There are one or more pre-parsers for extracting one or more components from integrated document in a network system comprised of at least one terminal, a server, and at least one repeater, where the pre-parsers are installed in one or more of the terminal, the server, and the repeater. The server may create a primary SADL integrated document and transmit it to the terminal or the repeater. And, the repeater may transmit secondary SADL integrated document or the application, created by applying delivery context to the primary SADL integrated document to the terminal. The terminal may also apply delivery context to the primary SADL integrated document or the secondary SADL integrated document, thereby creating an application optimized for the terminal.
