Enabling the IoT ecosystem

4. Data interoperability & IoT hubs
Data hubs
provide economies of scale and uniform access to data
lower the barrier to participation, avoid silos and foster innovation
Key challenges
Interoperation between hubs
Resource discovery and access (what data does this hub have? how do I get it? what other hubs are there?)
Hypercat is a specification which allows these questions to be answered

5. Hypercat HyperCat is a file format and a common web API
It has a small set of mandatory core metadata
horizontal
can link to domain-specific vertical vocabularies (ontologies)
It exists at application layer (OSI Layer 7)
It uses well-understood web technologies (REST, JSON)
It is publically available and unencumbered
A machine-readable catalogue for IoT data
Status: British Standards Institute PAS (Publically available specification)

6. Interoperability
“Interoperability is essential to unlock 40% of the $11 trillion potential value of the IoT”
(McKinsey)
“The internet of things: Mapping the value beyond the hype”, June 2015, McKinsey Global Institute, Copyright (c) 2015 McKinsey & Company.

7. CityVerve Manchester, UK: 2.8m people, £42 billion GVA

8. CityVerve €20m collaborative R&D project, with UK govt investing €15m
Large-scale deployment of IOT
Delivers Smart City networks, platforms and infrastructure and demonstrators
Health, Transport, Energy & Environment application areas
Several thousand data feeds across multiple platforms
Central to this will be BT’s data hub, interoperating via Hypercat with a range of other platforms

9. Semantic Technology
AIOTI (WG3), IEEE, oneM2M and W3C: Joint White Paper on Semantic Interoperability for the Internet of Things (IoT)
“The full value potential can only be unlocked if … ad-hoc, cross-domain systems of IoT are able to establish conversations and build understanding”
Using semantic technology to provide machine-processable, shared vocabularies to increase automated reasoning
Hypercat – lightweight, common, domain-independent
Next step – richer descriptions, link to domain-specific vocabularies, re-use wherever possible
