  • 1. A  Modular  Open  Source  Pla1orm     for  Web  Scale  IoT  Interoperability   Michael  J  Koster   Open  Source  Internet  Of  Things   IoT  Toolkit  
  • 2. IoT  Web  Pla1orm  Features   •  Interoperability  –  Any  ApplicaCon  to  Any   Connected  Thing  using  Any  M2M  Protocol   •  Data  Models  drive  discovery  and  linking   •  Event  driven,  modular  applicaCon  soJware   •  Web  Programming  Model   •  Internet  and  Web  Standards   •  Web  and  Mobile  UI  hosCng  
  • 3. IoT  2.0  –  Interoperability   M2M   CoAP   M2M   MQTT   M2M   SOA   M2M   HTTP   Smart  Object  API   IoT  Toolkit   Discovery   ApplicaCons   •  Web  Objects   •  REST  +  Event  Model   •  M2M  Abstrac9ons   •  Model  Driven   Connected  Things,  Sensors,  Actuators,  Data  Sources   Models     •  Any  app  to  any  thing   via  any  M2M,  use-­‐ case  decides  M2M     •  Easy  to  deploy  new   things  and   applicaCons  using   data  models   •  Write  once,  run   anywhere  soJware   •  Network  effect   enabled  
  • 4. IoT  Interoperability   •  Ability  to  reuse  and  repurpose  resources   •  Choice  of  suitable  M2M  protocols   •  Reusable  soJware  components   •  Ease  of  integraCng  data  from  diverse  sources   •  Common  pla1orm  across  use  cases   •  Diverse  UI  pla1orms   •  Data  models  enable  machine  understanding   independent  of  M2M  protocols  
  • 5. RDF   SemanCc  and  Protocol  Interoperability   •  Separate  Control  Plane   and  Data  Plane   –  Common  Data  Models   Enable  Diverse  M2M   Protocols  Between   Smart  Objects   •  Any  Original  Catalog  or   SemanCc  Format   –  Smart  Object  stores   RDFModel  Format,   translates  others  using   a  SemanCc  Proxy   •  ApplicaCons  see  one  API   –  With  suitable  metadata   representaCon   SSN  TSB   IPSO   SemanCc  Proxy   RDF   Any  M2M   Protocol   Anywhere   Common   Data   Models   Catalogs,  Diverse  Metadata   Smart  Object  API   ApplicaCon   Smart  Object  API   ApplicaCon  
  • 6. Open  Source  IoT  Components   •  Open  Source  Components  Becoming  Available   –  IoT  Toolkit  –  REST  API  +  Data  Models  +  Events   –  Node-­‐RED  –  Graphical  ApplicaCon  Tool   –  Dojo  UI  Toolkit  –  UI  tools   –  MosquiYo  MQTT  Broker  and  Client   –  RDFlib  with  SPARQL  –  Graph  storage     –  Neo4J  Graph  Database   –  CoAP  Clients  and  Servers   •  Sufficient  to  build  a  complete  Pla1orm  Stack   •  Components  allow  ApplicaCon  soJware  to  run  in   Local  Server,  Gateway,  and  Cloud  Service  
  • 7. Model-­‐View-­‐Controller  Macro  PaYern   IoT  Feedback  Control  Loops   •  Autonomic  and   cyberneCc   feedback  loops   •  People’s   intenCons  take   part  in  the   cyberneCc   feedback  loop     Model   View   Controller   Informs   Updates   Informs   Actuates   Autonomic   Feedback   Loop   CyberneCc   Feedback   Loop  
  • 8. Model-­‐View-­‐Controller  Macro  PaYern   Mapping  to  Open  Source  SoJware  Components   •  Model   –  Object  Models,  Data  Models   –  Storage,  Discovery,  Formats,   Protocols,  Binding  to  Objects   •  Controller   –  Complex  Flow  Graphs  of   Event-­‐driven  modular  SW   –  Python  and  node.js     •  View   –  UI  Toolkit  For  ApplicaCons   –  Binding  of  UI  Components  to   Smart  Object  ProperCes   IoT  Toolkit   Node-­‐RED   Dojo  Dashboard   Node  Builder   IPSO   TSB   SSN   Catalogs  and   Repositories   Sensors,  Things,   MQTT,  CoAP,  HTTP   REST  API  +  Events   HTML5,   Mobile  Web   •  Resource  Discovery   and  Linkage   •  Builds  Smart  Object   Nodes   •  Manages,  stores  Flow   Graph  
  • 9. ApplicaCon  Development  Workflow   IPSO   TSB   SSN   Data  Models   and  Catalogs   Node  Builder   Node-­‐RED   Dashboard   Model   Controller   View   •  Discovers  Resources   •  Makes  Object  Instances   •  Builds  Applica9on   Flow  Graphs   •  UI  Construc9on
