D4.4 First version of Integrated Platform

This document presents the first version of the CIRCULOOS Integrated Platform, the digital backbone that enables secure, interoperable and standards-based data exchange across circular manufacturing value chains. It explains how the platform combines Orion-LD, Mintaka, Keycloak and Kong, together with custom tools such as the CSV-to-Orion Agent and the Leather Board tool, to support real-time and historical data access, secure authentication, and traceable data sharing. The report also highlights the role of the CIRCULOOS Common Data Model (CDM) and NGSI-LD in connecting tools such as GRETA, SCOPT and the Digital Twin, creating the foundation for future federated and scalable platform deployment.
