  • Ben je bezig met het maken van een dataset met Linked Data aspiraties, werkt opeens VIAF niet meer naar behoren en geven ineens ook al je eerder opgeslagen (en geverifieerde) VIAF PID's een foutmelding. Hopelijk is dit een tijdelijk fenomee

  • Hey can someone tell me what's the process nowadays to tell #viaf they are linking to the wrong #wikidata item? (it's clean wikidata side now)

#viaf across platforms

every network with a public tag surface

Follow #viaf 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.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

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/viaf
