Interoperability framework for integrated e-health services

As one of the country with largest population in the world, Indonesia is facing major challenge to serve people in various sectors, one of them is health sector. Utilization of Information and Communication Technology (ICT) has a strategic role in improving efficiency and expanding services access. The main challenge related to data interoperability is the ability to integrate and synchronize data sourced from health information (e-health) systems with different (heterogeneous) platforms. This research aims to build a framework to materialize data interoperability and information exchange among e-health systems. The interoperability is materialized by utilizing service oriented architecture (SOA) paradigm and is implemented using Web Service technology. Service oriented analysis and design (SOAD) is used as method in the system development at the analysis phase and designing phase to generate service portfolio which consisting of three levels: conceptual view, logical view, and physical view. This research intruduces Interoperability Matrix (IM) to describe the modules and entities that involved in the framework design. The framework resulted from this research can be used as reference in e-health systems development in variety of health care applications.

Agile Service-oriented Analysis and Design of Industrial Internet Applications

This paper highlights the importance of systematic agile service engineering for Industrial Internet and Industrie 4.0 software applications. Here, the functional and non-functional requirements of IT users (mostly from the disciplines of mechanical engineering and electrical engineering) need to be mapped to the capabilities of emerging service platforms. The capabilities of service platforms are usually described, structured and formalized by software architects. However, very often, their description does not fit to the language of the user. This complicates the transition from requirements analysis to system design. The paper describes how this ‘gap’ may be closed with help of a service-oriented analysis and design (SOAD) methodology entitled SERVUS and a corresponding Web-based collaborative tool that supports the documentation according to the SERVUS design methodology. SERVUS denotes a Design Methodology for Information Systems based upon Service-oriented Architectures and the Modelling of Use Cases and Capabilities as Resources. It describes individual design activities interconnected by a common modelling environment (based upon the REST principles) combining several viewpoints of architectural reference model, e.g. the RAMI4.0 Business, Information and Functional Layers. SERVUS was successfully used in numerous collaborative and inter-disciplinary software projects.

Data and Metadata Exchange Design with SDMX Format using Web Service for Interoperability Statistical Data

Today’s concept of Open Government Data (OGD) for openness, transparency and ease of access of data owned by government agencies becomes increasingly important. This initiative emerges from the demand of data users for the data belongs to the government agencies. The data services providing an easy access, cheap, fast, and interoperability are needed by the users and becomes important indicator performance for respective government agencies. Statistical Data and Metadata Exchange (SDMX) is a new standard format in the data dissemination activities particularly in the exchange of statistical data and metadata via Internet. In this respect SDMX support the implementation of OGD project. This paper is on the technical design, development and implementation of data and metadata exchange service of statistical data using SDMX format to support interoperability data through web services. Three results are proposed: (i) framework for standardization of structure of statistical publications data model with SDMX; (ii) design architecture of data sharing model; and (iii) web service implementation of data and metadata exchange service using Service Oriented Analysis and Design (SOAD) method. Implementation at Statistics Indonesia (BPS) is chosen as a case study to prove the design concept. It is shown through quantitative assessment and black box testing that the design achieves its objective. DOI: http://dx.doi.org/10.11591/telkomnika.v14i2.7505

A survey of agent-oriented software engineering for service-oriented computing

Services play an increasingly important role in software applications today. Service-Oriented Computing (SOC) increases the speed of system development through loose coupling between the system components, the discovery of services and consolidating multiple heterogeneous services. However, the present conventional approaches to engineering SOC systems are not able to address the complexities of open and dynamic environments, such as those in an extended virtual enterprise or in interorganisation workflows. This is the first survey paper for Agent-Oriented Software Engineering (AOSE) to be applied to SOC. In this paper, we have also identified the critical challenges for Service-Oriented Software Engineering (SOSE) and how agent-based techniques can be applied to address these challenges. The paper surveys and evaluates a number of models and methodologies that attempt to tie in two domains of software engineering, namely, Agent-Oriented Analysis and Design and Service-Oriented Analysis and Design (SOAD).
