From a GTIN, Central checks fill power, fill weight, waterproof rating (mm), breathability (RET), weight in grams, season / temperature rating, recycled content, and Fair Trade certification — with sources attached.
They're built on the numbers buyers compare side-by-side. Fill power and fill weight, waterproof rating in mm, breathability (RET), weight in grams, season / temperature rating, recycled content, Fair Trade, bluesign.
Your supplier row has title, GTIN, brand, and a color. Every technical column is empty, vague, or sourced from a marketing bullet that drops the unit.

The data outdoor buyers, marketplaces, Google, and AI shopping agents all rely on. Each field comes back with the source, confidence, and review state attached — no rounding, no invention.
Each job ships a verified output, not a draft. Sources attached, confidence per fact, marketing hype refused.
Stop publishing "warm down jacket". Central pins fill power (du) and fill weight (g) to the verified use range — down or synthetic, sleeping bag EN 13537 / ISO 23537 rating, jacket comfort window.
"Waterproof" isn't a field. 20,000 mm hydrostatic head is. Central distinguishes a true membrane rating from a DWR-only finish, with the test standard cited.
Outdoor buyers compare gram-for-gram. Central reads the brand spec sheet, supplier sheet, and product page — then reconciles them into one verified weight per size, with packed dimensions attached.
Fair Trade Certified. bluesign approved. RDS. 100% recycled. Central matches each claim to the issuer's certificate number — or marks it for review when the source is only a marketing page.
Sleeping bags EN 13537 / ISO 23537. Ski bindings FIS. Tents 3-season / 4-season. Central attaches the standard, the comfort / limit values, and the test report — not a vibes-based "warm".
"Ultralight." "Ultra-warm." "Bombproof waterproof." "All-mountain." Held, narrowed, or removed until the record can prove them with a gram, a millimeter, or a test standard.
The same Patagonia Down Sweater Hoody. Sparse supplier import on the left. The Central record on the right — grouped by category, every fact cited, every hype claim held.
The same Down Sweater Hoody record adapts into Google Merchant Center fields, ChatGPT Shopping JSON, and a Bergfreunde custom feed — each tuned to its destination's character limits and field rules.

Central treats the brand's published spec as the anchor (0.99+ when the brand states it), then cross-checks against retailer pages, RDS certificate data, and product reviews. A 2-source agreement at the same du and g grade gives a publishable confidence; a 5-source agreement gives 0.97+. If sources disagree, the value is held until a merchant decision lands — not averaged into a marketing number.
Sleeping bags get the comfort, limit, and extreme values from the standard attached to the verified record — with the test report year and issuing lab when available. Central does not publish a generic "−5°C bag"; it publishes EN 13537 · 2012 · comfort −5°C · limit −12°C and lets the channel decide how to render that.
Fair Trade, bluesign, RDS, Global Traceable Down, recycled content percentages, and PFC-free DWR are matched to the issuer's certificate or the brand's audited material declaration. Marketing language like "eco-friendly" or "sustainably made" stays held until a specific cert or percentage is sourced — never published as a standalone claim.
Central reads the brand's size chart, supplier sheet, and historical returns data to produce one canonical size table per product with EU / US / UK / Japan equivalents, chest / waist / hip / inseam measurements, and a fit note (slim · regular · relaxed). Helmet-compatible hoods and gender-specific lasts are tagged where the brand supports them.
Native: Google Merchant Center, Bing Merchant Center, ChatGPT Shopping, Perplexity Shopping. Any other destination (Amazon, Bergfreunde, REI, Snow+Rock, Sport-Tiedje, Shopify metafields) is custom-feed-ready — the verified record adapts into CSV, XML, or JSON with channel-specific field shapes and character limits.
