This assertion is just plain wrong. REST is an architectural principle focused on providing APIs for web services, and Roy Fielding was quite vocal in making it extremely clear that there is nothing in REST that is HTTP-specific, let alone makes it tied to HTTP. REST is an architectural style that relied on the concept of resources, which should be linkable. That's it.

there is nothing http (or HTML) specific in REST, but REST itself is specific to the domain problem where http and HTML are used

[rumanator]

What domain problem is that? Communicating through a network?
