ONIX Viewer nga Maendeleo

ONIX Viewer turns raw ONIX XML into a readable, collapsible tree inside
Firefox. 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 records 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
• Large feeds open fast: products are rendered as you scroll to them
• Search that sees folded rows, keyboard shortcuts, soft wrap, dark mode,
copy of any node's XML
• Detects ONIX 2.1, 3.0 and 3.1 in both reference and short-tag dialects,
plus the ONIX Acknowledgement message

How it works

The extension acts only on pages served as XML whose content is ONIX: the
EDItEUR namespace or an ONIX root element. Every other page — HTML, JSON,
RSS, generic XML — is left exactly as Firefox shows it. Nothing is stored,
nothing is sent anywhere, and the only
network request is a re-fetch of the page you are already viewing, to read
its source. Local .xml files work too.
