Microdata, RDFa or JSON-LD Appropriate or best usage?

阅读更多关于 Microdata, RDFa or JSON-LD Appropriate or best usage?

问题 I have been wondering which of those formats is "best"? Schema.org, Microdata, and RDFa are bit of a pain to implement. They can break validation and require quite an effort to put into documents. JSON-LD is, at last for me, a way better to implement structured data. But does it work? What level of support is there for it (at least by Google)? 回答1: Schema.org is a vocabulary that can, like any other vocabulary, be used in many forms. The website http://schema.org/ has examples using Microdata

Why use Schema.org microdata to mark up web page elements?

阅读更多关于 Why use Schema.org microdata to mark up web page elements?

I understand why and how to use Schema.org to add microdata to your site, this is not a question about that.
