Prior discussion pointed out that:

• a private repository is not the appropriate place for the items since not everyone has access to this
• the ONF GitHub is publicly available but not all participants are allowed to contribute to it
• there is no single ONF repository which could host such Issues; IISOMI is spread over many repositories
• it might be possible to cover the discussions in Wiki pages
• new discussions should be captured in the Meeting Minutes and then copied to the Wiki pages
• Bernd Zeuner 08 Oct 2021 Draft an example Wiki page that capture an discussion item

Proposal wiki page from Bernd for capturing discussion items:

from OIMT

CoreModel FD - to of the tree

Composed FC-Switch .... with no sense if independent

.

Driver of Model structure (arrangement)

usage of stereo-types

• aggregate
• leaf
• admin relationships
• Chris has nice ideas - but needs to be further analyzed.

First try of "modelling profiles" on CoreModel

Target:

• Split CoreModel in "smaller" parts - decoupling 
• Rules needs to be described/defined/documented.

Further details:

• https://wiki.opennetworking.org/download/attachments/266141701/ONF_T64_DddAggregates.pptx?api=v2
