Request for Content Metadata Samples

I'm toying with the idea of writing a converter that would consume content metadata and export a complete Amazon Creator compatible feed file.  I've already done this for Direct Publisher.  I've been searching for content metadata samples, but, all I've found is the doc Content Metadata.

Does anyone have samples of content metadata that an SDK channel consumes to display video contents?  Would you be willing to share? 

XML and JSON are acceptable.
