Motivation

European Article Number (Q357404) is the European standard for identifying a specific product that would be sold. Is the common barcode that everyone see on each item we buy. Books already have ISBN-13 (P212) that is a subset of EAN-13. I think that we could benefit a lot with this new property in order to catalogue well every kind of retail products. There will be a lot of synergies with all the information spread on many online markets (like Amazon, Ebay, but also many many local online stores). Moreover we can finally identify precisely an item, so for example in the food domain we can collect precise accurate information about ingredients and so on (joining the linked data cloud of projects like foodrepo.org and openfoodfacts.org) AlessioMela (talk) 18:50, 15 December 2019 (UTC)[reply]

Question @AlessioMela: Am I correct in thinking that every time there is a packaging revision this leads to a new EAN-13, to allow retailers and wholesalers to distinguish this year's version from last year's? If so, it might be only quite a narrow range of items that could be securely identified by only a single EAN-13. Is that something that should worry us?

@Jheald: you're correct. I think is the same as is now for books with ISBN-13 (P212). --AlessioMela (talk) 10:28, 16 December 2019 (UTC)[reply]

Question I'm the proposer but I've found that exists Global Trade Item Number (P3962). Would this proposal be a duplication? Also ISBN-13 (P212) is a subset of EAN-13 so of GTIN-13, but maybe is more precise. If it's duplicate we can close this request. --AlessioMela (talk) 10:28, 16 December 2019 (UTC)[reply]
- @AlessioMela: EAN is one of the aliases for Global Trade Item Number (P3962), is that the same as EAN-13? It seems likely these are the same thing. ArthurPSmith (talk) 18:37, 16 December 2019 (UTC)[reply]
  - @ArthurPSmith: GTIN is the global standard, EAN is the European one: EAN is a possibile encoding of GTIN (it's explained well at https://en.wikipedia.org/wiki/Global_Trade_Item_Number#Format_and_encodings). Said that, I don't know how to proceed. --AlessioMela (talk) 19:13, 16 December 2019 (UTC)[reply]
I see no good reason for having this in addition to out GTIN property. @AlessioMela: if you think so as well you can set |status = withdrawn. ChristianKl ❪✉❫ 17:10, 17 December 2019 (UTC)[reply]
