Getting Started. Most webmasters are familiar with HTML tags on their pages. Usually, HTML tags tell the browser how to display the information included in the tag. For example, <h1>Avatar</h1> tells the browser to display the text string "Avatar" in a heading 1 format. However, the HTML tag doesn't give any information about what that text string means—"Avatar" could refer to the hugely successful 3D movie, or it could refer to a type of profile picture—and this can make it more difficult for search engines to intelligently display relevant content to a user. Schema.org provides a collection of shared vocabularies webmasters can use to mark up their pages in ways that can be understood by the major search engines: Google, Microsoft, Yandex and Yahoo! You use the schema.org vocabulary, along with the microdata format, to add information to your HTML content.
While the long term goal is to support a wider range of formats, the initial focus is on Microdata. 1. 1a. 1b. itemscope and itemtype Back to top 1d.
RDFa, Microdata and Microformats. Microformats 2 and RDFa Collaboration. 2. Welcome to the microformats 2 home page. Summary Microformats 2 improves ease of use and implementation for both authors (publishers) and developers (parser implementers), with the following simplifications: prefixes for which class names are used for microformats, those that start with 'h-' 'p-' 'u-' 'dt-', 'e-' = syntax independent from vocabularies which can then be developed separately. 'h-*' for root class names, e.g. 'h-card' 'p-*' for simple (text) properties, e.g. Simple microformats 2 examples Here are a few simple microformats 2 examples the demonstrate a most of the changes, along with canonical JSON. Simple person reference: <span class="h-card">Frances Berriman</span> Parsed JSON: Simple hyperlinked person reference <a class="h-card" href=" Ward</a> Simple hyperlinked person image Additional simple cases details in microformats-2-implied-properties.

Google, Microsoft, and Yahoo have teamed up to encourage Web page operators to make the meaning of their pages understandable to search engines. The move may finally encourage widespread use of technology that makes online information as comprehensible to computers as it is to humans. If the effort works, the result will be not only better search results, but also a wave of other intelligent apps and services able to understand online information almost as well as we do.
The three big Web companies launched the initiative, known as Schema.org, last week. It defines an interconnected vocabulary of terms that can be added to the HTML markup of a Web page to communicate the meaning of concepts on the page. The move represents a major advance in a campaign initiated in 2001 by Tim Berners-Lee, the inventor of the Web, to enable software to access the meaning of online content—a vision known as the “semantic Web.”
FAQ. What is the purpose of schema.org? Why are Google, Bing, Yandex and Yahoo! Collaborating? Aren't you competitors? There are lots of schemas out there. Why create a new one? Is schema.org a standards body like the W3C or IETF ? How does schema.org relate to Facebook Open Graph? What's coming next? Who is managing schema.org on an ongoing basis? Is schema.org available in multiple languages? How do I mark up my site using this schema? Why should I add markup? This is too much work. I have already added markup in some other format (i.e. microformats, RDFa, data-vocabulary.org, etc). My website contains content that is of a type that is unsupported. Do I have to mark up every property? Why microdata? Why don't you support other vocabularies such as FOAF, SKOS, etc?
Where can I give feedback, report bugs, etc.? What do you mean by "Schema Version 0.9x" that is on every schema page? Q: What is the purpose of schema.org? Q: Why are Google, Bing, Yandex and Yahoo! Q: There are lots of schemas out there. Live Microdata. Schema.org – One Month In. If you have been following the news from the world of web standards, linked data, and/or semantic web, you certainly have heard about schema.org. If you missed it, schema.org is a collaboration of Google, Yahoo! And Bing and is a way to include structured data in web pages. The vocabulary includes descriptive terms for content like movies, music, organizations, TV shows, products, locations, and more – there are over 100 terms. According to the Schema.org website, the goal is “to improve the display of search results, making it easier for people to find the right web pages.”
Announced just before The San Francisco Semantic Technology Conference, Schema.org was the most heated discussion topic the conference has seen in some time, and since then has been talked about extensively in news publications, podcasts, email discussion boards, and Q&A systems. (In case you missed all the hubub, following is a timeline of some of the early reactions.) Timeline June 3 - schema.rdfs.org is announced. Schema.org adopts IPTC's rNews for news markup. London (England) -- schema.org has added support for rNews, a standard for embedding news publishing metadata into web pages developed by the International Press Telecommunications Council (IPTC).
With this addition, online publishers can now implement IPTC rNews using an approach supported by the Google, Bing and Yahoo! Search engines. Moreover, current implementers of schema.org markup now have access to a powerful new set of news- and publishing-specific properties. Both IPTC rNews and schema.org provide data models for embedding metadata into HTML documents. rNews is the first published addition to schema.org since its launch. "I am thrilled to see IPTC rNews markup incorporated into schema.org," said Evan Sandhaus, IPTC Delegate and Lead Architect For Semantic Platforms at The New York Times Company.
rNews reflects over a year of effort by the IPTC, a broad consortium of news agencies, publishers and system vendors. Implementing Schema.org Microdata. Last week, Google, Bing and Yahoo announced collaboration on a single standard for structured markup. Yes, I’m talking about Schema.org and utilizing Microdata for “Rich Snippets.” Since then, many sites have posted about why Schema.org might be good, bad or otherwise for site owners; some balanced, some not. Personally, I think structured markup and machine-readable information is always good to have on your site, regardless of potential SEO benefits. I’ve had a love for structured markup (in the form of Microformats) since I first laid eyes on hCard several years ago. Then, I started implementing microdata. I started out by making a list of all of the attributes about books that we use in a review.
There were a couple of attributes that were confusing – for example, do I use description or reviewBody from Review? To test that you’ve implemented microdata correctly, you can use Google’s Rich Snippet testing tool.
