What is microdata?
- A standardized way for providing additional semantics in the web pages is called microdata.
- It helps you in defining your own customized elements and it even starts embedding the customized properties into the web pages.
- Microdata consists of a group of name-value pairs at a higher level.
- The groups are known as items. Name-value pairs are known as property. Regular elements represent items and properties.
Global AttributesThere are five global attributes introduced by microdata and available for any element to use:
a) itemscope –
It is used for creating an item. It is a boolean attribute which will tell that there is a presence of microdata on this particular page by denoting its starting point.
b) itemtype –
It is a valid URL that will define the item and provide the context for the properties.
c) itemid –
By using this attribute the global identifier for the item is defined.
d) itemprop –
By using this attribute the property of an item can be defined.
e) itemref –
A list of additional elements to crawl is given by this attribute so that it finds the name-value pairs of the item.
