Join and fire walk with us to unravel the secrets of how a world made of Digital Twins living in the cloud-to-edge continuum can be implemented with FIWARE components, relying on the NGSI-LD standard, and get insight into real Digital Twin use cases. Digital Twins enable system integration at multiple levels and are a core FIWARE concept. Participants will be able to see how an NGSI-LD based Digital Twin system can get its capabilities incrementally increased. The status and the roadmap of NGSI-LD in ETSI ISG CIM will be presented, including work on recent additions for operations in distributed deployments, how Asset Administration Shell (AAS) concepts from Industry 4.0 or Linked Data Event Stream functions can be supported. Participants will discover also how to connect Digital Twins using Linked Open Data compliant with the FIWARE Smart Data Models. It includes a scenario for harvesting data from external sources, making them FIWARE compatible, and publishing them as LOD in Open Data Portals. With Digital Twins, system integration becomes a breeze, and in this session, you will also learn how different frameworks bring an overlay on top of an NGSI-LD based environment to empower non-IT specialists. Also how recipes for easy deployment and operation of FIWARE systems managing digital twin data end to end can help creation of solutions based on this paradigm. Deel deep into the secrets of how to unleash the full potential of FIWARE, the standard-based open source framework of reference for development and integration of systems using digital twins!
