Introduction

What is Smart Data Models Program:

  • Smart Data Models is a collaborative initiative to provide multisector agile standardized free and open-licensed data models based on actual use cases and adopted open standards

​

What is NOT Smart Data Models Program:

  • Another ontology.
  • Only working for NGSI standard (but it works of course)
  • An standardization body but an agile standardization program

Introduction

  • Specifications :
    • 6 languages (EN, FR, GE, SP, JA, IT)
    • Automatically generated

​

  • Technical validation:
    • Json schema
    • Single source of truth (include definitions)

​

  • Examples:
    • Required
    • Json, jsonld, geojson feature, DTDL, csv

Current Status

  • Data models: 717 official and 88 on the queue
  • Subjects: 53 in 12 domains
  • Contributors: 111 active belonging to 71 different organizations
  • Terms available: 15.400 terms defined
  • Ontologies mapped: 18 (IUDX, schema.org, SAREF, ETSI, etc)
  • Open standards: OPCUA, GTFS, GBFS, CIM Energy, DCAT-AP, EPANET, Open311, etc

Current Status

  • Last Data Models:
    • Digital Innovation Hub: Cross Sector
    • Unmanned Aerial vehicles (drones): Smart Aeronautics
    • Open Connectivity: Smart Sensoring
    • EU Proof of Vaccination (COVID19): SmartHealth
    • Waste Water Plant: Smart Water
    • Streetlight Feeder: Smart Cities

9 of 14

Differential factors

  • Open licensed: Free use, modification and sharing
  • Collaborative: Data models provides by actual users,
  • Not reinventing the wheel: Adopting existing standards OCF, GTFS, GBFS, CIM Energy, OPC UA, etc.
  • Automated: Publishing and translations (6): Once ready publication takes 15 minutes, tests can be automated
  • Mapping existing vocabularies: Schema.org, SAREF, GSMA, ETSI can be mapped for the linked data context
