[Nml-wg] [Fwd: [Nsi-wg] Notes from call 6-24]

[Jeroen van der Ham]

Hello,

Below are some points that were raised during an NSI conference call 
yesterday. I don't remember the details, but I believe we have had 
discussions on identifiers and how to relate these to domains. I also 
believe that this is more of an NML than an NSI issue.

Also note that Topology Aggregation/Abstraction is being discussed in 
the NSI, and I believe that our schema should also account for that.

Jeroen.
