Agenda
- charter
- weekly meeting schedule
- DDC model
- drafts

==========
Charter  
- version 00 circulated on the mailing list

John presenting charter
- disagree with Juergen comments on the charter
- 2nd and 3rd paragraphs are key
- IETF has concerns about proliferation of yang models
- the idea is to do generic information and data model, independent of platform, language, … i.e. it could be implemented in MIB, YANG or else…
- then after generic model, define a VPN management model, to build a a VPN network service use case, not knowing the exact topology of the network
- it is a policy model

Marc: 
- my understanding of Juergen comment is the discrepancy between 3rd paragraph and work items, where 3rd paragraph says: « 1) general network topology model » and work item says « yang models focused on VPN management » and « may include … »
- my guess on the IETF IESG reorg/opsdir on yang work is that they may be looking into how to map the yang work in various places. Maybe it is the time to talk to Benoît about SUPA place in this, specially the generic topology models.

John:
- make sense. will look into modifying the charter accordingly
- knows Benoît very well.
- action item on me to talk to Benoît Claise

Georgios:
- John to reach also to Juergen 

Marie-Jose Montpetit
- comment from Scott Bradner? what should we be doing with it?

Tina
