Overview
Readable ONIX XML: collapsible tree, product summaries, inline EDItEUR code-list labels and automatic validation.
ONIX Viewer turns raw ONIX XML into a readable, collapsible tree inside Chrome. Instead of a wall of tags you get syntax highlighting, one-line product summaries and every EDItEUR code list resolved in place. Features • Collapsible, syntax-highlighted XML tree • Automatic validation against the bundled ONIX 3.0 and 3.1 content models: missing or misplaced elements, codes that aren't in their EDItEUR list (including the lists a sibling selects, such as accessibility details, cover colours and hazard warnings), codes and elements EDItEUR has deprecated (naming the replacement), ISBN-13 / GTIN-13 / ISBN-10 check digits, and values that break their datatype — each pinned to the row it concerns, with a jump-to-row list • Read and copy the other dialect: one switch shows a short-tag file under reference names, or the reverse, and the copy follows what you see • <Product> blocks fold to a one-line summary (ISBN · form · title), so two presses of Collapse make a 10,000-product feed scannable • Code-list labels (ProductIDType, ProductForm, ContributorRole, LanguageCode, CountryCode, …) shown beside every value • One-click popup listing every entry of a code list, linked to the EDItEUR definition page — all 165 lists bundled • Expand and Collapse a level at a time, search, soft-wrap toggle, and Copy node XML for any subtree • Detects ONIX 2.1, 3.0 and 3.1 in both reference and short-tag dialects, plus the ONIX Acknowledgement message • Leaves non-ONIX XML (RSS, SOAP, generic XML) to the browser's native viewer Works on remote URLs and on local .xml files (enable "Allow access to file URLs" under chrome://extensions → Details). ONIX for Books and its code lists are developed and maintained by EDItEUR (https://www.editeur.org/8/ONIX/), which holds the copyright and makes them freely available. ONIX Viewer bundles the published code lists for offline lookup. It is an independent tool, not affiliated with or endorsed by EDItEUR.
