ONIX Viewer

About

ONIX Viewer turns raw ONIX XML pages into a readable view inside Chrome.
ONIX (the bibliographic-metadata format used across the publishing
industry) is normally shown as a wall of tags; this extension renders
it as a syntax-highlighted, collapsible tree with the EDItEUR code
lists wired in.
Features
  • Collapsible, syntax-highlighted XML tree
  • Search, expand-all, collapse-all, soft-wrap toggle
  • Auto-collapsed <Product> blocks with a one-line summary
    (ISBN · form · title) so a 10,000-product feed stays scannable
  • Resolved code-list labels (ProductIDType, ProductForm,
    ContributorRole, LanguageCode, CountryCode, …) inline beside
    every value
  • One-click popup showing every entry of any list (all 165
    EDItEUR lists bundled, ~4,750 codes), linked to the canonical
    EDItEUR definition page
  • ONIX 3.0 / 3.1 detection, both reference-name and short-tag
    dialects, plus older 2.1 docs
  • Leaves non-ONIX XML alone — the browser's native viewer
    handles RSS, generic XML and SOAP responses
Works on local .xml files (after enabling the per-extension toggle in
chrome://extensions → Details → Allow access to file URLs) as well as
remote URLs.
Built at Bokbasen — useful for anyone reading ONIX.
