A small workshop in the north-west of Ireland knits jumpers and scarves from undyed wool and sells them in its own shop, at markets and online. Customers want to know what a jumper is made of and how to look after it; some, years later, want to know who can mend it.
A label that answers
Each design is registered as a product with a GTIN. The sewn-in label carries a GS1 Digital Link code that opens the jumper's passport: fibre composition, care, where it was made, and a link to the repair service.
The textile template
QRiva's textile template starts from the Textile Labelling Regulation (EU) No 1007/2011: the fibre composition, by name and percentage, as the physical label already states it. The passport repeats the label; it doesn't replace it.
The ESPR passport for textiles is still waiting for its delegated act, so everything beyond the fibre composition is voluntary today. The workshop fills it in because its customers ask, not because a date says so.
One yarn lot, one notice
Undyed wool varies from lot to lot. A passport can be registered for a single batch (GS1 AI 10), so a note about one lot's shade shows only on the jumpers knitted from it, and every other jumper keeps showing the normal passport.
Mending, not replacing
The repair service is a hosted page with a short form and the workshop's address. When the repair prices or the opening hours change, the page changes, and the labels already sewn into jumpers keep working.
Every version kept
When the care advice or the documents change, the passport is published as a new version with a SHA-256 fingerprint. A jumper bought years ago still shows today's passport, and the history shows what it said when it was sold.
