Automatic generation of Web of Things servients using Thing Descriptions

Similarly to the standardization effort initiated for the World Wide Web in the 1990s, the World Wide Web Consortium is currently working on the Web of Things (WoT) specification. This initiative aims to tackle current fragmentation in the so-called Internet of Things by using existing Web standards. The ultimate goal is to cope with the increasing number of devices that are being connected to the Internet and to enable interoperability among them. On the other hand, Model-Driven Engineering (MDE) approaches make use of models to raise the abstraction level with the objective of accelerating the software development process, enabling design and code reuse, and increasing software quality.This work proposes to apply MDE techniques to enable the efficient development of WoT servients. Based on the WoT Thing Description specification, this work proposes both a textual-based concrete syntax and a model-based abstract syntax—both fully compliant with the WoT specification—that enable the generation of WoT servients in C++ with CoAP communication capabilities. This proposal is implemented by a tool that covers the whole development process, which is publicly available under an open source license.
