What may be scraped may be “details” not protected by copyright. The term “display scraping” is used where the scraper program extracts the key information which can seem on the tip-users’ display show (i.e. ignoring sections of coding and merely seeking to extract plain textual content from a webpage).

The need to interface such a system to extra modern techniques is widespread. A robust resolution will typically require issues no longer available, corresponding to source code, system documentation, APIs, or programmers with expertise in a 50-12 months-old computer system. In such cases, the only possible resolution could also be to write down a display screen scraper that “pretends” to be a user at a terminal. The display screen scraper may hook up with the legacy system by way of Telnet, emulate the keystrokes wanted to navigate the old user interface, course of the resulting display output, extract the desired knowledge, and cross it on to the fashionable system.
