I am adding Schema.org Microdata to one of the website homepage. This website has a logo which is surrounded with <a> anchor tag. This anchor tag already uses itemprop="url" like this:

<a href="https://mywebsite.com" itemprop="url" title="'My Website'" rel="home" id="logo"><img src="/logo.png" alt="My Website" itemprop="logo" /></a> 

Should I add <meta> tag with itemprop="url" or having <a> with itemprop="url" is enough?

Which one is correct?

One:

<header id="header" role="banner">   <div itemprop="publisher"  >     <a href="https://mywebsite.com" itemprop="url" title="'My Website'" rel="home" id="logo"><img src="/logo.png" alt="My Website" itemprop="logo" /></a>     <meta  content="My Website" />     <meta itemprop="telephone" content="+61 123 123 123" />     <div itemprop="address"  itemtype="http://schema.org/PostalAddress">       <meta itemprop="streetAddress" content="Level 1" />       <meta itemprop="addressLocality" content="SomeCity" />       <meta itemprop="addressCountry" content="AU" />       <meta itemprop="postalCode" content="4000" />     </div>   </div> </header> 

Two:

<header id="header" role="banner">   <div itemprop="publisher"  >     <a href="https://mywebsite.com" itemprop="url" title="'My Website'" rel="home" id="logo"><img src="/logo.png" alt="My Website" itemprop="logo" /></a>     <meta itemprop="url" content="https://mywebsite.com">     <meta  content="My Website" />     <meta itemprop="telephone" content="+61 123 123 123" />     <div itemprop="address"  itemtype="http://schema.org/PostalAddress">       <meta itemprop="streetAddress" content="Level 1" />       <meta itemprop="addressLocality" content="SomeCity" />       <meta itemprop="addressCountry" content="AU" />       <meta itemprop="postalCode" content="4000" />     </div>   </div> </header> 

Format Two has extra <meta itemprop="url" content="https://mywebsite.com">.
