Help making an example combining eocred ideas with fact-checking markup?

Hi! Could folk here help sketch an example where we describe the author of
a Book, ScholarlyArticle, NewsArticle, Podcast or fact-checkable Claim
(c.f. http://schema.org/ClaimReview) using eocred vocabularies and patterns.

This largely pertains to fact-checking; perhaps describing the claim maker,
or perhaps, the fact checker.

 What kinds of ways might eg "expertize in climate change" or "vaccines" or
"nuclear power station building and systems" be indicated? what are the
expressivity limits? what other idioms (eg employment history)?

I could share a guess but would love to see an independent take on this...
