We present SASCHA, a web browser-based application for authoring semantic Web Service descriptions by the SAWSDL standard. Even though it was conceived in a specific real domain scenario, i.e. the Italian framework for service interoperability, it is in fact a general-purpose SAWSDL tool that showcases a singular feature set including, but not limited to, simplicity of use, availability as an infrastructural service and XML Schema support. Although upper-level ontologies are expected to be stored in an ad-hoc repository, SASCHA allows for OWL ontologies being stored anywhere locally or on the web.(1)
