What does "hidden link:" mean in Azure Resource Manager Tags

Question

I exported a JSON template for Azure Resource Manager from my resource group on Azure. I see a bunch of tags in the generated file, for example:

"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"
},

The only documentation I can find on it is Using tags to organize your Azure resources , which says:

You can see tags that start with "hidden" and "links:". These are internal tags that should be ignored and not changed.

The problem is that I'm going to deploy this resource template to a completely different subscription than the one whose identifier is hard-coded into the tag. Any value that the hard-coded subscription identifier in this tag will be lost. Can this tag be removed safely? What does this mean and how is it used during deployment?

Answer 1

These tags are used to link related resources. They are used to populate the Related Resources section. Removing tags will prevent the display of resources as related resources, but will not affect any features.

Answer 2

The Azure Resource Manager (ARM) tag is optional for an Azure resource or Azure resource group.
