Background: Standardization is concerned with ongoing terminology standardization activities. Activities are rather complex in divergent topics and current themes of interest. The article is concerned with terminology standardization activities in Germany and international standardization activities for smart grids and smart-grid-related topics like smart metering systems, smart homes, and electromobility. Even though standardization topics are very clearly organized by standardization road maps, and responsibilities are distributed among working groups, there are still conceptual overlaps between activities of different groups that will result in inconsistencies and ambiguities in their respective glossaries. These glossaries, however, undergo only a limited process of synchronization during their development, especially on the level of single concepts and terms. The application of inconsistent and ambiguous terminology in standards may later on reduce their internal and external consistency, readability, and understandability. To create high-quality standards, conceptual consistency needs to be guaranteed. To do this, terminologies under development should be made more openly available to standardization working groups in the development phase (and not only after completion). Furthermore, additional synchronization tasks on the conceptual level are needed to generate consistent and clear conceptualizations of new technologies. Methods: A number of glossaries have been analyzed for overlaps as described by this article. Results: The article gives an overview of issues found in the respective glossaries, and the process can lead to proposals which may be put to vote among domain experts.

University Library Braunschweig (UB Braunschweig), University and State Library Darmstadt (ULB Darmstadt), TIB – Leibniz Information Centre for Technology and Natural Sciences and the Fraunhofer Information Centre for Planning and Building (Fraunhofer IRB) are jointly establishing a specialised information service (FID, "Fachinformationsdienst") for the disciplines of civil engineering, architecture and urbanism. The FID BAUdigital, which is funded by the German Research Foundation (DFG, "Deutsche Forschungsgemeinschaft"), will provide researchers working on digital design, planning and production methods in construction engineering with a joint information, networking and data exchange platform and support them with innovative services for documentation, archiving and publication in their data-based research.

Zusammenfassung: Die Interpretation des Konzepts von Industrie 4.0 ist vielschichtig und abhängig davon, ob aus der Sicht des Maschinen-oder Anlagenbaus, von der IT Branche oder von der Automatisierungstechnik an das Thema herangegangen wird. Es ist jedoch klar zu erkennen, dass die systemweit eindeutig definierte Semantik aller gemeinschaftlich genutzten Daten zwingend erforderlich ist. Ausgangspunkt der Überlegungen ist eine Gruppierung von I40-Komponenten, welche die Eigentü-mer der Daten sind. Diese sind Bestandteile von CyberPhysical-Systems (CPS), in denen sie Dienste anbieten, um zusammen mit IT-orientierten Diensten neue Wertschöpfungsketten zu bilden. Alle Dienste und Dienstinhalte müssen dafür semantisch eindeutig definiert sein. Anhand von Produkt-, Prozess-und Ressourcen-Modell (PPR-Modell) und dem Datenmodell der VDI/VDE 3682-Richtlinie wird beispielhaft dargestellt, wie die Informationen über Industrie-4.0-Komponenten semantisch eindeutig beschrieben werden können. Es wird dargestellt wie diese Beschreibung auch für die Daten der I40-Dienste verwendet werden kann. Dadurch steigt der Grad der Fä-higkeit, semantisch eindeutige Daten maschinell zu verarbeiten.Abstract: Interpretation of the concept Industry 4.0 is complex and depends very much on from which point of view the topic is approached -machinery design or plant engineering, IT or automation technology. It is clear, however, that a defined semantic for all commonly used data is mandatory. The starting point for consideration is the grouping of I40 components that are provider of the data. These components are parts of cyber physical systems, where they offer services in order to create new value chains together with IT oriented services. All services and service contents must be defined semantically unique. Based on the product-process-resourcemodel (PPR model) and the data model of VDI/VDE 3682 this contribution shows how information on I40 components may be described semantically unambiguous. It is shown how this method of description may be applied to data of I40-services. By application of this method the degree of semantically unique data is increased.
