title: What does "hidden-link:" mean in Azure Resource Manager Tags
body: <p>I exported an Azure Resource Manager JSON template from my resource group on Azure. I see a bunch of tags in the generated file like:</p>
  
  <pre><code>"tags": {
      "hidden-link:/subscriptions/[my-subscription-id-here]/resourceGroups/[my-resource-group]/providers/Microsoft.Sql/servers/[my-database-server-name]/databases/[my-database-name]": "Resource"
  },
  </code></pre>
  
  <p>The only documentation I can find on it is from <a href="https://azure.microsoft.com/en-us/documentation/articles/resource-group-using-tags/" rel="noreferrer" title="Using tags to organize your Azure resources">Using tags to organize your Azure resources</a>, which says:</p>
  
  <blockquote>
    <p>You may see tags that start with "hidden-" and "link:". These are internal tags, which you should ignore and avoid changing.</p>
  </blockquote>
  
  <p>The problem is that I'm going to be deploying this resource template to a completely different subscription than the one whose ID is hard-coded into the tag. Any meaning that the hard-coded subscription id has in this tag will be lost. Can I safely remove this tag? What does it mean, and how is it used once deployed?</p>
