retailer -> product description page, which property?

Dear all,

Imagine a retailer's product description page, such as

https://www.tesco.com/groceries/en-GB/products/254880991

and the brand-owned product description page, in this case

https://www.marmite.co.uk/products/marmite-big-jar-250g

What's the relationship between those two pages?

Looking at [1], it looks like it should be one of:

- mainEntity (problem: domain is CreativeWork rather than Product which 
is how we see it);

- url: The url property should be reserved to refer to more official or 
authoritative web pages, such as the item’s official website - definite 
candidate);

- about (a bit vague)

- sameAs: The sameAs property also relates a thing to a page that 
indirectly identifies it. Could be.

URL seems the best fit but does it feel right? sameAs seems very 
relevant too. Context: we (GS1) are defining a common syntax for URIs 
that encode our identifiers (including GTINs) and working to make them 
all resolvable and this is tied in with that effort.

Thanks

Phil
