HTML (Encodings) | Named Graph

The HTML (HyperText Markup Language) encoding is used for web pages and browsers that people access everyday. Search engines and other data integrations use these web pages, too, but they can also look for machine-friendly data embedded in these HTML documents. This encoding provides an HTML5-compliant DOM, and then one of the following encodings can access the embedded data.

JSON-LD
Microdata
RDFa

Although web pages may technically use any vocabulary, Schema.org is the most widely-used and is supported by search engines like Bing, Google, and Yandex to improve search results.
