Schema.org JobPosting

HiringOrganization can extend the SchemaPersonOrgBase. That provides some basic org info. If for some reason you want to provide more info about the organization than that will handle, use the SchemaPersonOrgBase and just fill out the @id, to identify which organization is the hiring organization, then also fill out the Organization tag as well. Give the organization the same @id in both places and then fill out all the other information in the organization record. In other words, you don't need to provide all the organization fields in this object, just use this in combination with the existing organization object.

I'm not sure I'm explaining this well. See https://www.lullabot.com/articles/create-seo-juice-by-adding-json-ld-str... and scroll down to the heading "What about properties that reference other objects?". The "@id" is a way to provide a "reference" to another object that has more info. That's why "@id" has been added to all objects.

Needs to be re-rolled now that #2900164: Add tests (D8) is in.
