IoT Toolkit Overview and links
IoT Toolkit is an open source reference implementation of the Smart Object API as described in Data Models for the Internet of Things
http://iot-datamodels.blogspot.com/
It provides a middleware layer for virtualization and integration of data from sensors, actuators, and other IoT devices and data sources. The main focus of IoT Toolkit is that it is model-driven, that is focused on resource modeling using collections semantic hyperlinks.
IoT Toolkit implements HTTP/REST, CoAP, and MQTT protocols and acts as a stateful bridge between these different protocols.

IoT Toolkit implements an event model that allows real time event and protocol handling of resource updates and state changes.

The current state of IoT Toolkit is that the SmartObject API is nearly fully implemented. Current focus is on integration of Resource Directories, models, and catalogs.

The roadmap for IoT Toolkit includes integration of application software using Node-RED and web stack IDE features to enable developers to use IoT Toolkit from within composable modular event-driven application software. The SmartObject REST API provides a stateful component that connects seamlessly to the Node-RED event model. Also in the future is a simple GUI builder to create dashboards and onscreen control surfaces for Smart Objects.
