Schema.Org Newsarticle: Invalid Value for Logo Property

Schema.org NewsArticle: invalid value for logo property

Your markup is valid HTML5+Microdata and you are using the Schema.org vocabulary appropriately.

With "validator", you probably refer to Google’s Structured Data Testing Tool. Note that errors shown in this tool don’t necessarily mean that your markup is wrong; they often mean that you won’t get a certain Google search result feature unless you provide certain properties.

If you want to get this search result feature in Google Search (e.g., the Article Rich Snippet), you have to provide an ImageObject item as value (instead of a URL value) for the logo property.

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

  <div itemprop="logo" itemscope itemtype="http://schema.org/ImageObject">
    <img itemprop="url" src="https://www.mysite.de/resources/assets/71/small/my_logo_web.png" />
    <!-- and Google probably requires some more properties here, e.g. "height" and "width" -->
  </div>

  <span itemprop="name">My Company</span>

</div>

Set logo property on Article sheme

Following structure passes Google test.

<div itemscope itemtype="http://schema.org/Article">    
     <h1 itemprop="headline">Article</h1>
     <div itemprop="image" itemscope itemtype="http://schema.org/ImageObject">
         <img  itemprop="url" src="http://www.example.com/logo.png" alt="Debian Packages">
         <meta itemprop="width" content="220" >
         <meta itemprop="height" content="220" >
    </div>
    <meta itemprop="datePublished" content="2014-08-10">
    <meta itemprop="dateModified" content="2016-06-02">
    <a itemprop="mainEntityOfPage" href="/ArticleLink"></a>
    <div itemprop="author" itemscope itemtype="http://schema.org/Person">
        <meta itemprop="name" content="ArticleAuthor">
    </div>
    <div itemprop="publisher" itemscope itemtype="http://schema.org/Organization">
      <meta itemprop="name" content="PublisherName">
      <a itemprop="url" href="/"> 
      <span itemprop="logo" itemscope itemtype="http://schema.org/ImageObject"  >
      <img itemprop="image" src="http://www.example.com/logo.png" />
      <link itemprop="url" href="http://www.example.com/logo.png" />
      </span>
      </a>
    </div>
</div>

Update

Probably, following is even better.

<div itemscope itemtype="http://schema.org/Article">    
     <h1 itemprop="headline">Article</h1>
     <div itemprop="image" itemscope itemtype="http://schema.org/ImageObject">
         <img  itemprop="url" src="http://www.example.com/logo.png" alt="Debian Packages">
         <meta itemprop="width" content="220" >
         <meta itemprop="height" content="220" >
    </div>
    <meta itemprop="datePublished" content="2014-08-10">
    <meta itemprop="dateModified" content="2016-06-02">
    <a itemprop="mainEntityOfPage" href="/ArticleLink"></a>
    <div itemprop="author" itemscope itemtype="http://schema.org/Person">
        <meta itemprop="name" content="ArticleAuthor">
    </div>
    <div itemprop="publisher" itemscope itemtype="http://schema.org/Organization">
      <meta itemprop="name" content="PublisherName">
      <a itemprop="logo"  itemscope itemtype="http://schema.org/ImageObject" href="/"> 
      <img itemprop="image" src="http://www.example.com/logo.png" />
      <link itemprop="url" href="http://www.example.com/logo.png" />
      </a>
    </div>
</div>

Warning that image and logo have wrong values

Looks like in order to pass the Structured Data Testing Tool you need to use ImageObject as a required property of image and publisher.logo.

From their documentation:

image - ImageObject, required

Your final code will look like:

{
    "@context":"http://schema.org",
    "@type":"BlogPosting",
    "headline":"Fixer la navigation Off-Canvas sur Foundation",
    "image": {
      "@type": "ImageObject",
      "url": "https://google.com/thumbnail1.jpg",
      "height": 800,
      "width": 800
    },
    "author": {
      "@type": "Person",
      "name": "Stéphane Richin"
    },
    "datePublished":"2015-02-03",
    "dateModified":"2015-02-03",
    "publisher": {
        "@type":"Organization",
        "name":"Stéphane Richin",
        "url":"http://stephane-richin.fr",
        "logo": {
          "@type": "ImageObject",
          "url": "https://google.com/logo.jpg",
          "width": 600,
          "height": 60
        }
    },
    "mainEntityOfPage": "True"
}

I also amended it to recognise the author as Person schema.

Schema.org properties logo, mainEntityOfPage, dateModified give error in Google SDTT

It seems that Google has recently changed the requirements for Article rich snippets.

See this link for more information : https://productforums.google.com/forum/#!topic/webmasters/ltbw0gUvReM

And this one for documentation : https://developers.google.com/structured-data/rich-snippets/articles#article_markup_properties

Hope it helps.

Edit for logo :

Follow this link to know how to set up the logo : http://schema.org/logo

Add schema.org article - problem with LOGO

For the publisher, you specified the URL property for the logo:

"publisher":{
     "@type": "Organization",
     "name":"mywebsite",
     "url": "https://www.example.com/logo.jpg",
     "logo": {
         "@type": "imageObject",
         "url": "https://www.example.com/logo.jpg"
     }
  }

However, it requires the URL of the publisher's website but not the logo.

In addition, the problem with a particular logo may be due to the wrong size or format, which you do not report. So check to see how your logo matches Google's Guidelines for Logo.

Unresolved error with validating logo for organization in JSON-LD markup: A value for the 'url' field is required.

It’s a valid use of Schema.org. Google’s SDTT, however, is not a general Schema.org validator. The warnings and errors it reports are primarily about Google’s own search result features, which require the use of specific Schema.org terms in specific contexts.

For the AMP version of Google’s Article rich result, Google requires the publisher property, and the publisher’s logo has to have an ImageObject value instead of a URL value.

"publisher":{
  "@type":"Organization",
  "name":"Orals",
  "logo": {
    "@type": "ImageObject",
    "url": "/logo.png"
  }
},

If you don’t want this Article rich result in Google Search, or if you don’t use AMP, or if you can’t get it for other reasons (e.g., because you can’t provide all required properties), you can safely ignore this error in the SDTT.

Errors in Microdata for image/logo as part of a BlogPosting

In both cases, Google wants to see an ImageObject item (for displaying their Article Rich Snippet).

<div itemprop="logo" itemscope itemtype="http://schema.org/ImageObject">
  <!-- … -->
</div>

<div itemprop="image" itemscope itemtype="http://schema.org/ImageObject">
  <!-- … -->
</div>
