Re: [netmod] NETMOD WG Virtual Interim Meeting: 22 February 2016

[Kent Watsen]

Thank you all who joined today’s virtual interim meeting.

Other than my starting the recording late and rearranging the presentation 
order, I thought that the meeting went really well in that there seems to be a 
lot of support for trying to solve this problem, and because we have a plan to 
try to move towards having a WG document in the BA timeframe.  The plan is for 
draft-bjorklund-netmod-structural-mount to be updated based on the meeting and 
for it to be discussed on list as the basis for the WG effort on the topic.

Attached are the very rough Ethernet minutes captured during the meeting.  
Please review carefully.  Corrections can be made on the etherpad here: 
http://etherpad.tools.ietf.org:9000/p/netmod-interim-20160222  (so we can track 
changes, the end of meeting snapshot is here: 
http://etherpad.tools.ietf.org:9000/p/netmod-interim-20160222/timeslider#3933)

Hi,

I have posted a new version of the structural mount draft.  It hasn't
changed technically, but it uses a current version of
ietf-yang-library, clarifies some things and has some expanded
examples.

Same in YSDL.

It's also similar in YSDL. Augments apply only within a single schema,
which is essentially what we have now.

In YSDL one would need to be able to specify "/" as the root node for
the "mounted" schema. It's not allowed in -00 but it might be a useful
extension. I don't see any reason why it shouldn't work.

Currently this is not possible.  If you want to use such a mechanism
to mount selected subtrees from a module, it is not clear that this
will work - there might be references from subtree A to subtree B, so
if subtree B is not mounted, it is unclear how such references should
be handled.

> module)? 

If the augmenting module it not mounted, nothing happens - it is just
not there.  If the augmenting module is also mounted, it will be
augment the mounted module.  For example, suppose ietf-interfaces and
ietf-ip are both mounted at /foo.  The resulting tree would be:

  +--rw foo
 +--rw if:interfaces
+--rw if:interface* [name]
   ...
   +--rw ip:ipv4!

The system exposes all "top-level" modules as usual - just list them
in the top-level YANG library.
