IIIF

IIIF to CWorld is a browser extension for opening IIIF manifests, Internet Archive videos, and geolinks in CWorld, the Chronoscope World viewer that runs in the browser on demand. It adds a context menu item for links labeled Open IIIF book, IA video or geolink in CWorld. The page describes it as a Chrome and Firefox extension.

The extension presents IIIF manifests and Internet Archive videos as thumbnails. Its context menu applies to links that can be imported with Smart Drag’n’Drop. Listed use cases include opening any IIIF manifest link, opening search result items from libraries that support Smart Drag’n’Drop, opening books and videos from the Internet Archive, opening permalinks shared on Mastodon or Bluesky, and opening geo links on Wikipedia pages so Chronoscope World loads at the referenced coordinates. The page also notes that IIIF is a web format for library collections such as old books, newspapers, maps, photos, and paintings.

For delivery, the page offers a Firefox Mozilla add-on and a pre-release for Chrome-like browsers. It says the extension is not yet distributed via the Web Store and provides manual installation steps for Chrome or Brave by downloading a ZIP file, extracting it, enabling Developer Mode, and loading the unpacked extension folder. The page also records an MIT License, and attributes the extension to Matthias Müller-Prove.
