The Web of Things (WoT) recommendation of W3C suggests a model for integrating Things (e.g. devices) in the Web. In addition to W3C, OpenAPI specification provides a method for documenting RESTful services so that a user or another service can comprehend their purpose and reuse them in applications. This work applies the OpenAPI service description framework to Web objects (i.e. Things). As a result, OpenAPI descriptions of Web Things provide a complete documentation of the services exposed by Things and of their capabilities. The resulting descriptions can be converted to an ontology in order to allow a machine to better understand the inherent meaning of Thing descriptions and interact with them. Then, Thing descriptions exposed in the Web can be easily discovered, queried by Semantic Web query languages (e.g. SPARQL) and checked by reasoners (e.g. Pellet) for consistency or, for inferencing hidden properties. The approach is compared to the Web of Things Description (TD) model of W3C in terms of completeness of the representation.
