Abstract: The short course aims to provide the foundation for understanding NGSI-LD Context Broker(s). The course will begin with a brief introduction to JSON-LD (JSON Linked Data) since it is the data format used by NGSI-LD. Next, there will be a brief mention of the history of NGSI-LD and who are the organizations that are currently using it. After that, the key components and aspects of an NGSI-LD Context Broker will be described. Specifically:
· NGSI-LD Tenant and Scope
· NGSI-LD Entity, Attributes and SubAttributes
· The @context field(s) – related to JSON-LD
· The possible formats and modes of presentation of a JSON-LD (e.g., normalized)
· The API exposed by an NGSI-LD Context Broker
· As an NGSI-LD Context Broker allows querying entities by filtering them for different attributes
· NGSI-LD Subscription
· Key Differences between NGSIv2 and NGSI-LD
· Short Demo about NGSI-LD Subscriptions
Lecturer Short CV: Antonio is a Senior researcher and Project Manager at Engineering Ingegneria Informatica S.p.A. He is an expert in ICTs with special skills in areas like Open & eGovernment, Social Innovation, Smart City, Data Protection and Privacy-preserving technologies, Cloud Computing, Architectural Design, Policy making. He has been involved in several European and Italian research projects dealing with several domains (public service for PA, smart mobility, smart environment, energy, FIWARE architecture) as project manager, technical designer, work package and task leader. At present, he is the Project Coordinator of DECIDO project (H202-SC6-GOVERNANCE-2020), he is also involved in SPOTTED project (CEF-TC-2020-2 Public Open Data 2021-2024) and TEMA project (HORIZON-CL4-2022-DATA-01-01) as technical leader.
Lecturer Short CV: Matteo, a Researcher and Project Manager at Engineering Ingegneria Informatica S.p.A, possesses extensive expertise in ICTs particularly in domains such as Data Management System, GeoSpatial Data, Open-Source Architectural Design and Cloud Computing. Graduated in 2021 with a degree in Computer Engineering from the University of Salento in Lecce, his involvement spans European and Italian research initiatives covering the Water-Data Management System, Digital Twin and Emergency Event Management. In these projects, his main role was as technical coordinator, identifying technical architectures and developing the components. Most architectural blocks are mapped with open-source tools, very often compliant with the FIWARE world (NGSI Context Broker, Digital Enabler and others). He currently plays the role of technical coordinator in the European projects WATERVERSE and PathoCERT, and the role of technical/architectural support in the Italian project GAIA.
