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!

DT within the FIWARE ecosystem
❖ Context Information modeled using NGSI and FIWARE Smart Data Models
❖ GEs guaranteeing data acquisition, data processing, and data consumption

3. Vienna, 12-13 June, 2023 | #FIWARESummit www.fiware.org
Collaboration of DTs
❖ One barrier of DTs is the integration among them and with third systems
❖ A type of intermediary system is an Open Data Portal

4. Vienna, 12-13 June, 2023 | #FIWARESummit www.fiware.org
The role of the DT in the Open Data lifecycle
❖ Digital Twin as producer
➢ Sanitize data
➢ Generate metadata
➢ Publish data and metadata
❖ Digital Twin as consumer
➢ Discover LOD sources
➢ Download LOD sources
➢ Generate historic data (if they do not exist)
➢ Consume LOD

5. Vienna, 12-13 June, 2023 | #FIWARESummit www.fiware.org
Publishing LOD data from the DT
FIWARE Draco generates the metadata and publishes de metadata/data in an Open
Data Portal
Draco LOD processors:
❖ UpdateCKANMetadata:
generates metadata compliant
with CKAN
❖ NGSIToCKAN: publishes
data/metadata as LOD in a
CKAN ODP

Conclusions
❖ LOD allow the collaboration of different DTs
❖ Publishing high quality datasets eases the integration of DTs
❖ Draco processors automatizes the publication of LOD from the FIWARE
ecosystem
❖ Data can be accessed directly from the ODP or from the Context Broker
❖ DCAT-AP for metadata and NGSI-LD + FIWARE Smart Data Models for data
❖ Not valid for sensitive data
