Can I use multiple instances of http://schema.org/Organization?

问题

I have a website which list multiple companies, my markup goes something like this:

<h2>Checkout those cool companies</h2>
<div itemscope="itemscope" itemtype="https://schema.org/Organization">
  <img itemprop="logo" src="logo1.jpg" alt="">
  <h3 itemprop="name">Company1</h3>
  <p itemprop="description">It's a great company</p>
  <span itemprop="url">http://company1.com</span>
</div>

<div itemscope="itemscope" itemtype="https://schema.org/Organization">
  <img itemprop="logo" src="logo2.jpg" alt="">
  <h3 itemprop="name">Company2</h3>
  <p itemprop="description">It's a great company as well</p>
  <span itemprop="url">http://company2.com</span>
</div>

<div itemscope="itemscope" itemtype="https://schema.org/Organization">
  <img itemprop="logo" src="logo3.jpg" alt="">
  <h3 itemprop="name">Company3</h3>
  <p itemprop="description">It's a amazing company</p>
  <span itemprop="url">http://company3.com</span>
</div>

I'm using itemtype="https://schema.org/Organization multiples times in order to help crawler better identify the content.

Is this an appropriate use of https://schema.org/Organization?
How can I make my own https://schema.org/Organization not conflict with the companies markup I'm listing?

Yes, it’s correct to use multiple Organization items for this purpose.

To make clear that your own Organization is not part of this list, you could

provide it as value for author/publisher (of the WebPage), and
provide an ItemList for the list of the other organizations.

In case this list of organizations is the main content for that page, you could use mainEntity (for the ItemList) and use CollectionPage instead of WebPage:

<body itemscope itemtype="http://schema.org/CollectionPage">

  <div itemprop="publisher" itemscope itemtype="http://schema.org/Organization">
  </div>

  <section itemprop="mainEntity" itemscope itemtype="http://schema.org/ItemList">
    <h2>Checkout those <span itemprop="name">cool companies</span></h2>
    <article itemprop="itemListElement" itemscope itemtype="http://schema.org/Organization"></article>
    <article itemprop="itemListElement" itemscope itemtype="http://schema.org/Organization"></article>
    <article itemprop="itemListElement" itemscope itemtype="http://schema.org/Organization"></article>
  </section>

</body>
