I'm not concerned. I'm actually quite happy about the quick adoption it got.

Yeah, that would be nice. Till they update it, you can either use Google's Email Markup Tester https://www.google.com/webmasters/markup-tester/ or Yandex Structured Data Validator http://webmaster.yandex.ru/microtest.xml > I can't help feeling that this apparent limitation in Google's Structured Data > Testing Tool might be severely reducing the confidence of people to try using JSON-LD > markup in their web pages if they keep seeing "No data detected", even though JSON-LD is > perhaps more convenient for processing by smartphone apps and less brittle than RDFa or > Microdata when for example someone else puts a new hyperlink around an existing image > <img> element that is already semantically annotated. Yep, that's probably true. -- Markus Lanthaler @markuslanthaler
