IPA IP 2022 Question 61
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問61, translated into English. ITPEC is based on the same exams.
Which of the following is a technique for creating one (1) new piece of content by combining publicly available Web pages and Web services, such as embedding and displaying map information provided by another Web service within the campus guide Web page of a university?
Explanation
Mashup — combining public Web pages and Web services, such as another service's map placed in a campus guide page, into one new piece of content.
A mashup takes data or functions that other sites publish, usually through their Web APIs, and puts them together in a page or service of its own. The campus guide does not draw its own maps: it calls a map service and shows the result inside its page, beside its own information on buildings and rooms. Reusing what already exists in this way gives a new service quickly and cheaply.
Answer (d)
Why not others:
- •(a) Single sign-on — one authentication gives access to several systems or services; it is about logging in, not about combining content
- •(b) Digital forensics — collecting and analysing electronic records as evidence after an incident or crime
- •(c) Token — a device or piece of data that proves identity or rights, such as the generator of a one-time password
Key rule: A mashup builds something new by combining existing public Web services and their APIs, rather than developing every function itself.
