Unique Identifiers about schemas

[cmbirk]

We likely will have both. Taking a look at schema.org/product It looks like a UPC would be a gtin value, whereas sku has its own attribute as vendor-specific.

[cmbirk]

Added to the product schema.

Do we need to save Seller SKU and Retailer SKU? Or just SD's internal SKU?

Also - and making a new ticket for this - is a Product saved at a Style level or a SKU level? If it's at a Style level, a Product will have many SKUs. #9

[cmbirk]

I think this is in reference to a product-level sku

[Kaschman]

sku-level product? : ) haha

We will almost certainly want to have https://en.wikipedia.org/wiki/International_Article_Number built in somehow, and because this is mapping to the SD stuff, we will need to figure out how to map from an EAN (public standard) to SD's internal SKU (purely an SD product ID).

I do not know how an EAN gets built up.

An SD SKU is built along the lines of 0011223344

00 Department
11 Category
22 Style
33 Color
44 Size

This is not exactly right but close enough to give you a gist.

Please make sure with some of these questions you queue them up in a questions list to talk to people (like Dave Barton) about so we are matching existing accepted practices where relevant

[cmbirk]

Yep. Regular SKU fits for SD-specific here. Will open a ticket for the International Article Number

ok it looks like GTIN is a 12 digit code, IAN is a 13 digit code
https://www.gs1uk.org/our-industries/retail/selling-on-marketplaces/ultimate-guide-to-gtins-eans-and-upcs-for-amazon-ebay-google
you can convert GTIN to IAN by adding a 0 - should we be saving everything as IAN?

[Kaschman]

oh hang on - Schema.org has this. https://schema.org/gtin
a 13-digit number is an IAN, a 12 digit number is a GTIN

[cmbirk]

Yep, and GS1 is a specific standards organization that registers your product ids. It's the org that Eytan told us about previously. Not sure it would benefit us to go down that path at this moment.

[Kaschman]

what path specifically? Seems to me we need to add a 'gtin' field that can take a 12 or 13 digit numeric value and serves as a unique identifier for a product

[cmbirk]

I believe GTIN codes are specifically assigned from GS1 ( see https://schema.org/gtin12 ). They aren't any generic 12 or 13 digit values. We can use a different identifier for a non-GS1 code.

[Kaschman]

we need GTIN for sure
the SKU is an internal identifier from the seller whether it is a marketplace seller or SD - it is the owner of the inventory

should SKU be a part of inventory?

SD SKU is optional (check on this with RC/Bob's)
unsure if seller SKU needs to be included
