Harry,</FONT></SPAN></DIV>

<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>A
quick few thoughts.</FONT></SPAN></DIV>

size=4></FONT></SPAN> </DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>PSI is
NOT at all SOAP-specific (the WSDL could easily</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff
size=4>generate pure HTTP bindings), but PSI is RPC-style
and</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff
size=4>stateful (like all IETF, PWG, and vendor print
protocols),</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>which
is the exact opposite of REST.</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff
size=4></FONT></SPAN> </DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>From
my reading of REST descriptions, it appears REST</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>is
verb-poor and noun-rich and stateless. Neither PSI,</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>nor
any other real print protocol is stateless - and I can't</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff
size=4>imagine any easy transform to get there (or why you'd</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>want
to).</FONT></SPAN></DIV>

size=4></FONT></SPAN> </DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>Since
there is consistency in available descriptions of</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff size=4>REST,
designing RESTful applications seems to be a</FONT></SPAN></DIV>
<DIV><SPAN class=328434822-08012007><FONT face=Arial color=#0000ff
size=4>statement in the eye of the beholder.</FONT></SPAN></DIV>

you care to expand on the reason for your</FONT></SPAN></DIV>
