Well, kind of.  There are a whole lot of coordination languages out
there, but only one is "RESTful"; the one whose coordination semantics
are applicable to all things with identity.  But each of them shares the
same desirable property of visibility (via late binding), since the
agreement to communicate is also an agreement to coordinate.  This is
in contrast to the typical use of SOAP where the communication agreement
is just an agreement to send bits.

The Wiki page you're probably referring to is;


which is pretty raw.  I just created it as placeholder to capture what I
felt was an important point; that application protocols are coordination

BTW, it's also interesting to note that David Gelernter basically
predicted the Web in his book MirrorWorlds (the first page, even),
and most of his research at that time was around coordination
languages, in particular Linda, which shares similar goals (and
coordination semantics) to the Web.  It just wasn't as well designed.
