The goal of this project was to develop the basis for a secure, unambiguous and unified exchange of data in communication networks, where metrological data is used. To address this ambitious goal the SmartCom project developed a formal framework for the transmission of metrology data based on the SI (International System of Units), which is applicable to all metrology domains in the Internet of Things (IoT). The project also developed for the first time ever a concept that summarises the minimum requirements for the use of digital calibration certificates (DCCs). Further to this the project developed online validation services for the measurement data formats involved in the DCC concept as well as a secure online conformity assessment procedure for cloud system applications for legal metrology (UniTerm). The project then demonstrated the use of its outputs via 2 demonstrators; one on the use of DCCs and the other on the use of UniTerm in order to promote their uptake by end users.

The most important impact so far is that SmartCom has initiated a worldwide discussion on how metrological information can be communicated in future IoT networks and these discussions are expected to intensify over the remaining life-time of the project. The project will enable new services based on mobile communication devices. Electronic-documentation, quality management and assurance will be supported and facilitated. Automatic processing and provision of DCC will be possible as well as automatic reading of calibration values. The project will also support the future new services based on mobile communication devices. The activities of this project will enable NMIs to take a leading role in providing quality assured metrology information to support a well-engineered Industry 4.0 and IoT ecosystem. The results of the project can be added to any standard in metrology dealing with certification or exchange of metrological data. The representatives of the consortium are active members in national and international standardisation bodies and committees and have fundamental knowledge in IT and IT‑infrastructure. This expertise enables the formulation of end-user friendly interfaces considering the essential context of the SI system and related standards and regulations. The framework of the project will be presented to a broad group of experts at an early stage of the project to enable them to design their software interfaces according to the IoT guidelines defined in this project. A significant economic benefit for all future markets involved in IoT will be realised by the adoption of uniform communication specifications, as developed by this project. This will result in shorter timespans from product to market, reduced downtimes, fewer rejected parts, improvements in quality control, better organised maintenance, better conservation of energy and resources and better business.
