- ZeitschriftenartikelA Terminology Service Supporting Semantic Annotation, Integration, Discovery and Analysis of Interdisciplinary Research Data(Datenbank-Spektrum: Vol. 16, No. 3, 2016) Karam, Naouel; Müller-Birn, Claudia; Gleisberg, Maren; Fichtmüller, David; Tolksdorf, Robert; Güntsch, AntonResearch has become more data-intensive over the last few decades. Sharing research data is often a challenge, especially for interdisciplinary collaborative projects. One primary goal of a research infrastructure for data management should be to enable efficient data discovery and integration of heterogeneous data. In order to enable such interoperability, a lot of effort has been undertaken by scientists to develop standards and characterize their domain knowledge in the form of taxonomies and formal ontologies. However, these knowledge models are often disconnected and distributed. The work presented here provides a promising approach for integrating and harmonizing terminological resources to serve as a backbone for a platform. The component developed, called the GFBio Terminology Service, acts as a semantic platform for access, development and reasoning over internally and externally maintained terminological resources within the biological and environmental domain. We highlight the utility of the Terminology Service by practical use cases of semantically enhanced components. We show how the Terminology Service enables applications to add meaning to their data by giving access to the knowledge that can be derived from the terminologies and data annotated by them.
- ZeitschriftenartikelDesign of a microgrid local energy market on a blockchain-based information system(it - Information Technology: Vol. 61, No. 2-3, 2019) Kirpes, Benedikt; Mengelkamp, Esther; Schaal, Georg; Weinhardt, ChristofIn this paper, we propose a model-based system architecture for an interoperable blockchain-based local energy market for prosumers in a residential microgrid setting. Based on the Smart Grid Architecture Model our analysis deduced 21 organizational, informational, technical and blockchain requirements for a local energy market and its underlying information system. These are evaluated in the Landau Microgrid case study. We derive, that a clear value proposition for the key stakeholders, standardization of data exchange and communication, and a suitable physical implementation are the major challenges.
- KonferenzbeitragFAPI 2.0: A High-Security Profile for OAuth and OpenID Connect(Open Identity Summit 2021, 2021) Fett, DanielA growing number of APIs, from the financial, health and other sectors, give access to highly sensitive data and resources. With the Financial-grade API (FAPI) Security Profile, the OpenID Foundation has created an interoperable and secure standard to protect such APIs. The first version of FAPI has recently become an official standard and has already been adopted by large ecosystems, such as OpenBanking UK. Meanwhile, the OpenID Foundation’s FAPI Working Group has started the work on a the second version of FAPI, putting a focus on robust interoperability, simplicity, a more structured approach to security, and improved non-repudiation. In this paper, we give an overview of the FAPI profiles, discuss the learnings from practice that influence the development of the latest version of FAPI, and show how formal security analysis helps to shape security decisions.
- KonferenzbeitragFindoo – Interoperable E-Learning Semantic Search and Content Authoring Assistance(20. Fachtagung Bildungstechnologien (DELFI), 2022) Streicher, Alexander; Schwarz, SimonSearch engine assistance systems can be of great use in the creation and curation of e-learning content. However, conventional crawling methods are typically limited in Learning Management Systems (LMS) due to technical barriers such as authentication or proprietary data formats. This article presents the concept and implementation of an e-learning search engine called “Findoo” based on a Learning Tools Interoperability (LTI) deep web crawler, combined with an assistance tool for content curation, e.g., restructuring of learning objects. Our concept includes robust crawling as well as assistance functions such as a semantic search and content recommendations. The system is designed with a modular architecture which makes fine-tuning to future use cases possible. Experimental technical verification results indicate that the system is well suited for domain-specific information retrieval.
- ZeitschriftenartikelDie Generation Alpha der Digital Health Innovationen – Eine Fallstudie aus der Multiple Sklerose Versorgung(HMD Praxis der Wirtschaftsinformatik: Vol. 59, No. 6, 2022) Schlieter, Hannes; Susky, Marcel; Richter, Peggy; Hickmann, Emily; Scheplitz, Tim; Burwitz, Martin; Ziemssen, TjalfDie digitale Transformation im Gesundheitswesen ermöglicht durch die Entwicklung zahlreicher neuer Technologien und Standards eine zunehmend individualisierte, bedarfsgerechte und berufsgruppenübergreifende Versorgung von Patienten. Diese neue Generation von Digital Health Innovationen – die Digital Health Generation Alpha (in Anlehnung an die korrespondierende Alterskohorte) – erfüllt Informations‑, Kommunikations- und Interoperabilitätsanforderungen entlang des gesamten Versorgungsprozesses, die aufgrund von abgegrenzten Leistungs- und Zuständigkeitsbereichen sowie Vergütungsregelungen oft eine unüberwindbare Hürde dargestellt haben. Im Beitrag werden mit der i) Pfadorientierung, ii) Patientenorientierung und -einbeziehung, iii) Qualitätsorientierung und iv) Integrationsfähigkeit vier zentrale Gestaltungsdimensionen von Digital Health Innovationen der Generation Alpha vorgestellt. Diese werden literaturgestützt aufgearbeitet und deren praktische Umsetzung anhand einer Fallstudie im Bereich der Versorgung von Patienten mit Multipler Sklerose aufgezeigt. Zentrale Leitfragen, konkrete Umsetzungsmaßnahmen und literaturgestützte Gestaltungsziele werden anhand eines prototypischen Vorgehensmodells beschrieben. Anhand der Fallstudie werden anschließend Implikationen für die zukünftige Digital Health Agenda abgeleitet, welche insbesondere für die Realisierung innovativer Werteversprechen und deren Integration in komplexe Zielumgebungen des Gesundheitswesens notwendig sind. Through the development of numerous new technologies and standards the digital health care transformation progressively enables an individualized, need-based, and interprofessional treatment provision. The new generation of digital health innovations—in analogy to the age cohorts, the digital health generation alpha—can therefore fulfill information, communication, and interoperability tasks along the entire care process, that previously often represented an insurmountable challenge. The four design dimensions of digital health generation alpha are introduced: i) pathway orientation, ii) patient orientation and involvement, iii) quality orientation, and iv) integration capability. These are first discussed on basis of current literature and their practical utilization is then demonstrated in a case study on patients with multiple sclerosis. A process model for pathway development is presented that incorporates the four design dimensions and transforms a treatment process into a digital, participative, and integrated care model. Central guiding questions, concrete implementation measures and literature-based design goals are described based on the process model. Finally, implications for the future digital health agenda are derived, which are particularly necessary for the realization of innovative value propositions and their integration into complex healthcare target environments.
- KonferenzbeitragIntegration of Self-Sovereign Identity into Conventional Software using Established IAM Protocols: A Survey(Open Identity Summit 2022, 2022) Kuperberg, Michael; Klemens, RobinSelf-Sovereign Identity (SSI) is an approach based on asymmetric cryptography and on decentralized, user-controlled exchange of signed assertions. Most SSI implementations are not based on hierarchic certification schemas, but rather on the peer-to-peer and distributed “web of trust” without root or intermediate CAs. As SSI is a nascent technology, the adoption of vendor-independent SSI standards into existing software landscapes is at an early stage. Conventional enterprise-grade IAM implementations and cloud-based Identity Providers rely on widely established pre-SSI standards, and both will not be replaced by SSI offerings in the next few years. The contribution of this paper is an analysis of patterns and products to bridge unmodified pre-SSI applications and conventional IAM with SSI implementations. Our analysis covers 40+ SSI implementations and major authentication protocols such as OpenID Connect and LDAP.
- TextdokumentInteroperability and Security Challenges of Industry 4.0(INFORMATIK 2017, 2017) Watson, Venesa; Tellabi, Asmaa; Sassmannahausen, Jochen; Lou, XinxinIndustrie 4.0 (I4.0) is the fourth industrial revolution, which will see the digital transformation of manufacturing, through the integration on Industrial Internet of Things (IIoT), Data and Services, and the convergence of Information Technology (IT) and Operational Technology (OT). With any such transformation, there exists challenges that must first be addressed for a successful outcome. For I4.0, these are interoperability and security, which respectively arise from the interconnection of devices from different manufacturers and/or with different communication protocols; and the interconnection of networks with competing critical and non-critical traffic, and the increased access to initially isolated networks. This paper presents an overview of standards, such as IEC 62443, the ISO 27000 series, IEC 62541 Open Connectivity Unified Architecture (OPC UA) and Time Sensitive Networks (TSN) (IEEE 1722-2016), which addresses these challenges.
- ZeitschriftenartikelInteroperability – Technical or economic challenge?(it - Information Technology: Vol. 61, No. 5-6, 2019) Stegemann, Lars; Gersch, MartinInteroperability in healthcare is a long-standing and addressed phenomenon. In the literature, it is discussed as both the cause of an insufficiently perceived digitalization and in context with an inadequate IT-based integration in healthcare. In particular, technical and organizational aspects are highlighted from the perspective of the different involved actors to achieve sufficient interoperability. Depending on the individual case, various established international industry standards in healthcare (e. g. DICOM, HL7 or FHIR) promise simple adaptation and various application advantages. In addition to the technical view, this article assumes economic challenges as the main causes for the lack of interoperability not discussed in the forefront. The economic challenges were mentioned and sparingly discussed in few cases in the literature. This article aims to fill this gap by offering a first characterization of identified and discussed economic challenges in the literature with respect to the lack of interoperability in healthcare. Based on a systematic literature search, 14 of the original 330 articles can be identified as relevant, allowing a more economic perspective on interoperability. In this context, different economic effects will be described; this includes cost-benefit decisions by individual stakeholders under different kinds of uncertainty or balancing of known individual costs for interoperability against uncertain and skewed distributed benefits within an ecosystem. Furthermore, more sophisticated cost-benefit approaches regarding interoperability challenges can be identified, including cost-benefit ratios that shift over time, or lock-in effects resulting from CRM-motivated measures that turn (non)interoperability decisions into cost considerations for single actors. Also, self-reinforcing effects through path dependencies, including direct and indirect network effects, have an impact on single and linked interoperability decisions.
- KonferenzbeitragInvestigating the impact of demographic factors on contactless fingerprint interoperability(BIOSIG 2022, 2022) Aeddon Berti, Nasser Nasrabadi and Jeremy DawsonContactless fingerprints have continued to grow interoperability as a faster and more convenient replacement for contact fingerprints, and with covid-19 now starting to be a past event the need for hygienic alternatives has only grown after the sudden focus during the pandemic. Though, past works have shown issues with the interoperability of contactless prints from both kiosk devices and phone fingerprint collection apps. The focus of the paper is the evaluation of match performance between contact and contactless fingerprints, and the evaluation of match score bias based on skin demographics. AUC results indicate contactless match performance is as good as contact fingerprints, while phone contactless fingerprints fall short. Additionally, bias found for melanin showed specific ranges effected in both low melanin values and high melanin values.
- TextdokumentKnowledge-driven Architecture Composition(INFORMATIK 2017, 2017) Burzlaff, FabianAutomating component coupling has been around for various decades. In fact, in the last few years’ interface and component matching progress seems not to be regarded as a hot-topic in research. However, reappearing paradigms such as decentralized and flexible production scenarios are again in need for automated system coupling. This is mainly due to the increasing number of heterogeneous devices. Building upon existing component integration research, this PhD project introduces case-based reasoning techniques for formalizing integration knowledge to overcome standardization requirements. As a consequence, integration knowledge becomes reusable.
