I just pushed the first set of improvements to Parse This to support JSON-LD.  Parse This takes an incoming URL and converts  it to mf2 or jf2. It is used by Post Kinds and by Yarns Microsub  to handle this.

So, assuming the default arguments are set, the parser will, for a URL that is not a feed, look for microformats. If microformats lack a summary, content, or references(for jf2) property, it will try to parse JSON-LD. If this produces no results, it will try OGP and Meta Tags.

Even though I’m not fond of Schema.org or JSON-LD, more sites have rich data in  this format than Microformats and I want to be able to find author names and other properties  to display proper attribution and rich link previews for my replies, bookmarks, etc.

This will be available from the Github Repo for Parse This immediately, and will likely be available in the next refreshed release of any plugin using the library. JSON-LD will not be of much use to Yarns, as it does not parse single pages, only feeds at this time.
