Ecommerce Rich Snippets Category Question

[s_EOgi_Bear]

Hello

Technical question:

I have category pages in my site - and product pages in my site.

Category Pages

1. I Have listed Grouped products on them ( i.e. a product that could have multiple offers for each size )
2. I Have the relevant markup for them ( one for each product ) .

Product Pages

1. The Product pages have grouped products as well - but the individual simple products are note marked up.
2. The Product pages have Aggregate reviews on them.

My question is this: Should I use the grouped product sku to identify the grouped product on the category page and the product page?  Technically they aren't Stock Keeping Units ( SKU's ) - but they could be used to link the 2 together to avoid duplicates.

Ideas?

I wouldn't use the SKU property unless it was actually marking up a SKU - marking up something else would probably not be useful or result in a more detailed snippet. Could you use another property to mark up these grouped products instead, like the ProductID property?

Thanks - I'll give it a try!
