The Ontology Explorer functionalities are subdivided between client-side and server-side. More precisely, inside the server-side, represented by a GWT Service, there is the basic structure of the application; it receives the information's requests effected by the client and then retrieves and returns such information, through Remote Procedures Call (RPC), in a proper format for the compilation in JavaScript. Regarding the client-side, instead, it manages the visualisation of the information and it is here that the benefits of AJAX are exploited, particularly thanks to the widgets furnished by GWT.
The process just described is what happens to every information's request effected from the user. ![]() Ontology Explorer Architecture |
