schema.org

With Facebook we have the Open Graph tags that allow webmasters to specify how the story is displayed on Facebook. Is there something similar for the Google +1 button, that allows webmasters to specify the thumbnail image, description and title? Google+ seems to be ignoring the og-meta tags . texmex5 From Google+ help docs, we now have an official answer . Google uses schema.org microdata to generate rich snippets in search (and in Google+). There's a lot written about schema.org and how it relates to Facebook OpenGraph in these two links: See: http://www.google.com/support/webmasters/bin

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

What is the difference between the Schema.org properties isPartOf and hasPart and when to use the one instead of the other? As noted on their pages, they are inverse properties . As an example, let’s take a webpage that is part of a website. You could then state one of these: WebSite hasPart WebPage WebPage isPartOf WebSite It doesn’t matter which one you choose. (But there might of course be consumers that only recognize one of these properties.) Note: Most of the time, Schema.org doesn’t define an inverse equivalent for a property. For example, there is author , but no authorOf . This is

I have to model a product, which has properties that aren't listed in the Schema.org Product type. After seeking in many places, I didn't find anything that fits to my need. How can I extend the Schema.org Product type? You could always use other vocabularies (that offer the properties you need) in addition to Schema.org. But if you want to use only the vocabulary Schema.org, you have two options in general: Propose new properties (or classes). You can do this on Schema.org W3C Community Group ’s mailing list , or on Schema.org’s GitHub issue tracker . See: How can I get involved? How can I

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? Simplified version (no address,

I want to add Corporate Contacts in Google Search. I test the following code in Google's Structured Data Testing Tool , but it threw this error: https://coda-resume.herokuapp.com/ (All values provided for http://www.example.com/ must have the same domain.) Here is the JSON-LD: <script type="application/ld+json"> { "@context": "http://schema.org", "@type": "Organization", "url": "https://coda-resume.herokuapp.com/", "logo": "http://www.example.com/logo.png", "contactPoint": [{ "@type": "ContactPoint", "telephone": "+1-401-555-1212", "contactType": "customer service" }] } </script> (I put this
