Without getting into the merits/demerits of DCML,
I don't think I would categorize DCML into the set of IPMI, HPI etc or SNMP

DCML is not a protocol like SNMP or HTTP but it is simply like any other
markup language
(SyncML, HTML, XML or WML) defining the grammar to represent the
and use some other related protocols (such as HTTP, WSP) to transfer that
across the network. These two (mark up language and the protocols) are, I
consider them, separate.

"Data Center Markup Language".... oh, man, looks like yet another mechanism
for modeling a system (including operating system and hardware.)

Lets see... we have (in no particular order):
* SNMP (with MIBs for everything from IPv6 to a candy machine)
* CIM (Including WBEM which also has an XML grammer)
* HPI (which will probobly have to provide a remote protocol in the next
* IPMI (with it's IPMI LAN protocol)
* What was the Microsoft XMLish modeling technology?
 ... and now ...

Am I forgeting anything? It would be nice to put all of these techologies
in perspective in the 3.0 spec.  DCL should also have the same view of the
universe (even if the recommendation on which technology to use is


* Build a grammer, and solution will come
