WoT Arduino
https://github.com/w3c/wot-arduino
Organization
W3C/ERCIM
Platform, Language
C++ open source project for the Arduino family of boards, and for a gateway for POSIX based systems, for example, Linux on a Raspberry Pi, and OS X for demos on a MacBook Pro. They are intended to provide proof of concept implementations for Web of Things proxy chains with cross protocol support.
License
MIT
Description
The Arduino project will support JSON thing descriptions using a binary encoding over TCP for the Arduino Ethernet Shield and the use of DHCP and mDNS for discovery of gateways. I’ve implemented a compact network driver over the SPI bus. I also plan to support the ESP8266 with its integrated WiFi hardware.
The associated gateway is designed to support multiple protocols including TCP, CoAP, HTTP and WebSockets. I am currently working on the CoAP support having already integrated support for HTTP and Web Sockets. Future plans include support for web browser based management of installed application sketches. I will publish a port of the CoAP support to the Arduino as a separate project.
These projects are work in progress, and at a very early stage of maturity.

Description
ub.js is a prototype which is designed to demonstrate the use of CSS with WoT devices. It has been implemented in several test scenarios but has yet to have any real large scale deployments. As a concept, it is well formed and with a little work should make it possible to make devices as a part of the Web, rather than something the Web connects to.

Sentilo is an open source sensor and actuator platform designed to fit in the Smart City architecture of any city who looks for openness and easy interoperability. Its objective is to exploit the information "generated by the city" and the layer of sensors deployed across the city to collect and broadcast this information.
In order to avoid vertical solutions, Sentilo is designed as a cross platorm with the objective of sharing information between heterogeneous systems and to easily integrate legacy applications.
Sentilo has been deployed on a city level in Barcelona, Spain.

Arduino RDF Server
https://github.com/ucbl/arduinoRdfServer
Organization
LIRIS lab, Lyon, France
Platform, Language
Arduino UNO (with Ethernet shield), C++
License
Creative Commons 4.0 BY SA
Description
This is a POC to embed both semantic and RESTful technologies into constrained things, while being energy-efficient, generic, discoverable and reconfigurable.
What it does: (1) expose the capabilities of its sensors and actuators using Hydra descriptions, (2) respond to JSON-LD requests to these devices, (3) handle reconfiguration requests, and (4) be shut down and restarted without losing its configuration.
How it works: it makes efficient use of available storage areas (EEPROM, program memory, RAM). It relies on several cache levels to split CoAP blocks containing RDF graphs into parts, and hence process requests and generate responses on-the-fly.
Extension: A proxy is provided to translate HTTP to CoAP and vice-versa; it can be extended to handle concerns such as content negotiation, caching or security.
