I agree with John. The mapping of an information model to a data model has
its own chalenges and the chalenges will be different from one technology to
an other. That does not mean that we have to revisit the model each time.
 
I am not trying to say that PCIMe is perfect and that it should never be
revisited, but I do not see (so far) enough reasons for re-opening such
discussions. 
 
Regards,
Mircea.

I fundamentally disagree with rebuilding RFC 3460, which is an INFORMATION
MODEL, because of DATA MODEL concerns. That is exactly backwards, because it
ensures that the information model cannot be mapped to other types of data
models.

PCIMe is at Proposed Standard. If, for example because of this effort to try
and MAP it onto LDAP, we

find that we did some things in PCIMe that we should not have done, then,
with WG consensus,

we can make incompatible changes to PCIMe and then recycle at Proposed
Standard.

That is part of the normal standars track process. That is, we get something
to PS, then we start

using/implementing (the "using" part is reusing PCIMe definitions in otehr
CIM docs (like the

other docs we did in Policy, and like the IPsec work, the "implementing" is
sort of mapping onto for 

example LDAP I think)... and if we find major issues, then we fix and
recycle at PS. If we do not

find major issues, we may advance to DS.

 

Hope this helps.

Bert
