The increasing interest in Cloud Computing solutions, has led to the proliferation of Cloud service offerings over the Internet by multiple Cloud providers. The need for efficient and accurate service discovery based on user needs has become a significant challenge. Cloud services are mainly offered by means of Web services based on the REST architecture style and need to be formally described in a way that is both understandable by humans and machines. In this work, we propose the adoption of the OpenAPI Specification (OAS), a simple and yet powerful specification for the description of REST APIs, as the description language of Cloud services. In addition, we present a set of extension properties, forming the Semantic OpenAPI Specification (SOAS), that semantically enrich the OAS service descriptions, so as to be understandable by both humans and machines. Finally, we demonstrate that is plausible to transform SOAS descriptions to ontologies as this enables application of state-of-the-art querying languages (e.g. SPARQL) for service discovery and of reasoning tools for detecting inconsistencies and inferred relationships in SOAS descriptions.
