Any23 177

Hi Folks
Please see PR for issue ANY23-177 
https://issues.apache.org/jira/browse/ANY23-177
I would like to determine if we can add test(s) to verify JSON-LD triples extraction from HTML.
Can we embed JSON-LD in HTML? I tried adding some trivial markup to a wikipedia entry and adding it as a test case however I was getting parse exceptions.
