What is

Schema.org

Schema.org

Schema.org is a way to standardize, maintain and promote structured data on the internet.

 

It was founded by Google, Microsoft, Yahoo and Yandex.

 

Schema.org can be used with many different encodings, including Microdata, JSON-LD and RDFa.

Why use

Schema.org

Why?

Schema.org helps search engines to better understand your data (content) with addition of structured data markup.

Markup can become a display feature for a snippet.

If all necessary information is displayed in snippet; price, picture, rating, etc., user will know what exactly they're looking for on a search result landing page.

How to use

Schema.org

Markup Your Content

  1. itemscope & itemtype
  2. itemprop
  3. Embedded items

The basics:

Google: "My name is Google.

I know everything."

Markup Your Content

Format: Microdata

Without Schema.org Markup

<div>
 <span>The Avengers</span>
 <span>Director: Russo Brothers</span>
 <span>Science fiction</span>
 <a href="../movies/the-avengers-trailer.html">Trailer</a>
</div>

1a. itemscope

Add itemscope

Add itemscope to the HTML tag that encloses information about the item.

By adding it, the HTML contained in the <div>...</div> block is about a particular item.

Search engines will not have much information to index our content unless we provide it enough.

<div itemscope>
 <span>The Avengers</span>
 <span>Director: Russo Brothers</span>
 <span>Science fiction</span>
 <a href="../movies/the-avengers-trailer.html">Trailer</a>
</div>

Google: "What is this about? A movie? A book? A toy?"

Markup Your Content

1b. itemtype

Add itemtype

 Add itemtype to specify the type of item immediately after the itemscope.

This specifies that the item contained in the div is a Movie, as defined in the schema.org type hierarchy.

Item types are provided as URLs, in this case http://schema.org/Movie.

<div itemscope itemtype="http://schema.org/Movie">
 <span>The Avengers</span>
 <span>Director: Russo Brothers</span>
 <span>Science fiction</span>
 <a href="../movies/the-avengers-trailer.html">Trailer</a>
</div>

Google: "Now you're talking. The title is 'Science fiction' right?"

Markup Your Content

2. itemprop

Add itemprop

Additional information about itemtype is necessary for search engine.

Add properties for the item by adding itemprop to the element enclosing the item. E.g. Add itemprop="name" to the movie title element.

Now search engines can now finally understand it is about a science fiction movie The Avengers, directed by Russo Brothers.

<div itemscope itemtype="http://schema.org/Movie">
 <span itemprop="name">The Avengers</span>
 <span>Director: <span itemprop="director">Russo Brothers</span>
 <span itemprop="genre">Science fiction</span>
 <a href="../movies/the-avengers-trailer.html" itemprop="trailer">Trailer</a>
</div>

Google: "Too much information..!"

"Now that you know the basics,

you can do the rest."

Google: "Is Russo Brothers a washing machine...?"

Markup Your Content

3. Embedded items

Add embedded items

Sometimes the value of an item property can itself be another item with its own set of properties.

For example, we can specify that the director of the movie is an item of type Person and the Person has the properties name.

To specify that the value of a property is another item, insert a new itemscope immediately after the corresponding itemprop.

<div itemscope itemtype="http://schema.org/Movie">
   <span itemprop="name">The Avengers</span>
   <div itemprop="director" itemscope itemtype="http://schema.org/Person">Director: <span itemprop="name">Russo Brothers</span>

   </div>
   <span itemprop="genre">Science fiction</span>
   <a href="../movies/the-avengers-trailer.html" itemprop="trailer">Trailer</a>
</div>

Google: "Now I know everything. Without you, I'm Baidu"

What is

Types & Properties

Types & Properties

Schema.org describes a variety of item types (itemtype), each of which has its own set of properties (itemprop) that can be used to describe the item.

Thing

Place

Organization

LocalBusiness, Residence, Accommodation etc.

LocalBusiness, Corporation, NGO, Project etc.

*LocalBusiness may inherit properties from both Place & Organization

'Thing' is the most generic type of item.

Type can have many specific types, and a specific type can have many different parent types.

A specific type can inherit all properties from its parent type(s).

Example:

Type Hierarchy

Schema.org type hierarchy is a collection of types (or "classes"), each of which has one or more parent types.

A type may have more than one super-type or parent (E.g. LocalBusiness) and may inherit properties from its parent.

Example:

Full hierarchy can be found here, https://schema.org/docs/full.html

Advance Schema.org

1. Date, Time, Duration

  • How to read the format, E.g. 05/06/2020 means 5 June 2020 or 6 May 2020?
  • Use the time tag along with the datetime attribute, The value of the datetime attribute is the date specified using YYYY-MM-DD format. <time datetime="2020-06-05">05/06/2020</time>

2. Enumeration & Canonical Reference

  • How to give possible value for properties, E.g. <span itemprop="availability">Available today!</span>
  • Use link and href to unambiguously specify the availability as one of the permitted values, <link itemprop="availability" href="http://schema.org/InStock"/>Available today!​

Advance Schema.org

​3. Missing or Implicit Information

  • How to markup information conveyed in an image represents a rating 4 out of 5, E.g. <img src="four-stars.jpg" />Based on 25 user ratings
  • Use meta tag with content, <div itemprop="reviews" itemscope itemtype="http://schema.org/AggregateRating"><img src="four-stars.jpg" /><meta itemprop="ratingValue" content="4" /><meta itemprop="bestRating" content="5" />Based on <span itemprop="ratingCount">25</span> user ratings </div>

Advance Schema.org

Extending Schema.org

Most sites and organizations will not have a reason to extend schema.org.

However, schema.org offers the ability to specify additional properties or sub-types to existing types.

For example, in 2020, Schema.org extend new vocabulary for Covid Hospital Data for US CDC.

1 new type: Thing > Intangible > StructuredValue > CDCPMDRecord

14 new properties: cvdCollectionDate, cvdNumBeds, cvdNumTotBeds, cvdNumBedsOcc, cvdNumICUBeds, cvdNumICUBedsOcc, cvdNumVent, cvdNumVentUse, cvdNumC19HospPats, cvdNumC19MechVentPats, cvdNumC19HOPats, cvdNumC19OverflowPats, cvdNumC19OFMechVentPats, cvdNumC19Died.
