Bing — supports JSON-LD, schema.org, Microdata, Microformats, Open Graph, RDFa via the Markup Validator (August 2018)

Claim: "Bing works hard to understand the content of a page and one of the clues that Bing uses is structured data." Bing supports JSON-LD, schema.org, Microdata, Microformats, Open Graph, and RDFa via its Markup Validator.

Confidence: Verified — primary (Bing announcement).

Caveat: Bing's current rich-results behaviour is documented mainly via this 2018 announcement and third-party SEO guides; less actively maintained primary documentation than Google's.

Why this matters for Candid: The structured-records story is not Google-only — the same markup eligibilities apply to Bing (and, increasingly, AI engines that consume Bing index data). Pair with Google Search Central — structured data labels each individual element so users can search by ingredient, calorie count, cook time for full coverage.
