Description

At present there can be only one data MIME for the every request/stream on the connection. This is negotiated in the SETUP frame. The Stream Data MIME Types Metadata Extension defines a way to declare the data MIME type for a specific request/stream. This includes a MIME type for the request input and an "acceptable" MIME type for the response.

Research direction

Start by tracing how RSocket SETUP negotiation determines the connection-wide data MIME type and how request or stream metadata is handled. Read the linked Stream Data MIME Types Metadata Extension, then identify the relevant Java implementation and tests; done means requests can declare input and acceptable response MIME types per stream according to that specification.
