About
Microdata is an 
HTML specification used to embed structured metadata within web page content by annotating elements with machine-readable attributes.
It uses attributes such as itemscope, itemtype, and itemprop to define entities and their properties directly in markup, supports vocabularies such as Schema.org, and is one of the structured data formats supported by Google alongside 
JSON-LD and 
RDFa.
RDFa (Resource Description Framework in Attributes) is an extension to HTML5 that embeds structured metadata within page content by adding attributes based on the 
RDF data model.
It uses HTML attributes such as vocab, typeof, and property to describe entities like people, places, events, recipes, and reviews, supports multiple vocabularies such as Schema.org, 
Dublin Core, and 
GoodRelations, and is one of the structured data formats supported by Google alongside JSON-LD and Microdata.
