RDFa

Also known as: Resource Description Framework in Attributes

A way to embed linked data in document attributes, such as HTML.

A practical example

A publisher describes the author and meaning of page sections.

What should I know?

It is an alternative data format, not a separate ranking factor.

Data and entities in practice

First identify the object you're describing and your evidence. A product, offer, brand, and seller may need separate identifiers. Machine-readable data should match information customers can see and understand.
