Schema.org: Store with multiple locations

Question

I have to build the structured data for a store site, but this store is not located only at one place, it has about 5 subsidiaries, so I'm not sure if I have to create multiple Store item type or create an Organization and inside define the multiple subsidiaries.

This is what I have for one store only:

<div itemscope itemtype="http://schema.org/Store">
    <div>
        <h3 itemprop="name">Store 1</h3>
    </div>
    <address itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
        <span itemprop="streetAddress">1234 Fake St</span>,
        <span itemprop="addressLocality">Locality</span>,
        <span itemprop="addressRegion">Region</span>, <span itemprop="addressCountry">Country</span>
    </address>
    <a itemprop="map" content="http://www.google.com" href="http://www.google.com">map</a>
    <div>
        <p><time itemprop="openingHours" datetime="Mo-Su 10:00-21:00">Every day 10am-21pm </time></p>
        <p>Tel. <span itemprop="telephone" content="+1111111111">(1) 1111111 11</span></p>
    </div>
</div>

Should I repeat the above for each Store? Or need I to wrap Stores within an Organization?

Answer 1

I found the answer here: Using itemprop="branchOf" from schema.org Microdata to refer to LocalBusiness's parent company

So, I have to declare the Organization with an id, and then use the itemref property.
