I came to years old posts here on Stack Overflow, discussing Microdata, RDFa etc. I looked on the microformats2 site and it says both have been superseded by microformats2. (https://microformats.org/wiki/rdfa) (https://microformats.org/wiki/microdata). Also Google uses microformats2 for SEO... So my question is, should I only use microformats2 these days if I want to start with SEO? is it the de facto "standard"?
And another thing I'd like to know is, there are extra HTML5 tags to sort of "mark" content as some type of microformat, e.g new tags like <time> and <article>. Do those tags have the same meaning or relevance for search engines like if I would tag them directly with microformat classes (like class="h-article", etc.)?
