Validate JSON-LD and Schema.org

Question

I am looking for a good validator to test my Schema.org used in JSON-LD. I searched around but really can't find a good validator to test this.

Anyone knows where I can find a good validator?

The Google validator doesn't validate my JSON-LD.

Example of implementation:

{
  "@context": "http://schema.org",
  "@type": "Person",
  "name": "John Doe",
  "jobTitle": "Graduate research assistant",
  "affiliation": "University of Dreams",
  "additionalName": "Johnny",
  "url": "http://www.example.com",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1234 Peach Drive",
    "addressLocality": "Wonderland",
    "addressRegion": "Georgia"
  }

If you don't run into any errors or warnings in the Structured Data Testing tool then your structured data is validated. Just testing the little snippet you posted, all seems to be ok (but you're missing an ending "}").

If what you're seeking is what markup you should or shouldn't use based on a webpage, one would need more topical information to answer that (and you're not actually looking for a "validator" at that point).
