This one is huge, and ripe for exploitation. Wanna buy my new supplement? Yes it is USDA Organic, seeeee

Here is an extremely basic example:

certification-json-ld-example.jsonld · 160B test 
{
  "@context": "https://schema.org",
  "@type": "Certification",
  "name": "USDA Organic",
  "url": "https://www.usda.gov/topics/farming/organic-agriculture"
}

Here is an example from Schema.org that I borrowed:

certification-json-ld-example.jsonld · 1.3K test 
{
  "@context": [
    "https://schema.org",
    "https://www.w3.org/ns/credentials/v2"
  ],
  "@type": "VerifiableCredential",

      },

    }
  },
