Re: creator and author syntax question

What Dan said...

Plus: The Google Rich Results Test Tool is only testing for the attributes
that are significant to their [Google's] implementation of Rich Results in
their services.  It is not a general Schema.org test tool such as the
Structured
Data Linter <http://linter.structured-data.org/>, JSON-LD Playground
<https://json-ld.org/playground/>, etc.
