解説
問 48
- ア
正解 The icon in the figure is the industry-standard mark called a feed icon. Its shape, with arcs spreading out from a dot like radio waves, expresses the idea that information is being distributed from that point. A website may publish a file (a feed) that gathers the titles, update times, summaries, and links of new articles in a fixed XML-based format such as RSS or Atom, and this icon is the sign that tells users such a feed is available. If a user registers the URL of the feed in an RSS reader (feed reader), the user can receive updates from many sites together without visiting each site one by one. Therefore ア, which states that the website provides data in RSS or Atom format summarizing update information, page overviews, and the like, is the correct answer.
Incorrectイ
A diary-like website operated by an individual or a group describes a blog (weblog). Blogs often publish a feed as well, but the feed icon is not a mark reserved for blogs; news sites, corporate sites, and other non-blog sites display it too. The icon itself does not indicate that the page is a blog.
Incorrectウ
Whether a page has been registered as a bookmark (favorite) in a browser is generally shown by a bookmark icon such as a star, which is something different from the feed icon. In addition, bookmarking is only a setting inside the user's own PC and browser, so it has nothing to do with whether the web page distributes a feed.
Incorrectエ
A mechanism that automatically notifies the link destination that a link to another blog has been set describes trackback (and pingback), whose purpose differs from feed distribution. Indications of trackbacks are placed in the article area of each blog and are not what the feed icon represents.
ここがポイント
- A feed (RSS / Atom) is a mechanism that gathers a site's update information and article summaries in a fixed format and distributes them. The feed icon is the standard mark showing that such a feed is offered, and subscribing with an RSS reader lets you check updates from several sites at once.
- Distinguishing confusable web terms: a blog (a diary-like site), a bookmark (registering a URL on the user side), and a trackback (notifying the link destination that a link has been set) are all concepts separate from feed distribution.
