How do Google and others determine the value of an itemprop on an Anchor tag? <a href="foo.html" itemprop="barprop">Name Of Link</a> In the example above, is the itemprop's value the href attribute, much like how the link tag is parsed? Or is the value the innerHTML , as a standard block element is parsed? I've searched quite a bit and cannot find the answer. I'm open to all answers, but I'd very much like a source for the answers given so I can further investigate. Thanks in advance! The Microdata spec (which is now merely W3C Note ) defines : If the element is an a , area , or link element

TL;DR --> I want an itemprop nested in one itemscope to actually be applied to a different itemscope. How do I do that? Here's a a gist of the code I have (I've removed classes and other extraneous elements on the page to focus on what's important): <!-- CODE I HAD --> <div itemscope itemtype="http://schema.org/Product"> <div itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating"> <span itemprop="ratingValue">79</span> <h1 itemprop="name">Someproductsoandso</h1> <span itemprop="reviewCount">830</span> </div> </div> <!-- CODE I NOW HAVE --> <div itemscope itemtype=

The Microdata example of Google’s Article Rich Snippet contains this meta element with Schema.org’s mainEntityOfPage property: <meta itemscope itemprop="mainEntityOfPage" itemType="https://schema.org/WebPage" itemid="https://google.com/article"/> When checking it with the Nu Html Checker , I get this error: Element meta is missing required attribute content . Adding an empty content attribute seems to solve this error. Is it correct to do this? unor The Nu Html Checker is correct, Google’s example is invalid. The content attribute is required if the meta element has an itemprop attribute. From

The site I am developing makes use of Microdata (using schema.org). As we are shifting development over to use React to render our views I have hit a blocker where React will only render attributes in the HTML spec however Microdata specifies custom attributes such as itemscope . As I'm relatively new to React and haven't had chance to fully understand the core just yet, my question is what would be the best way to extend the functionality of react.js to allow for defined custom attributes, e.g., Microdata? Is there a way of extending the attributes/props parser or is it a job for a mixin

I have been wondering which of those formats is "best"? Schema.org, Microdata, and RDFa are bit of a pain to implement. They can break validation and require quite an effort to put into documents. JSON-LD is, at last for me, a way better to implement structured data. But does it work? What level of support is there for it (at least by Google)? unor Schema.org is a vocabulary that can, like any other vocabulary, be used in many forms. The website http://schema.org/ has examples using Microdata and the RDF syntaxes RDFa and JSON-LD , but these are not the only syntaxes it can be used with. You

I am getting involved into Microdata and rich snippets for leading better search results. I am kind of confused about where to set the itemscope for a LocalBusiness and if it is good or bad to have it repeated through out the whole website over and over. For example on the header that repeats all over the site, page after page, I have the business name, telephone, address, logo, description, etc. Is it good to repeat the same itemscope over and over on each page, or it should be only added to one page, for instance only on the index or only on the contact page?
