Question

This is my first time using the schema.org schemas and as luck would have it, the item I am trying to put into the a schema doesn’t exactly fit.

To give you an idea. I have a food product, which has nutritional and allergy details which seems to match up well with the recipy schema. However, my problem is exactly this: It’s a product, not a recipe.

Can I embed the recipe schema within a div that has the product schema details?

I.e.

<div itemtype="http://schema.org/Product">
    <div itemtype="http://schema.org/Recipe">
        <div itemtype="http://schema.org/Nutrition">
            @* Nutrition goes here *@
        </div>
        <div itemtype="http://schema.org/Allergy">
            @* Allergy goes here *@
        </div>
   </div
</div>

Answer 1

You’ll want to use additionalType

An additional type for the item, typically used for adding more
specific types from external vocabularies in microdata syntax. This is
a relationship between something and a class that the thing is in. In
RDFa syntax, it is better to use the native RDFa syntax – the ‘typeof’
attribute – for multiple types. Schema.org tools may have only weaker
understanding of extra types, in particular those defined externally.

From http://schema.org/Recipe

Example:

<div itemscope itemtype="http://schema.org/Product" additionalType="http://schema.org/Recipe">
    <div itemscope itemtype="http://schema.org/Nutrition">
        @* Nutrition goes here *@
    </div>
    <div itemscope itemtype="http://schema.org/Allergy">
        @* Allergy goes here *@
    </div>
</div>

My guess would be you want to do this because you are selling recipes or something similar. As the quote above says, Schema.org tools may have a weaker understanding of why you’ve used http://schema.org/Product and http://schema.org/Recipe but at least you have prepared for any possible understanding of this use.
