Information that describes other data
Information that tells you about other data, for example when it was made, where it is from, or how it is stored.
用法パターン：
[someone] uses metadata about [something]
よくある間違い：
Learners sometimes confuse ‘metadata’ with the main information itself. Metadata is information ABOUT other data, not the data’s content. Another mistake is treating ‘metadata’ as countable (e.g., saying ‘metadatas’). In normal use, ‘metadata’ is uncountable: we say ‘some metadata’, ‘a piece of metadata’, or ‘metadata fields’.
類義語

|
data attributes (Common in databases and programming; stresses specific properties stored about the data.)
|
data about data (Informal explanatory phrase, often used to define ‘metadata’ rather than as a replacement in expert writing.)
対義語
content (‘Content’ is the main data itself (text, image, audio, etc.), not the information that describes it.)
|
