(kwatsen, 14:26:03)

* LINK: http://tools.ietf.org/html/draft-wildes-netmod-syslog-model-03
(Clyde, 14:34:25)
* ill issue a call for adoption of the syslog model shortly
(Thomas__, 14:44:09)
* Call-in User_7 (Alex Clemm?) asks about support for structured data
(kwatsen, 14:45:38)
* kwatsen asks and is assured that other encodings beyond
structured-data can be added in the future (kwatsen, 14:50:24)
* github link for ACL model discussed earlier:
https://github.com/YangModels/yang/blob/master/experimental/ietf/ACL-MODEL/draft-bogdanovic-netmod-acl-model-02.txt
(Thomas__, 14:50:45)
* calls for adoption of the draft as a NETMOD WG draft (Thomas__,
14:53:06)
* Latest SYSLOG model posted too:
https://github.com/YangModels/yang/blob/master/experimental/ietf/SYSLOG-MODEL/draft-wildes-netmod-syslog-model-03.txt
(Thomas__, 14:54:43)
* confirmed Call-in User_7 is Alex (kwatsen, 14:55:15)
* - lads asks if this should be in net mod if syslog is closed
(Thomas__, 14:56:56)
* Lada questions if another WG should do this work. Benoit notes that
syslog WG is concluded. (kwatsen, 14:57:11)
* - benoit is ok to do these in net mod if there are no other homes
for this (Thomas__, 14:57:25)
* Benoit points out that there are requests for many models for which
there are no homes, and creation of a WG per model wouldn't scale
(kwatsen, 15:00:42)
* one suggestion is to have one WG focused on models and another on
the language (kwatsen, 15:01:26)
* schoenw recommends that we get data models done and deal with
scalability issues once we reach the boundaries (kwatsen, 15:04:12)
* Thomas__ agrees (kwatsen, 15:04:31)
* Thomas__ recommends we incubate more Yang Doctors as a means to
scale modeling work (kwatsen, 15:06:08)
* : Kent, I have increase the number of YANG doctors recently.
(Benoit__, 15:06:32)

* @EricVoit, and running code in ODL (Benoit__, 15:14:06)
* question regarding impact on device - does if have to implement
pub/sub and async notification? (kwatsen, 15:28:32)
* Alex explains that there are two roles: mount client and mount
server (kwatsen, 15:29:04)
* the mount server may support the ability for async notifications
(kwatsen, 15:29:40)
* Benoit asks if there is an advantage to this approach over existing
protocols (VRRP) (kwatsen, 15:30:48)
* Benoit__ asks if this is really an extension of YANG (no, it can be
implemented with existing Yang 1.0) (kwatsen, 15:47:35)
* Balazs questions if the protocol extensions should be brought to the
NETCONF WG (kwatsen, 15:48:43)
* Alex explains that this can be implemented on top of existing
NETCONF. NETCONF extensions (pub/sub) would be in a different draft
(kwatsen, 15:49:37)
* Eric notes that NETCONF is not required. Other protocols (HTTP)
were tried as well (kwatsen, 15:53:19)
