Hello,

We
have uploaded an Internet draft about data modeling for
network
management. It can be found here:

http://www.ietf.org/internet-drafts/draft-xiao-evaluate-dml-00.txt

We are Debao Xiao and Hui Xu. Debao Xiao is a professor at

Institute of Computer Network and Communication, HuaZhong
Normal
University (www.ccnu.edu.cn) and Hui
Xu is his doctor
candidate. Professor Xiao has many years of
experience
in the area of network management and we are now working in

a research project (funded by both the key scientific and

technological project of Wuhan city in P. R. China and
the key
scientific and technological project of Hubei province
in P.R. China)
about next generation network management and
security management.

In some scenarios, the multiplicity of network management
models
implies the use of multiple management data modeling languages,

which model the resources to be managed. Each language differs in

the level of various capabilities and expressiveness, most of
which
are not easily measured. One of the activities in this project
has then
been to address the problem about how to establish a
framework of
evaluation to compare different management data modeling
languages
based on a set of criteria.

Another aim of our project is to prospect the essentail
features of
future data modeling language based on proposed framework
of evaluation,
since existing ones have drawbacks of different levels,
which hinder
them in adapting to the requirements of next generation
network management.

We have demonstrated the most important part of our proposed
criteria in
this draft, which are modeling approaches, expressiveness,
readability,
interoperability, extensibility and others, and have also
presented some
perspectives on developing future data modeling
languages for next
generation network management, possibly integrating
existing ones. The
characteristics of existing data modeling languages
are then summarized
through comparison based on given criteria for
evaluation.

We hope our work can contribute to any future work
on
data modeling for next generation network management.

If there is significant interest, we would be happy to
give
a presentation of this Internet draft in Wuhan, P. R.
China.

Best
regards,
Debao Xiao and Hui Xu
