: Any way to validate Schema.org JSON-LD before publishing? I have a site with a lot of data, and I'm dynamically building JSON-LD data that I think is Schema.org correct. I can't find a dead-on

The "Structured data validator" supports JSON-LD.

Pls, take into account that in order to check JSON-LD you need to put it in tag (since this is how it should be embedded into html).
E.g.,

<script type="application/ld+json">{
"@context":"http://schema.org",
"@type" : "CommunicateAction",
"instrument" : {
"@type" : "EmailMessage"
},
"handler" : {
"@type" : "WebHandler",
"url" : "http://www.example.com/send_email"
}
}
</script>




Tools from Google


The "Email Markup Tester" supports JSON-LD, which could also be used for JSON-LD intended for web pages.

While Google's Structured Data Testing Tool doesn't support JSON-LD, we do
have an Email Markup Tester g.co/EmailMarkupTester that does --
tailored, as you might guess, to the use cases supported by
Gmail<https://developers.google.com/gmail/actions/reference/formats/json-ld>.
Still, it's possible to paste in arbitrary JSON-LD (in a script tag, as
with Yandex's tool).

Update 2015-01: Google has released a new Structured Data Testing Tool with "Expanded support for the JSON-LD markup syntax":
