Maopeng Zhang - Could the author provide the rule coming from or reason why we regard it as a guideline?  I agree with Alex that basically we should  TOSCA guidelines if the data model is used by TOSCA. 

Lingli Deng - Suggest to keep it out, if no clarifications is agreed.

7-  When defining new Namespace, in order to avoid namespaces and types name types definitions collision, it is recommended that ONAP uses the rule and guidelines as described in the OASIS TOSCA Simple YAML Profile v1.2.

...

Alexander Vul - GENERAL OBSERVATION - we have three modeling domains in play for ONAP - development time, design time and run time. It would be good to establish some ground rules in terms of what IMs and what DM encodings are applicable at what "time". For example, are we implying that TOSCA data models are used across all three modeling domains? if not, then are there any principles and/or guidelines that establish what starting points and best practices are to be used within each domain?

Lingli Deng - My understanding, we will have IM for design time and run time. We will have UML representation for both times. We will have TOSCA representation for information exchanges across times or across modules whenever needed.
