What is OIL trying to achieve?
The current Web is entirely aimed at human readers. Machines are oblivious to the actual information content: web browsers, web servers and even search-engines do not really distinguish weather-forecasts from scientific papers, and cannot tell a personal home-page from a major corporate web site. This inability to process the contents of information by machines seriously hampers the functionality of the current Web. Computers are limited to transmit and present information on the Web, and cannot really help us in processing this information. The vision of the Semantic Web aims at creating a Web where information can be “understood” by machines as well as by humans. This of course requires that information is represented in such a way that its meaning (its “semantics”) is in a machine-accessible form. OIL is designed to be exactly such a representation of machine-accessible semantics of information on the Web.
