Re: CreativeWork can't be a Product?

Hello!

I read all your answers  - many thanks for clarifying this issue. As i see there are mainly two approachs to get thing done: "two types approach" and using of additionalType.

It is very helpful to have such workarounds, but they are only workarounds, not a "right" solution. This issue seems to be solvable with just simple change of type passage structure/inheriting, namely: one things must be maked possible, CreatieWork type must can inherit Product type. I mean such inheritance is a simple thing, which is even partly present, on other place: CreativeWork can inherit Offer, but why not Product? Making it possible would make such workarounds like "two types approach" redundant - they are indeed redundant cause of impossibility of inheritance, which is possible on another, near place.

Schema.org has pretty clear structure, maintaining of it provides Schema.org to more users and makes the implementing more easy, selfexplaining and issueless. But if one thing is possible on one place, on another similar place is this not possible and needs workarounds so the whole clear structure of Schema is confused. It is just my feeling.

 describe the book i sell like Product, with product's
 properties - i can't find any passage from CreativeWork to
 Product. There is in fact a passage from Offer to Product,
 with itemprop="itemOffered" itemscope="" itemtype="http://schema.org/Product", but repeating isn't a good
 way, beside of this it isn't easy to get such passage into
 html, even with itemref.

 CreativeWork->Product->Offer (or

 only CreativeWork->Offer, or Product->Offer.
 CreativeWork can't be a Product or am i wrong?

 You can just use both types in the itemtype declaration, for
 example,
 itemtype="Book Product".
 
 We're doing this in the #schemabibex group to express offers
 for a given
 item. And Martin gave a wonderful example of this approach
 on this list
