The document outlines a webinar titled 'Data Models with the FIWARE Platform for the Water Sector', which took place on March 3, 2021, featuring various presenters discussing the FIWARE platform's architecture, its applications in smart solutions, and the concept of digital twins in water management. Key topics include the use of digital twins for real-time context representation, data integration across systems, and the creation of standardized data models for improved interoperability and innovation in the water sector. The event highlights FIWARE's role as a free, open-source technology that fosters collaboration and enhances data-driven decision-making.

3. The FIWARE platform /
architecture
• Fernando López – fernando.lopez@fiware.org
• Working at FIWARE Foundation, e.V. (fiware.org), a Non-Profit
organization based in Germany
• Data platforms, IoT, AI/ML, Cloud, …
• Principal Cloud Architect FIWARE Lab
• FIWARE Security Analyst
• FIWARE QA Manager
• FIWARE TSC elected member

4. FIWARE, what is it?
• Technology that is free, for all, for ever.
• A growing Ecosystem around the technology.
• A vibrant Community engaged in the success.
• A Foundation bringing support and doing for the common good.

5. FIWARE provides the basis for development
of smart solutions in multiple sectors
Smart Solutions “powered by FIWARE”
gather data from many different sources
to build a “Digital Twin representation” of the real world
(also referred as “context representation”)
which is constantly analyzed and processed in order to
automate processes or bring support to smart decisions

6. How FIWARE standards help boosting
Innovation
▪ Right-time access to relevant context data using a
standard API as the fuel for the services required.
▪ Replicability of solutions à Economies of scale à
Sustainability of investments by solution providers.
▪ Interoperability within and across domains à
Multi-side markets creation.
▪ Generating better insights by merge of data.
▪ Ability to define standard KPIs à
Benchmarking and sharing of best practices.
▪ Opportunities for Data monetization.

8. What are we referring to as Digital
Twin?
▪ Digital Twin = Digital representation of an asset
• Characterized by attributes
□ Properties
□ Relationships à Linked Data
• Values of attributes may change over time (or not)
• Typically have a location (but it is not a must requirement)
▪ (digital representation of) Context = Digital Twins Collection
▪ Cornerstone for the development of interoperable and
replicable (portable) Smart Solutions:
• Standard API for getting access to Digital Twin data (context)
• Common Data Models associated to Digital Twin classes

Data Models
https://github.com/smart-data-models
▪ Collaborating with relevant
organizations towards definition
of common data models for
multiple application domains:
• Smart Cities
• Smart Water
• Smart Energy
• …
▪ Rely on well-established de
facto standards
• schema.org
• ETSI SAREF
• IEC CIM in Energy
• UNE 178503 for Tourism
• …

13. Endorsement at global level:
Relevant standard and industry bodies
• ETSI Context Information Management API (NGSI-LD) standard.
• GSMA Reference Architecture for IoT Big Data Ecosystem with NGSI-LD
integration solution.
• TMForum supports FIWARE NGSI for real-time access to context information in
cities, collaborate in the creation of Data Marketplace platform components, and
collaborate with Smart Data Models.
• FIWARE Context Broker Technology (hence NGSI-LD) is a CEF (Connecting
Europe Facility) Building Block recommended by the EC.
• IUDX join the smart data models leading role in definition of data models for cities.
