Abstract

The Industrial Internet of Things (IIoT) faces a fragmentation of interfaces along information modeling formats, communication protocols and service interfaces. This increasingly hinders interoperability and changeability in the IIoT. To overcome this challenge, we propose a technology-independent common core for information modeling in the IIoT. It consists of a minimal type system for literal data values, an addressing and identification scheme based on Uniform Resource Identifiers (URI), the use of both key-value associations and relational references to combine resource-oriented and semantic information modeling, and a set of core relational predicates for object-oriented information modeling. Exemplary mappings of popular IIoT information modeling formats are provided to demonstrate the generality and representational power of the proposed common core.

Zusammenfassung

Das Industrielle Internet der Dinge (IIoT) steht vor der Herausforderung einer Fragmentation der Schnittstellen bestehend aus Formaten zur Informationsmodellelierung, Kommunikationsprotokollen und Service-Definitionen. Dieser Umstand verhindert zunehmend die Interoperabilität und Anpassbarkeit von heterogenen IIoT-Anwendungen. Um dieser Herausforderung zu begegnen wird eine gemeinsame Basis für die Informationsmodellierung im IIoT als kleinster gemeinsamer Nenner gängiger Mechanismen vorgeschlagen. Anhand von praktischen Beispielen wird die Generalität und Mächtigkeit des Ansatzes gezeigt.
