WARNING: This is beta software, there are bugs. This tool is not yet ready for production use. That said, it's pretty useful already, and the bugs preventing production use will be sorted out soon.
Play around with JSON-LD markup by typing out some JSON below and seeing what gets generated from it at the bottom of the page. Pick any of the examples below to get started. The specification is a work in progress.
NOTE: Schema.org's remote context was detected in your input but, unfortunately, it doesn't resolve to a proper context document yet. The Schema.org team is already working on this issue and it is expected to be resolved in a couple of weeks.
In the meantime, if you wish, you can use an alternative context created by the JSON-LD community to process your document.
