Context of this talk

To provide an overview of the information exchange and management needs of Smart City applications, particularly of cross-domain applications, and the various standards available, in particular of the ETSI standard API called NGSI-LD from ISG CIM.

IoT Platforms such as oneM2M provide interoperability across various sensor systems and access networks, however municipal and commercial applications in Smart Cities need to exchange information between multiple platforms and data systems.

IoT & ICT Platforms are extending to fill this need.

Severe Lack of Meta-data: Provenance, Quality, Licensing

Do you label the source and measurement technique? Do you use timestamps and geospatial attributes with accuracies?Do you include a license condition? Or is it "only in the company“Do you tag personal information for faster GDPR responses?

ETSI ISG CIM Goal: Interchange Data and Context

ETSI ISG CIM has been working to create a better link or bridge between traditional IoT and database approaches and the semantic web. Promoting consensus use of SmartCity ontologies is a particular focus.

We define an API called NGSI-LD, based on JSON-LD. The underlying model has entities identified by URIs. Entities can have attributes (Properties or Relationships) which can also have attributes i.e. the model is a Property Graph.

"id": "urn:ngsi-ld:Vehicle:A4567","type": "Vehicle","brandName": {

"type": "Property","value": "Mercedes"

},"inAccident": {

"type": "Relationship","object": "urn:ngsi-ld:SmartLamppostB:Downtown1","observedAt": "2017-07-29T12:00:00","providedBy": {

"type": "Relationship","object": "urn:ngsi-ld:Org:Officer123"

} },

}

"@context": ["http://uri.etsi.org/ngsi-ld/coreContext.jsonld","http://example.org/cim/myUserTerms.jsonld"

]

• All terms are defined inside the @context links

• The unique URI of each term is sufficient to guarantee whether two applications are using the same data definitions.

Conclusions re Information Management

So many Smart City services ....

So many issues in enabling exchangeof meaninful, usable information

Do not wait for perfection ... Get started, collaborate, standardize, improve

Application

Integration of multiple Systems


The functionality of a Context Broker or Context Registry is to allow discovery and authorized access to repositories of Context Information, as well as scalable execution of Queries.
