VICINITY - vision and Objectives

4

VICINTY’s vision is to

  • provide “Interoperability” as a service
  • create a platform for domain-crossing, value-added

services by building and demonstrating a

  • bottom-up ecosystem of decentralised

interoperability of IoT infrastructures called virtual neighbourhood,

  • like social network for things, enabling value added

services

  • where users can share the access to their smart objects without

losing the control over them

  • where x-domain services and buisiness models can be

established

WoT evolution

13

  • Done
  • Remove
  • Physical thing, Virtual thing, Relative endpoint, Thing

description ecosystem (VICINITY concept),

  • Rename
  • Data schema (data format), Link (endpoint),
  • Add
  • Security (not described yet)
  • Changed model
  • Default value (Property  DataSchema), Media type (concept

 datatype), added cardinalities

  • Next steps: Currently discussing
  • Need of communication protocol?
  • Model types?
  • Coupling IG JSON model with ontology conceptual model?
  • Rename properties?
  • Not following OE good practices vs space reducing in TD?
  • Security
