On Google's page About Schema.org it is stated:
JSON-LD is the newest and simplest markup format... Google is in the process of adding JSON-LD support to more markup-powered features. So far, JSON-LD is supported for all Knowledge Graph features, sitelink search boxes, Event Rich Snippets, and Recipe Rich Snippets; Google recommends the use of JSON-LD for those features. For the remaining Rich Snippets types and breadcrumbs, Google recommends the use of microdata or RDFa.
Yet on the page Enabling Rich Snippets for Articles JSON-LD is shown in the examples as the first way to format article schema markup. Additionally, in the Markup Helper Tool article schema markup can be output as JSON-LD.
Seeing as one page does not list Rich Snippets for articles as a supported use of JSON-LD, and any uses not listed there are not recommended, one would think that it is not available for use. Then why is JSON-LD listed as an example, the first example no less, on the page about rich snippets for articles? A bit confusing.
I would like to begin using JSON-LD as the schema format for our site's articles, but only if it is certain that Google does in fact support its use. Could I get an official answer on the state of JSON-LD formatted schema markup support regarding article rich snippets from Google Support?
