What “metadata” means

Wiktionary · Wikipedia

metadata/ˈmɛt.əˌdeɪ.tə/

  • nounData that describes other data, serving as an informative label.
Full entry on Wiktionary →

Metadata is data that defines and describes the characteristics of other data. It often helps to describe, explain, locate, or otherwise make data easier to retrieve, use, or manage. For example, the title, author, and publication date of a book are metadata about the book. But, while a data asset is finite, its metadata is infinite.

#metadata across platforms

every network with a public tag surface

Follow #metadata straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/metadata
