itemscope is a boolean global attribute that defines the scope of associated metadata. Specifying the itemscope attribute for an element creates a new item, which results in a number of name-value pairs that are associated with the element. A related attribute, itemtype, is used to specify the valid URL of a vocabulary (such as schema.org) that describes the item and its properties context. In each of the following examples, the vocabulary is from schema.org.

Every HTML element may have an itemscope attribute specified. An itemscope element that does not have an associated itemtype must have an associated itemref.

Note: Find more about itemtype attributes at http://schema.org/Thing

Simple example

HTML

The following example specifies the itemscope attribute. The example specifies the itemtype as "http://schema.org/Movie", and specifies three related itemprop attributes. 

<div itemscope itemtype ="http://schema.org/Movie">
  <h1 itemprop="name">Avatar</h1>
  <span>Director: <span itemprop="director">James Cameron</span> (born August 16, 1954)</span>
  <span itemprop="genre">Science fiction</span>
  <a href="https://youtu.be/0AY1XIkX7bY" itemprop="trailer">Trailer</a>
</div>

 

Structured data

The following table shows the structured data from the preceding example.

itemscope Itemtype Movie
itemprop (itemprop name) (itemprop value)
itemprop director James Cameron
itemprop genre Science Fiction
itemprop name Avatar
itemprop https://youtu.be/0AY1XIkX7bY Trailer

itemscope id attributes

When you specify the itemscope attribute for an element, a new item is created. The item consists of a group of name-value pairs. For elements with an itemscope attribute and an itemtype attribute,  you may also specify an id attribute. You can use the id attribute to set a global identifier for the new item. A global identifier allows the item to relate to other items found on pages across the Web.

Example

There are four itemscope attributes in the following example. Each itemscope attribute sets the scope of its corresponding itemptype attribute. The itemtypes, Recipe, AggregateRating, and NutritionInformation in the following example are part of the schema.org structured data for a recipe, as specified by the first itemptype, http://schema.org/Recipe.

<div itemscope itemtype="http://schema.org/Recipe">
<h2 itemprop="name">Grandma's Holiday Apple Pie</h2>
