholders without relying or trusting centralised authorities. While its use as a decentralised store of value has been validated through the emergence of cryptocurrencies, its use case in industrial applications with multiple stakeholder ecosystems such as industrial supply chain management, is still at an early stage of design and experimentation where private blockchains are used as opposed to public blockchains. Many enterprise blockchain projects failed to gain traction after initial launches, due to inefficient design, lack of incentives to all stakeholders or simply because the use of blockchain was not really necessary in the first place. There has been a need for a framework that allows blockchain designers and researchers to evaluate scenarios when a blockchain solution is useful and design the key configurations for an enterprise blockchain solution. Literature on blockchain architectures are sparse and only applicable to specific use cases or functionalities. This paper proposes a comprehensive Enterprise Blockchain Design Framework (EBDF), that not only identifies the relevant use cases when a blockchain must be utilised, but also details all the characteristics and configurations for designing an enterprise blockchain ecosystem, applicable to multiple industries. To validate the EBDF, we apply the same to the Vortal e-Procurement ecosystem allowing for multiple platforms to interoperate with greater transparency and accountability over the proposed blockchain framework. In this use case, many vendors bid for procurement procedures, often for publicly managed funds where it is extremely vital that full transparency and accountability is ensured in the entire process. Ensuring that certain digital certification functions, such as timestamps are independent from e-Procurement platform owners has been a challenge. Blockchain technology has emerged as a promising solution for not only ensuring transparency and immutability of records, but also providing for interoperability across different platforms by acting as a trusted third-party. The applied framework is used to design a Hyperledger based blockchain solution with some of the key architectural elements that could fulfil these needs while presenting the advantages of such a solution.publishersversionpublishe

Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)

The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers

Developing front-end Web 2.0 technologies to access services, content and things in the future Internet

The future Internet is expected to be composed of a mesh of interoperable web services accessible from all over the web. This approach has not yet caught on since global user?service interaction is still an open issue. This paper states one vision with regard to next-generation front-end Web 2.0 technology that will enable integrated access to services, contents and things in the future Internet. In this paper, we illustrate how front-ends that wrap traditional services and resources can be tailored to the needs of end users, converting end users into prosumers (creators and consumers of service-based applications). To do this, we propose an architecture that end users without programming skills can use to create front-ends, consult catalogues of resources tailored to their needs, easily integrate and coordinate front-ends and create composite applications to orchestrate services in their back-end. The paper includes a case study illustrating that current user-centred web development tools are at a very early stage of evolution. We provide statistical data on how the proposed architecture improves these tools. This paper is based on research conducted by the Service Front End (SFE) Open Alliance initiative

Archetype based intelligent system for healthcare interoperability

Tese doutoramento - Programa Doutoral em Engenharia BiomédicaThe healthcare arena configures an environment of both complexity and cooperation, in which numerous and distinct information systems must exchange information in a expedite and consolidated manner. Where healthcare interoperability is concerned several techniques, methodologies, architectures and standards exist. However subjects such as service distribution, fault tolerance, standards, communication flavoring and tightly-bound systems still are a major issue of concern. This work studies and researches the best methodologies to imbue intelligent behaviours combined with ontology and moral awareness into multi-agents system applied to healthcare environments. Its core objective is to propose, develop, implement and evaluate an archetype for an interoperability platform oriented towards the healthcare environment. This archetype was validated in several implementation in different major healthcare institutions. It is based in an agent framework named JADE and is adapted and oriented towards the healthcare environment. Henceforth the resulting archetype addresses the existing limitations in past and present solutions regarding healthcare interoperability. It explores the limits of intelligent behaviours in multi-agent systems applied to interoperation procedures in healthcare, towards the improvement of the reliability and quality of information exchanged.A área da saúde configura um ambiente de grande complexidade e cooperação onde inúmeros e distintos sistemas de informação têm que trocar informação entre si de uma forma expedita e consolidada. No âmbito da interoperabilidade hospitalar existem várias técnicas, metodologias, arquiteturas e standards. No entanto, temas como distribuição de serviços, tolerância à falha, standards, flavouring de comunicações e sistemas fortemente acoplados, continuam a ser um importante fonte de preocupação. Este trabalho estuda e pesquiza as melhores metodologias de embeber comportamentos inteligentes combinados com ontologias e noções morais em sistemas multi-agentes aplicados a ambientes hospitalares.
