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
