Re: schema.org and proto-data, was Re: schema.org as reconstructed from the human-readable information at schema.org

[quote]2. http://schema.org/Product defines over 20 properties that can be used to describe products. Nevertheless out of the 14.000 websites that we found to use this class, around 50% only use three properties to describe products: Name, Description and Image.[/quote]

I bet the number of properties used would increase IF there were better examples at http://schema.org/Product
The documentation(examples) is POOR at best.
