System Architecture of the OntologyWidget. Queries from the two components of the OntologyWidget are sent to the SMD Ontology Web service (either directly, in the case of the SMD deployment, or indirectly via the servlet stub in the case of a third party deployment), and are answered with an XML Http Response, sent to the client's browser, in the case shown, via the servlet stub. The JavaScript running in the client's browser then renders the XML, either into the Ontology Browser, or by indicating potential autocomplete terms.
