How do I get the use Json to get the "about" and "mention" property to work with several subjects?

[concerro]

The section of the code I'm having trouble with is starts with "about". I'm not a programmer/developer so I'm sure I'm missing something that's obvious to the rest of you.

You have missed a comma after {@id} in "about". And where us the JSON Schema for it?

[notEthan]

This is schema.org's JSON-LD, which is unrelated to the JSON Schema specification.

Thanks. The comma removed the error I was getting.
