48. IoT Agent Gateways Using the IOTA Tangle for Secure Data Transfer

  Chapter:    Difficulty:  ★ ★ ★ ★ 

  • Review of IoT Agent Transport Binding Architectures:
    • HTTP, MQTT, LoRaWAN, OPC-UA, ROS2 etc.
  • What is the IOTA Tangle?
    • Potential Use Cases with FIWARE.
    • Anti-Patterns.
  • Deep Dive: Creating a FIWARE-IOTA Binding :
    • Sensor Measurements (Northbound)
    • Actuation Commands (Southbound)
    • Actuation Command Acknowledgements (Northbound)
    • Gateway Bindings (Northbound + Southbound)
  • Architectural Paradigms for Novel Data Transports

Within the FIWARE Ecosystem, IoT Agents are used to ensure that devices can send their data to, and be managed from a Context Broker using their own native protocols. There is no restrictions on the transport layer to be used for these communications, it could be anything from HTTP to MQTT to OPC-UA to LoRaWAN and more.

For example, IOTA is an open-source data communication protocol and zero-fee micro-transaction system utilising distributed ledger technology. This allows participants in the IOTA network (“the Tangle”) to securely and immutably encrypt, transfer and store data.

The aim of this webinar is to demonstrate how create a gateway component for an IoT Agent and how connect to devices securely using the IOTA Tangle, using it as a single source of truth and trust in data. Additionally discussing how to pick the most appropriate transport for your use case and avoiding anti-patterns when securing IoT data.

49. Local Expert in B2B Data Sharing

  Chapter:    Difficulty:  ★ ★ ★

  • What is an LEBDS? Background and History
  • The role of FIWARE and iSHARE within Data Spaces
  • The role of the Examiners, Marking and Grading
  • Mock Examination
    • Body of Work
    • NGSI Interfaces
    • FIWARE Catalogue
    • FIWARE Ready Devices
    • Architectural Scenario
  • Conclusions and Opportunities for Local Experts in B2B Data Sharing

Effective B2B Data Sharing relies on the agreement to use common frameworks and protocols. No new frameworks and protocols should need to be built when existing technologies such as FIWARE are readily available and in common use. The fundamental technologies underpinning the process of data sharing are the use of a common trustworthy security framework identifying participants and roles and a common structured definition of payloads and protocols to be used when transferring data between trusted parties. A Local Expert in B2B Data Sharing should be able to explain the need for such frameworks and deeply understand how they operate and how the network of trust and interoperability is created.

The webinar explains the role and background required for a LEBDS and provides a walkthrough of the certification process and explains how it is run and how to study to take the exam.

50. Building Real-time Inference AI Services with FIWARE

  Chapter:    Difficulty:  ★ ★ ★ ★ 

  • Real-time inference
  • Managing and exchanging real-time data with the Context Broker
  • Training an ML model with historical data
  • Creating a Python ML package
  • Serving an ML model via REST API with FastAPI
  • Implementing an end-to-end real-time inference AI service

There is no point in training Machine Learning models if there is no plan to make them available for applications to use. In this webinar, we are going to learn how to deploy an ML model as a REST API and leverage FIWARE components to enable real-time AI inference. The use case covered involves getting data from different sources/organizations for real-time inference with a trained ML model.

This webinar is your chance to learn the end-to-end implementation of the real-time inference AI service: ML Training, Docker setup, creating a Python Package, and implementing the ML API.

51. Actuation, Federation and Interoperability of Context Brokers
