    Currently (July 2017), Google recommends unsing JSON-LD "wherever possible": developers.google.com/search/docs/guides/intro-structured-data Commented Jul 21, 2017 at 8:11
  • Do I understand right, JSON-LD can only let you specify general info about whole page, but you can't express which exactly parts of the webpage correspond to which object in JSON-LD? Like, if you have a list of books, you can specify in JSON-LD that this page shows a list of books, but you won't be able to tell which of the books described in the JSON-LD correspond to which exactly element on the webpage? If so, Microdata/RDFa have one more important advantage: providing context to screenreaders used by blind people, but maybe I'm missing something in how JSON+LD works. Commented Jun 15, 2023 at 4:55

    @Klesun: Correct, with JSON-LD, there is no native way to connect the HTML elements with the JSON-LD statements. But even with Microdata and RDFa, the HTML is just the carrier. Microdata/RDFa parsers will just extract the statements, without any coupling to the HTML. I suppose it could be conceivable for user agents (like screen readers) to use Microdata/RDFa to get more context about the HTML, but AFAIK no one does that yet, and Microdata/RDFa were not designed for this to begin with.

  • in the case of JSON-LD, why not using anchors to connect HTML elements? Or is it too cumbersome? Commented Dec 15, 2023 at 11:44
  • @Ooker I had similar thoughts. You could adopt that convention. However, many people have not adopted the convention. A tool parsing the file would not know if such convention is followed. Sometimes it would be followed & sometimes not. I wonder what % of implementations fully or partially couple the DOM Element's id with the schema Element's id. Commented Mar 9, 2024 at 16:09
