RDFa

RDFa (Resource Description Framework in Attributes) is a way to add structured metadata to web pages using standard HTML tags. It allows webmasters to embed extra information about the content—such as what a product, person, or event is—directly within the webpage's code. This structured data helps search engines and other applications better understand the content, improving search results and enabling richer features like enhanced listings or data integration. Essentially, RDFa makes webpage content more machine-readable without altering how it appears to users.
