I'm badly behind on this BIG news -- BMC, Fujitsu, HP, and IBM are collaborating on a new CMDB spec. It's a bit of a blow to DCML and with IBM's participation one hopes that the OMG stack will be used as its foundational basis -- hard to avoid given that IBM seems to see Eclipse as the solution for everything, and Eclipse has a standard OMG mapping in the Essential MOF .
Updated 5/24. I have some inkling that (like DCML) the Semantic Web is being considered for this. If this is the case, I concede my opposition - have been reading further and the Semantic Web does make some sense in terms of value-add for this problem domain. Still concerned about where I'm going to get knowledgeable folks to build solutions based on this standard.
