thanks for the initiative - very valuable!

You can use http://developer.search.yahoo.com/help/objects/product

A few comments as for the data:

What you find in Freebase are likely gr:ProductOrServiceModel instances, 
not offers.  So you should create instances of gr:ProductOrServiceModel 
for each "Product" in Freebase first.

Those define the properties of the model - e.g. that what you would 
usually find in a manufacturer's datasheet:

- description
- image
- EAN/UPC
- weight
etc.

Note that the price is not a feature of the product model, but a 
property of one specific offer to sell such objects, i.e. a gr:Offering. 
(I assume there will be way more product models in Freebase than those 
which you find currently, and it could be that querying for a price is 
the reason.)

If you have a business entity and a price, you could also add a 
gr:Offering etc. as you are doing right now. But note that Mattel will 
often not sell individual barbie dolls to end users at the suggested 
retail price. So the offer must be constrained to resellers. And then 
you don't have  price...

This is why I would suggest to limit the export to the model data. Those 
can be linked in the LOD cloud to actual offers, e.g. from BestBuy or 
from eBay (via OpenLink's new eBay sponger).

So the basic structure should be

a) Model data ("Datasheets")

foo:Barbie1234 a gr:ProductOrServiceModel;
 rdfs:label "blabla"@en;
 rdfs:comment "blabla"@en;
 gr:hasEAN_UCC-13 "1234567890123"^^xsd:string;
 gr:hasManufacturer foo:Mattel.
#etc.

foo:Mattel a gr:BusinessEntity.
gr:legalName "Mattel Toys Inc."@en.
#etc.

You can add the statement that Mattel also offers individuals of that type:

foo:Offer a gr:Offering;
    gr:includes foo:SomeBarbie1234s.

foo:Mattel gr:offers foo:Offer.

foo:SomeBarbie1234s a gr:ProductOrServicesSomeInstancesPlaceholder;
 rdfs:label "blabla"@en;
 rdfs:comment "blabla"@en;
 gr:hasEAN_UCC-13 "1234567890123"^^xsd:string;
 gr:hasMakeAndModel foo:Barbie1234.
#etc.

But then you should not attach a UnitPriceSpecification.

For your reference, I add a list of properties for gr:Offering, 
gr:ProductOrServiceModel, and gr:ProductOrServicesSomeInstancesPlaceholder.
Also, I recommend the UML diagram at
