Re: Things for Sale vs Reference Information

Short answer:
Use Product or Service for the things.
Use Offer for any statement to transfer or grant rights on the thing for a compensation (e.g. a monetary amount).

GoodRelations is the conceptual basis for the e-commerce part of schema.org.

You can (but don’t have to) be more precise wrt whether the thing is a single, identifiable item (like a particular iPhone with a certain serial number, as in an eBay auction), a bag of multiple identical products (like those on an Amazon offer), or the datasheetnor product model (e.g. on a manufacturer’s page).

See the subclasses of schema:Product for details.

Best wishes

It seems to me that a Thing page should be able to describe itself as one or the other.  This can assist people by differentiating between searches for people looking to buy something vs people looking to learn more about something.
