Thank you for the feedback.

As I said, I wish I had more time to research this topic properly and
write up a summary. I knew about JSON-LD but it did not come to my
mind when I wrote my email.

JSON-LD <http://www.w3.org/TR/json-ld/> is now a W3C recommendation,
but I have been seeing it as a way to publish data.

The presentation I was citing was using HAL to describe an API using
hypermedia. Basically, you get data *and* links to
create/update/delete related data. Knowing the root url (entry point)
and the vocabulary used to describe the data/actions in that domain
you just crawl your way through and will never need to build urls
after reading the documentation for the API (see REST in Roy
Fielding's thesis).

I have not (yet) read all the references mentionned in the first
answer on reddit. Would they explain how JSON-LD is related to
hypermedia APIs and not just publishing linked data as JSON?
