metadata
意味: Data that provides information about other data, such as the author, date, format, or size of a file, without describing the content itself.
Metadata is often described as 'data about data.' It plays a crucial role in organising, finding, and managing information. In digital photography, metadata includes camera settings and GPS coordinates. In libraries, metadata describes books through catalogue records. The concept has gained public attention through privacy debates, as phone metadata (who called whom, when, and for how long) can reveal sensitive information even without call content.
