For me, its basically to add support for metadata in REST, by using things like JSON-LD to describe the layout of data and be competitive with what GraphQL is offering. Of course there are a common definition for data and metadata, trying to define a common standard. It's funny how in the end this will end into reinvent a thing like protobuf, but in JSON, much more verbose, and that can't be read by a human anyway. GraphQL at least do all this while being human-friendly and allowing to define whats needed 'by hand' or by a machine. (But i also dont think this is a great thing to use if the communication is internal and M2M anyway, but its a great solution to serve some api to a bigger crowd of heterogeneous clients)
