Re: Combining Linked Data HTTP URIs and HTML5 WebSocket URIs

The problem I am having coming to terms with your question is that the
web socket protocol is "full custom" once the two endpoints have
established that they are indeed using web sockets.

The http protocol defines all kinds of details that continue from
connection through disconnection (e.g. what kind of data is being
exchanged).

This seems kind of like designing for a gate array (http) vs. a full
custom IC. That's probably what you expect, and that's fine - it's
just you've created an ASIC -- an Application-Specific Integrated
Circuit.

And so along the lines of what Kingsley wrote in his response, it
seems to me you could:

* Design a vocabulary for describing servers and performance metrics
using any URL scheme.

* Design (at least) two access mechanisms, one based on http and the
other based on web sockets. Clients of the latter would just have to
understand your application-specific protocol designed to transmit web
socket data frames to be formatted and parsed as you see fit.

Either access mechanism could be used to communicate (subsets of) the
same graph.

Potentially confused, I am...
