I've been unable to get Webmaster tools to see my sites structured data. It keeps reporting "We do not detect any structured data on your site".
You can inspect my html by visiting: http://www.cgtag.com
I can verify that my Schema.org data is formatted correctly using Yandex. It reports 50 objects on my home page.
http://webmaster.yandex.com/microtest.xml
On my home page in the <head>
section I have this object.
<script type="application/ld+json">{"@context":"http:\/\/schema.org","@type":"CollectionPage","description":"Everything Related To Computer Graphics, Visual Effects and 3D Animation","name":"cgTag | Everything Related To Computer Graphics, Visual Effects and 3D Animation","alternateName":"cgTag"}</script>
For each article shown on the home page, and inside each <article>
tag. I have an object like this.
<script type="application/ld+json">{"@context":"http:\/\/schema.org","@type":"Article","name":"TRANSFORMERS 4 Trailer 2","headline":"TRANSFORMERS 4 Trailer 2","description":"TRANSFORMERS 4 Trailer 2\nParamount Pictures has released the new trailer for Transformers: Age of Extinction, hitting theaters on June 27.\nTransformers: Age of Extinction is the fourth film in director Michael Bay\u00e2\u0080\u0099s global blockbuster franchise.

The only thing I can conclude. Is that Google is ignoring Schema.org data defined in <script type="application/ld+json>
blocks.
This seems like an unlike answer, because it's well documented that defining microdata this way is allowed.
If I use the Google structure data inspector. It's not showing data for the articles.

EDIT: It's been over a month now waiting for the data to appear.
