Abstract

The Deep Web, as the name implies, is typically hidden from a common web user, because the information it contains, is not findable through standard search engines. However, this hidden information is often useful to the web user. The question is, what are the possibilities to surface those resources? An example of Deep Web resource would be a SOAP web service of Estonian Business Registry. If a developer wants to use this service in a web application, to query data about annual reports, he should create a service client on the server-side and then manually wire together the user interface and the web service. This requires quite a lot of work and knowledge of server-side programming. Following a current trend where Web application development is geared towards the browser-side implementations, what should a developer do in order to create a client-side mashup using Deep Web resources and web widgets to visualize the annual report data? Unfortunately, his possibilities narrow down quite heavily. The creation of SOAP requests on the client-side is not well supported and he should still put up a server-side proxy to request data outside his own domain. And of course, the wiring with visual widgets still requires much work. This thesis aims to provide a solution that helps a developer to create such client-side mashups. It will provide an infrastructure, that takes care of the cross-domain request problems by creating a common server-side proxy, that anyone could use. It will allow a developer to initiate SOAP requests from within a web browser, by using just JSON request data. Additionally, the solution allows a developer to integrate SOAP web services with visual widgets, by using semantic integration instead of hard-wiring.
