An NGSI-LD-Based ICT Tool for Data Visualization and Traceability in Sustainable Supply Chains and Biological Resource Certification

Abstract This paper presents a novel approach to biological resource traceability and certification through an IoT-ready platform based on NGSI-LD data models. The BioReCer ICT Tool (BIT) addresses significant challenges in sustainable supply chain management by providing an interoperable, standardized framework for data collection, visualization, and verification. Our implementation leverages the Stellio Context Broker together with Apache NiFi for Internet of Things (IoT) data integration, creating a powerful platform for sustainability assessment and certification. Both the data model and the user interface have been co-developed and validated with stakeholders across four distinct case studies, demonstrating its flexibility and effectiveness across diverse bio-resource value chains. Results indicate significant improvements in data interoperability, traceability, and verification capabilities compared to traditional approaches.
