Internet of Measurement Things Architecture: Proof of Concept with Scope of Accreditation Many industries, such as manufacturing, aviation, and power generation, employ sensitive measurement devices to be calibrated by certified experts. The diversity and sophistication of measurement devices and their calibration needs require networked and automated solutions. Internet of Measurement Things (IoMT) is an architectural framework that is based on the Industrial Internet of Things for the calibration industry. This architecture involves a layered model with a cloudcentric middle layer. In this article, the realization of this conceptual architecture is described. The applicability of the IoMT architecture in the calibration industry is shown through an editor application for Scope of Accreditation. The cloud side of the implementation is deployed to Microsoft Azure. The editor itself is created as a cloud service, and IoT Hub is used to collect data from calibration laboratories. By adapting the IoMT architecture to a commonly used cloud platform, considerable progress is achieved to encompass Metrology data and serve the majority of the stakeholders.

Reference Architectures and Standards for the Internet of Things and Big Data in Smart Manufacturing This study aims to identify the main Internet of Things and big data reference architectures (RAs) available for the manufacturing industry. Besides open RAs developed by national and international consortia, proprietary RAs and frameworks are also discussed. The main building blocks of RAs are governed by viewpoints finding their root in systems and software engineering literature and standards. However, in most RAs, only technical viewpoints are addressed, and business architecture and customer context aspects are usually missing. In this paper, RAs are discussed in terms of their functionality and viewpoints addressed. Additionally, the standards developed by international and European institutions to complement RAs in the manufacturing industry are identified and presented. The RAs, standards and underlying models given can be useful for system architects, service providers, and other users as a guideline in the digital transformation of industry.
