Summary Objectives: EHR systems are core applications in any eHealth/pHealth environment and represent basic services for health telematics platforms. Standards Developing Organizations as well as national programs define EHR architectures as well as related design, implementation, and deployment processes. Claiming to meet the challenge for semantic interoperability and to offer a sustainable pathway, the resulting documents and specifications are sometimes controversial and even inconsistent. Methods: Based on long-term experiences from national and international EHR projects, inputs from related academic groups, and active involvement at CEN, ISO, HL7, an analysis and evaluation study has been performed. Using the Generic Component Model (GCM) reference architecture, the characteristics for advanced and sustainable EHR architectures have been investigated. The dimensions of such an architectural reference model have been described, including basic principles of the underlying formal logical framework. Results: Strengths and weaknesses of the different standards, specifications, and approaches have been studied and summarized. Migration pathways for re-using and harmonizing the available materials as well as for formally defining standards development roadmaps can be derived. Conclusions: For providing interoperable and sustainable EHR systems, an EHR architecture reflecting all paradigms of the GCM is absolutely necessary. The resulting EHR solution represents a services architecture of distributed components. The development process shall be completely model-driven and tool-based with formalized specifications of all domains’ aspects.

And Control

Within the information systems field, reference models have been known for many years. A reference model is a conceptual framework and may be used as a blueprint for information systems development. Despite the relevance of reference model quality, little research has been undertaken on their systematical analysis and evaluation. In this chapter, we describe how reference models can be analyzed from an ontological point of view. Such an analysis consists of four steps: 1) developing a transformation mapping, 2) identifying ontological modeling deficiencies, 3) transforming the reference model, and 4) assessing the results. The usefulness of our method will be demonstrated by analyzing Scheer’s reference model for production planning and control. Although our approach is based on sound theory, we argue that this approach is not inherently superior to other approaches of reference model analysis and evaluation.

During the last two decades a lot of methodology research has been conducted for the design of software user interfaces (Kirisci, Thoben 2009). Despite the numerous contributions in this area, comparatively few efforts have been dedicated to the advancement of methods for the design of context-aware mobile platforms, such as wearable computing systems. This chapter investigates the role of context, particularly in future industrial environments, and elaborates how context can be incorporated in a design method in order to support the design process of wearable computing systems. The chapter is initiated by an overview of basic research in the area of context-aware mobile computing. The aim is to identify the main context elements which have an impact upon the technical properties of a wearable computing system. Therefore, we describe a systematic and quantitative study of the advantages of context recognition, specifically task tracking, for a wearable maintenance assistance system. Based upon the experiences from this study, a context reference model is proposed, which can be considered supportive for the design of wearable computing systems in industrial settings, thus goes beyond existing context models, e.g. for context-aware mobile computing. The final part of this chapter discusses the benefits of applying model-based approaches during the early design stages of wearable computing systems. Existing design methods in the area of wearable computing are critically examined and their shortcomings highlighted. Based upon the context reference model, a design approach is proposed through the realization of a model-driven software tool which supports the design process of a wearable computing system while taking advantage of concise experience manifested in a well-defined context model.

This chapter deals with a roadmap on the bidirectional interaction and support between knowledge discovery (Kd) processes and ontology engineering (Onto) mainly directed to provide refined models using common methodologies. This approach provides a holistic literature review required for the further definition of a comprehensive framework and an associated meta-methodology (Kd4onto4dm) based on the existing theories, paradigms, and practices regarding knowledge discovery and ontology engineering as well as closely related areas such as knowledge engineering, machine/ontology learning, standardization issues and architectural models. The suggested framework may adhere to the Iso-reference model for open distributed processing and Omg-model-driven architecture, and associated dedicated software architectures should be defined.

Summary Objectives: Forming the informational reflection of the patients and their care, the Electronic Health Record (EHR) is the core application of any complex health information system or health network. Such an ideally lifelong history file must be reliable, flexible, adaptable to new concepts and technologies, and robust, to allow for sharing knowledge over its lifetime. A sophisticated architecture must be chosen for meeting this challenge. Methods: An advanced EHR architecture for designing and implementing future-proof EHR systems must be a model of generic properties required for any Electronic Patient Record to provide communicable, comprehensive, useful, effective, and legally binding records that preserve their integrity over the time, independent of platforms and systems as well as of national special-ties. The resulting approach is based on the ISO Reference Model – Open Distributed Processing. Results: Based on advanced architectural principles introduced in the paper, a new generation of EHR systems has been designed and implemented for demonstrating the feasibility of the approach. This result is presented and evaluated regarding the achievements and problems using the component-based paradigm of model-driven health information system architectures. Conclusions: The future-proof EHR approach that has been established has been shortly evaluated. Advantages regarding flexibility, reliability, and portability of policy-driven, highly secure, role-dependent applications have to be considered in the light of performance as well as of the availability of network and application services.

This paper presents a process, a method and a framework for developing families of software systems in a domain. The process is generic (domain-independent) and produces skeleton software architectures as Software Product Lines. The genericity is supported by the metamodels (abstract languages) that are defined in order to describe the Reference Architecture (structure view, behavior view and variability view) of the system domain. A standardized Production Plan takes the Reference Architecture as input and produces the equivalent Skeleton Software Architecture (component-connector view) using a Feature Model configuration (describing the system to be) as output. This Skeleton Software Architecture includes the structure and behavior of the target software product. A framework has been implemented to support the approach. The process is applied, as an example, to the Diagnostic Expert Systems domain. Our approach is based on Model-Driven Engineering techniques and the Software Product Line paradigm. A domain analysis must be done in order to build the Reference Architecture.

Smart grid is a new revolution in the energy sector in which the aging utility grid will be replaced with a grid that supports two-way communication between customers and the utility company. There are two popular smart-grid reference architectures. NIST (National Institute for Standards and Technology) has drafted a reference architecture in which seven domains and actors have been identified. The second reference architecture is elaborated by ETSI (European Telecommunications Standards Institute), which is an extension of the NIST model where a new domain named distributed energy resources has been added. This chapter aims at identifying the use of IoT and IoT-enabled technologies in the design of a secure smart grid using the ETSI reference model. Based on the discussion and analysis in the chapter, the authors offer two collaborative and development frameworks. One framework draws parallels' between IoT and smart grids and the second one between smart grids and edge computing. These frameworks can be used to broaden collaboration between the stakeholders and identify research gaps.

This paper focuses on the implementation of the concept of microservices, which can be used to design and implement distributed edge services for IoT applications. Basically, IoT is a platform where integrat-ed services are connected to a common network, so all devices are able to collect and exchange data with each other. Typically, monolithic user mobility services are developed for the core components of the ETSI MEC Unified Systems Reference Architecture. The ETSI MEC views microservices as a tool for separating monolithic applications into a set of loosely coupled distributed components, i.e. which provides an independent unit that implements a function. This architecture is expected to facilitate dynamic adaptation at runtime. However, increased modularity can also increase the load on orchestration and system management. In MEC, user equipment is connected through gate-ways to microservices running at the edge node. In the work, a distributed service is implemented using Docker containers and is designed to actually adapt to surrounding low-capacity servers. The results demonstrate that low latency for edge applications can be achieved with this kind of implementation. The integration of software technology with a standardized boundary system provides a solid foundation for subsequent development. This article discusses the use of edge computing architecture and Kubernetes for orchestration and management of network applications.

Abstract: This work is an altimetry evaluation study involving Digital Elevation Models ASTER GDEM version 2 and SRTM version 3. Both models are readily available free of charge, however as they are built from different remote sensing methods it is also expected that they present different data qualities. LIDAR data with 25 cm vertical accuracy were used as reference for assessment validation. The evaluation study, carried out in urbanized area, investigated the distribution of the residuals and the relationship between the observed errors with land slope classes. Remote sensing principles, quantitative statistical methods and the Cartographic Accuracy Standard of Digital Mapping Products (PEC-PCD) were considered. The results indicated strong positive linear correlation and the existence of a functional relationship between the evaluated models and the reference model. Residuals between -4.36 m and 3.11 m grouped 47.7% of samples corresponding to ASTER GDEM and 63.7% of samples corresponding to SRTM. In both evaluated models, Root Mean Square Error values increased with increasing of land slope. Considering 1: 50,000 mapping scale the PEC-PCD classification indicated class B standard for SRTM and class C for ASTER GDEM. In all analyzes, SRTM presented smaller altimetry errors compared to ASTER GDEM, except in areas with steep relief.

Cloud enterprise resource planning (Cloud ERP) is an internet- and cloud computing-based enterprise information system developed on the cloud platform. Cloud ERP has lower costs and shorter development time compared with traditional ERP system, but it remains in a state of information isolated island. To maximize the advantages of cloud computing and make up the deficiency of traditional ERP systems, it is necessary to break down the "wall" between enterprises, making cloud ERP enter a more open and interconnected ecological environment. The model-driven development approach contributes to a better resilient scheduling capability of ERP system, leading to faster development and deployment of it. In this article, the authors propose a “knowledge + data” model-driven open ecological cloud ERP and explain the definition and functions of each model layer. Finally, the effectiveness of model layers is demonstrated in the open ecological cloud ERP reference architecture.
