A Practical Framework to Turn IoT Technology Into Operational Capability published the SOA-based integration vision. Web services (SOAP) is currently one of a number of different integration services alongside web APIs (REST) for example. The emergence of IoT protocols 19 introduced a plethora of new data integration options. MQTT, XMPP, AMQ, OPC-UA, DDS and LLAP are but a few of an ever-increasing list of IoT technology that need to be integrated into existing business workflows. Spiess' vision for a scenario-based, SOA-enabled integration of the Internet of Things provides the basis for the I2OC framework that extends integration beyond web services and proposes a centralized library with integration objects for OT, IT and business application integration protocols. These library objects, in conjunction with orchestration rules, are used to construct business-focused use cases or scenarios. Figure 6 - The I2OC Smart Integration approach The smart integration is based on a central library concept that contains the integration technology for all the OT, IT and business applications required for all IoT-enabled use cases. Such a central library not o nly provides a single repository of integration services, but it addresses some of the main concerns for OT and IT stakeholders around the security and trustworthiness of the IoT infrastructure. The I2OC framework uses a Smart Integration approach that combines typical middleware integration with event stream processing, data transformation, orchestration, advanced analytics and business rules. 19 Services-based integration components are wrapped in library containers and then used as integration objects in a model-driven, visual integration workflow. These integration objects are used in a drag-and- drop user interface to construct specific integration sequences or event streams. These integration sequences are further enhanced to also provide event stream processing, orchestration and other data transformation capabilities that turns it into “smart integration”. https://www.postscapes.com/internet-of-things-protocols/ - 42 - March 2018
