Plone already had this rfc822 style in back in old archetypes 
marshallers. I never liked it. It was clumsy to handle

I like the base idea behind: Add additional information to the schema 
where needed an use it to serialize it. The same is possible with 
deserialization.

I dont think rfc822 headers are what we want to have. In json there are 
better suited structures around. It would end up in a text-block 
packaged in json, the client has to parse the text block again. Too much.

For sure is json-ld a possible one (and it would add other benefits). 
json-ld is (as rfc822 too) in fact more about exchanging metadata than 
about serialization of content.
json-ld as payload for deserialization might work too. But we may need a 
container format around, for the binary data and other payloads not 
considered to be metadata.
