About
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.
SearchAction is a structured data type from Schema.org that describes a website's search capability.
Before November 2024, it was used by 
Google to enable the "Sitelinks Search Box" feature, which displayed a search bar for a website directly within the search results snippet. However, since Google deprecated this feature, there is no evidence that other search engines or apps currently support it.
