How to mark up the “isAccessoryOrSparePartFor” property for a replacement part?

Question

I want to create a rich snippet for a replacement valve for a kitchen faucet.

How do I associate that part to the parent product using Microdata and the isAccessoryOrSparePartFor property?

This is what I have so far:

<div itemprop="isAccessoryOrSparePartFor" itemscope itemtype="http://schema.org/Product">
  <h1 itemprop="name">Replacement Valve 209438</h1>
  <link itemprop="url" href="https://www.example/replacement-valve-209438">
  <link itemprop="model" href="https://www.example.com/kitchen-faucet-220/">
  <!-- more product properties, etc. -->
</div>

How should it look in the Google Rich Snippet Tool--should there be one product or two? Is model the correct property to associate to the parent faucet?

Answer 1

(Google’s Products rich result doesn’t make use of the isAccessoryOrSparePartFor property, so the following is only based on how it can be represented with Schema.org.)

Your structured data conveys: There is a Product (not shown) which is an an accessory/spare part for the Product "Replacement Valve 209438". But you want it the other way around, as far as I understand it.

So it could look like this:

<article itemscope itemtype="http://schema.org/Product">

  <h2 itemprop="name">Replacement Valve 209438</h2>

  <div itemprop="isAccessoryOrSparePartFor" itemscope itemtype="http://schema.org/Product">
    <a itemprop="url" href="/kitchen-faucet-220">
      <span itemprop="name">Kitchen Faucet 220</span>
    </a>
  </div>

</article>

The model property can be used to reference the ProductModel of the Product for which (!) you specify the property.
