What does the Public Resolver toggle actually control and why should I tick and "turn it on"

Every item on GCN already has a public page anyone can reach by scanning its RFID tag or QR code — your customers know this as the Product ID page, and it stays public no matter what this toggle is set to.

Behind that page sits a second, technical layer called a resolver. Think of it as a signpost rather than a page: when something asks about a specific item, the resolver decides what to hand back depending on who's asking. A person's phone gets sent straight to the familiar Product ID page. A piece of software instead — another company's compliance system, an auditor's tool — can ask the same address for structured, computer-readable data, and gets back a technical document instead of a webpage.

This toggle controls how much of that technical data a system can retrieve — not what a person sees on the page, which never changes. When it's on, a requesting system also gets full B2B-level detail: material composition, certifications, facility details, and circular performance data.

A real, live example (SKU 100, Arcflare Workwear — a genuine test record, not a mockup): a person scanning this item's tag lands on app.globalcircularnetwork.com/resolve/E28068940000503281394D25 — a normal page showing SKU, brand, category, size/colour, REACH SVHC status, material composition, the full list of claimed certifications and evidence (Better Cotton, OEKO-TEX, bluesign, GRS, ISO 14001, SA8000, and more), facility names, and circular performance data. 

A system asking the same identifier for structured data instead gets this back:

{"linkset":[{"anchor":"https://iywuykweoudtijmnbnkd.supabase.co/functions/v1/idr/E28068940000503281394D25","dpp":[{"href":"https://app.globalcircularnetwork.com/resolve/E28068940000503281394D25","type":"application/ld+json","title":"GCN Digital Product Passport","hreflang":["en"]}]}]}

Note this particular item only has a dpp link, no dcc — that's because it's priced under the €1000 threshold for the Verified DPP feature, not a fault in the example.)

One thing that never changes regardless of this setting: any hazardous substance above the EU's legal threshold is always disclosable (REACH Article 33).

Why would I turn this on?

The EU's incoming product passport rules (ESPR) are heading toward a model where detailed technical and compliance data — not just basic consumer information — needs to be available to the people who legitimately need it: recyclers, auditors, and market surveillance authorities checking a claim. 

The exact rules for textiles specifically are still being finalized (expected around 2027, with compliance following a couple of years after), but the direction is clear. Turning this on makes that detailed data available now, ahead of that requirement landing, rather than needing to revisit this later. It doesn't change what a consumer sees on the product page either way — that stays the same regardless of this setting.
