What is the new product field "EAN" good for?

Hello,
can anybody tell me what is the purpose of the new field EAN in product properties?
We already have "Artikelnummer" which is translated from "JSHOP_EAN_PRODUCT", appears in backend
as
[code]<input type="text" name="product_ean" class="form-control" id="product_ean" value="123456" onkeyup="jshopAdmin.updateEanForAttrib()" ;="">[/code]

Now there is "EAN" too, in backend [code]<input type="text" name="real_ean" class="form-control" value="123456">[/code]

So what does one use this new field for?
What's the difference between "product_ean" and "real_ean"?

Regards
Uwe

Product code => Your shop product code
EAN => https://uk.wikipedia.org/wiki/European_Article_Number

Thank you,
unfortunately your link is in russian, my russian is a little rusty 40 years after school :-)
But it lead me in the right direction, there is also an english wikipedia article
https://en.wikipedia.org/wiki/International_Article_Number
The International Article Number (also known as European Article Number or EAN) is a standard describing a barcode symbology and numbering system used in global trade to identify a specific retail product type, in a specific packaging configuration, from a specific manufacturer.
Falls es noch jemanden interessiert:
Die EAN ist eine international eindeutige Nummer um Waren und andere Sachen mit einem Barcode zu kennzeichnen. Ein anderes Stichwort ist GTIN.
