Abstract:
   This document defines YANG packages, a versioned organizational
   structure holding a set of related YANG modules that collectively
   define a YANG schema.  It describes how packages: are represented on
   a server, can be defined in offline YANG instance data files, and can
   be used to define the schema associated with YANG instance data
   files.

        Title           : YANG Schema Comparison
        Author          : Robert Wilton
	Filename        : draft-ietf-netmod-yang-schema-comparison-01.txt
	Pages           : 13
	Date            : 2020-11-01

Abstract:
   This document specifies an algorithm for comparing two revisions of a
   YANG schema to determine the scope of changes, and a list of changes,
   between the revisions.  The output of the algorithm can be used to
   help select an appropriate revision-label or YANG semantic version
   number for a new revision.  This document defines a YANG extension
   that provides YANG annotations to help the tool accurately determine
   the scope of changes between two revisions.

This is only a reference fix and bump to unexpire it.  Recent work has been=
 focused on YANG packages and semver for the most part.

Part 2, unfortunately my original email (attached) was truncated somewhere =
along the way ...

The remainder of my comments are:


Suggest adding an example ", e.g., <operational>."

       o  filter-spec: This is a choice between different filter constructs
          to identify the portions of the datastore to be retrieved.  It
          acts as a node selector that specifies which data nodes are withi=
n
          the scope of the comparison and which nodes are outside the scope=
.
          This allows a comparison operation to be applied only to a
          specific portion of the datastore that is of interest, such as a
          particular subtree.  (The filter dow not contain expressions that
          would match values data nodes, as this is not required by most us=
e
          cases and would complicate the scheme, from implementation to
          dealing with race conditions.)
         =20
Perhaps "parts/part" rather than "portions/portion".

Suggest rewording the last sentence to:

    Note, the filter does not allow expressions that match against data nod=
e values since that may incur implementation difficulties and is not requir=
ed for normal use cases.


       o  ...  When the target datastore is <operational>, "origin"
          metadata is included as part of the patch.  Including origin
          metadata can help in some cases explain the cause of a difference=
,
          for example when a data node is part of <intended> but the origin
          of the same data node in <operational> is reported as "system".

I think that this test needs to refer back to the 'exclude-origin' or 'repo=
rt-origin' options since the origin metadata isn't always included.



    5.  YANG Data Model

        The key words 'MUST', 'MUST NOT', 'REQUIRED', 'SHALL', 'SHALL
        NOT', 'SHOULD', 'SHOULD NOT', 'RECOMMENDED', 'NOT RECOMMENDED',
        'MAY', and 'OPTIONAL' in this document are to be interpreted as
        described in BCP 14 (RFC 2119) (RFC 8174) when, and only when,
        they appear in all capitals, as shown here.
       =20
I couldn't see that RFC 2119 language is actually used in the YANG module, =
so perhaps this can be deleted?

         rpc compare {
           description
             "NMDA compare operation.";

Perhaps "NMDA datastore compare operation."

                 anydata source-value {
                   when "../operation =3D 'delete'"
                     + "or ../operation =3D 'merge'"
                     + "or ../operation =3D 'move'"
                     + "or ../operation =3D 'replace'"
                     + "or ../operation =3D 'remove'";
                   description
                     "The anydata 'value' is only used for 'delete',
                      'move', 'merge', 'replace', and 'remove'
                      operations.";
                     =20
I'm not convinced how useful the when statement really is in this case, sin=
ce 'source-value' isn't marked as mandatory, a server is allowed to omit it=
 when it doesn't apply anyway.

    6.  Example

       <operational> does not contain object "description" that is containe=
d
       in <intended>.  Another object, "enabled", has differences in values=
,
       being "true" in <operational> and "false" in <intended>.  A third
       object, "name", is the same in both cases.  The origin of the object=
s
       in <operational> is "learned", which may help explain the
       discrepancies.

I think that we should probably refrain from calling them objects, perhaps =

Hi,

Here is my AD review for draft-ietf-netmod-nmda-diff-07.  Apologies for the=
 delay.

Thank you for writing this document, I think that it is useful, and looks l=
ike it is in good shape.


Main comments:

1. Should there be any text about how to find out what datastores are suppo=
rted by a device?  E.g., pointing them to either YANG library, or protocol =
specific mechanisms in the case of RESTCONF.

2. It might be helpful to add a comment about potential issues that could a=
rise by comparing <running> to <operational>, i.e., additional differences =
could be reported due to inactive configuration and template processing bet=
ween <running> and <operational>.

3. I would prefer if 'exclude=3Dorigin' was in the reverse sense and perhap=
s called 'report-origin' instead.  With the reverse sense it seems to be sa=
fer if new datastores are defined, where otherwise the behaviour could end =
being under specified.

4. Should there be an option to filter on origin metadata?  E.g., only incl=
ude values that come from intended.  Otherwise, things like IP addresses le=
arned from DHCP may always turn up as differences.

5. I'm not that keen on the "Possible Future Extensions" section of an RFC.=
  Personally, I would prefer that this section is deleted, but if you wish =
to retain it, then please can you move it to an appendix.


I've also included some minor comments inline below, and some nits at the e=
nd:

    Abstract

       This document defines an RPC operation to compare management
       datastores that comply with the NMDA architecture.

The abstract is perhaps somewhat terse.  Perhaps:

    This document defines a YANG RPC operation to compare the
    contents of network management datastores that comply with
    the NMDA architecture and return the differences in the
    YANG-Patch format.


    1.  Introduction

       The revised Network Management Datastore Architecture (NMDA)
       [RFC8342] introduces a set of new datastores that each hold YANG-
       defined data [RFC7950] and represent a different "viewpoint" on the
       data that is maintained by a server.  New YANG datastores that are
       introduced include <intended>, which contains validated configuratio=
n
       data that a client application intends to be in effect, and
       <operational>, which contains at least conceptually operational stat=
e
       data (such as statistics) as well as configuration data that is
       actually in effect.

I would suggest deleting "at least conceptually", since the <operational>
datastore does contain all operational state, but it may be implemented as =
a virtual construct that spans multiple nodes (e.g., linecards) and process=
es.


       NMDA introduces in effect a concept of "lifecycle" for management
       data, allowing to clearly distinguish between data that is part of a
       configuration that was supplied by a user, configuration data that
       has actually been successfully applied and that is part of the
       operational state, and overall operational state that includes both
       applied configuration data as well as status and statistics.

"allowing to clearly distinguish" =3D> distinguishing"
"status and statistics" =3D> "status information and statistics"


       As a result, data from the same management model can be reflected in
       multiple datastores.  Clients need to specify the target datastore t=
o
       be specific about which viewpoint of the data they want to access.
       This way, an application can differentiate whether they are (for
       example) interested in the configuration that has been applied and i=
s
       actually in effect, or in the configuration that was supplied by a
       client and that is supposed to be in effect.

Perhaps reword the last sentence to match the logical data flow in the serv=
er:

   For example, a client application can differentiate whether they are
   interested in the configuration supplied to a server and that is
   supposed to be in effect, or the configuration that has been applied and=
 is
   actually in effect on the server.


       When configuration that is in effect is different from configuration
       that was applied, many issues can result.  It becomes more difficult
       to operate the network properly due to limited visibility of actual
       status which makes it more difficult to analyze and understand what
       is going on in the network.  Services may be negatively affected (fo=
r
       example, breaking a service instance resulting in service is not
       properly delivered to a customer) and network resources be
       misallocated.

Perhaps change "actual status" to "actual operational status".

I also suggest changing the last sentence to:

    Services may be negatively affected (e.g., degrading or breaking a cust=
omer service) or network resources may be misallocated.


        3. Definitions:

It should probably define that <intended>, <operational>, (and perhaps <run=
ning>) are used to indicate names of datastores.

It should also explain that <compare> is used as the name of a YANG RPC.


    4.  Data Model Overview

       At the core of the solution is a new management operation, <compare>=
,
       that allows to compare two datastores for the same data.

Suggest rewording this first sentence to:

  The core of the solution is a new management operation, <compare>,
  that compares the data tree contents of two datastores.

       o  target: The target identifies the datastore to compare against th=
e
          source.

Suggest adding an example ", e.g., <operational>."

       o  filter-spec: This is a choice between different filter constructs
          to identify the portions of the datastore to be retrieved.  It
          acts as a node selector that specifies which data nodes are withi=
n
          the scope of the comparison and which nodes are outside the scope=
.
          This allows a comparison operation to be applied only to a
          specific portion of the datastore that is of interest, such as a
          particular subtree.  (The filter dow not contain expressions that
          would match values data nodes, as this is not required by most us=
e
          cases and would complicate the scheme, from implementation to
          dealing with race conditions.)

Perhaps "parts/part" rather than "portions/portion".

Suggest rewording the last sentence to:

    Note, the filter does not allow expressions that match against data nod=
e values since that may incur implementation difficulties and is not requir=
ed for normal use cases.


       o  ...  When the target datastore is <operational>, "origin"
          metadata is included as part of the patch.  Including origin
          metadata can help in some cases explain the cause of a difference=
,
          for example when a data node is part of <intended> but the origin
          of the same data node in <operational> is reported as "system".

I think that this test needs to refer back to the 'exclude-origin' or 'repo=
rt-origin' options since the origin metadata isn't always included.



    5.  YANG Data Model

        The key words 'MUST', 'MUST NOT', 'REQUIRED', 'SHALL', 'SHALL
        NOT', 'SHOULD', 'SHOULD NOT', 'RECOMMENDED', 'NOT RECOMMENDED',
        'MAY', and 'OPTIONAL' in this document are to be interpreted as
        described in BCP 14 (RFC 2119) (RFC 8174) when, and only when,
        they appear in all capitals, as shown here.

I couldn't see that RFC 2119 language is actually used in the YANG module, =
so perhaps this can be deleted?

         rpc compare {
           description
             "NMDA compare operation.";

Perhaps "NMDA datastore compare operation."

                 anydata source-value {
                   when "../operation =3D 'delete'"
                     + "or ../operation =3D 'merge'"
                     + "or ../operation =3D 'move'"
                     + "or ../operation =3D 'replace'"
                     + "or ../operation =3D 'remove'";
                   description
                     "The anydata 'value' is only used for 'delete',
                      'move', 'merge', 'replace', and 'remove'
                      operations.";

I'm not convinced how useful the when statement really is in this case, sin=
ce 'source-value' isn't marked as mandatory, a server is allowed to omit it=
 when it doesn't apply anyway.

    6.  Example

       <operational> does not contain object "description" that is containe=
d
       in <intended>.  Another object, "enabled", has differences in values=
,
       being "true" in <operational> and "false" in <intended>.  A third
       object, "name", is the same in both cases.  The origin of the object=
s
       in <operational> is "learned", which may help explain the
       discrepancies.

I think that we should probably refrain from calling them objects, perhaps =
"leaf instance" would be better?  Rather than "differences in values", perh=
aps "different values".

E.g.,

       <operational> does not contain an instance for leaf "description" th=
at
       is contained in <intended>.  Another leaf, "enabled", has different
       values in the two datastores, being "true" in <operational> and
       "false" in <intended>.  A third leaf, "name", has the same instance
       value in both datastores.  The origin of the leaf instances in
       <operational> is "learned", which may help explain the discrepancies=
.

       <enabled>true</enabled>

       </interface>
   </interfaces>

There is an extra line, and dodgy indentation for "</interface>".

*        Not all errors can be detected at configuration time. Error that o=
ccur while ECA logic is being evaluated will cause the server to generate a=
n eca-exception notification.
-      Q1:Does an exception cause the ECA entry to be disabled automaticall=
y?
-      Q2: What else exceptions and details parameters need to be defined?
*        Proposal to Q1:
-      In case of one time ECA, it will generate exception notification, st=
op executing other actions associated with the same event, exit ECA executi=
on process
-      In case of periodical ECA execution, it will generate exception noti=
fication, stop executing other action associated with the same event, exit =
ECA execution process in the current period, move to the next period, if th=
e same exception is generated, the ECA entry will be disabled, send another=
 exception notification;

*        Proposal to Q2:

-      The action can be executed in the form of RPC function or function c=
all, therefore function invoke error, rpc invoke error should be defined, i=
n addition, we may allow bind policy variable with xpath expression, variab=
le binding unknown should be defined to cover exception case. When ECA entr=
y can be disabled, the corresponding notification can be generated, we can =
call it eca entry disable exception.

*        Q1: How different ECAs do not impact each other if they share PVs?

*        In the current ECA model, Event, Condition and Action are defined =
separately and ECAs comprise of a set of ECA entries, each ECA entry have o=
ne Event, a set of condition-action entries. Each condition-action entry ha=
ve a set of conditions, one action entry; each action entry have multiple a=
ction items.

*        ECA interacts with another ECA (i.e., two ECAs have different data=
 source) hasn't been covered yet.

*        Proposal:

Not sure this is the right question, since PV are shared by multiple ECA in=
stances, ECA instance execution can lead to the PV state changes. If we don=
't want to see different ECA impact each other, we should not define shared=
 PV or global PV for them, instead, the local PV associated with a specific=
 ECA instance should be defined separately.

*        How can ECA access specific datastores?
-      Currently no NMDA support for config=3Dtrue values in <operational> =
is provided.
-      Access to <candidate> datastore is not possible.
*        Proposal:
In the current ECA model draft, we most focus on self monitoring case, only=
 config-false values are targeted.
However since we allow network management function being moved to the serve=
r as local client, why the local client can not access specific datastore i=
n the same way as remote client or the network management system?

*        Diagnostic Event is a user interface<https://en.wikipedia.org/wiki=
/User_interface> implemented in the server which allow user to view and/or =
manipulate the ECA logic 's internal state for the purpose of debugging<htt=
ps://en.wikipedia.org/wiki/Debugging>.
*        Diagnostic Test provides health check on ECA logic and the ECA XPa=
th function library, e.g., allow user to trigger start action, stop action =
or next action execution step by step.
Proposal:  Add diagnostic event support and start, stop, next action are de=
signed for diagnostic event.

Content-Type: text/plain; charset="us-ascii"

We started by discussing prep of material for the upcoming IETF109 meetings=
:

Slide Prep:
- Update on Versioning - Reshad
- Update on Semver - Joe ?
- Update on Packages
     - what has changed/progressed - Bo
              - open issues - Jason
- General update on weekly Versioning calls - Jan
   - tried to progress Versioning, but a bit stuck
   - bumped the comparison & versioning selection drafts, updated to newest=
 RFC format xml2rfc v3
   - spent lots of time on packages, lots left to go
   - focus is on Packages, likely for the next while

Presenting at IETF109:
- Bo for Packages
- Jan for the rest

Some issues to make sure we cover in the slides:
- whitespaces  <- Reshad
- NBC and imports <- Reshad
- pre-release semver ?  <- Joe
- gaps in revision label, removing history  <- Reshad

Then the rest of the meeting was discussing how schema mounts should work w=
ith packages.
- a package includes schema mount points, but TBD if it includes informatio=
n about what gets mounted at those mount points (minimum sets, other packag=
es, etc)
- we also discussed definitions of "package schema", "datastore schema" and=
 whether those include mounted schema or not

Hi,

We are a little confused when reading RFC8808 (reset to factory-default dat=
astore) in relation to the "system configuration" source in figure 2 of RFC=
8342.  When correctly understanding RFC 8342, the running datastore is empt=
y when the system starts up after coming from the factory, and 'factory def=
ault' data is entered in the operational datastore as 'system/default confi=
guration' data.

RFC 8808 seems to suggest that the running datastore contains (factory-defa=
ult, system) data when the system starts up after coming from the factory. =
I.e. the understanding is that a reset to factory default brings the system=
 back to the status as if it comes from the factory, and it is said the fac=
tory default goes into the running, ...

What exactly is the content of the running datastore when it comes from the=
 factory?
Could this be clarified?

Regards, Bart

I consider RFC 8808 an extension that people may implement if their
systems do what RFC 8808 describes, namely that the running datastore
is bootstrapped from a factory default datastore. (Of course, a system
with an empty running datastore after a factory reset may claim to be
bootstrapped from an empty factory default datastore.)

In other words, I think the answer to "What exactly is the content of
the running datastore when it comes from the factory?" is that it is
empty. On first boot, on a system implementing RFC 8808, it would be
loaded with the content of the factory default datastore and on
systems not implementing RFC 8808 it would most likely remain empty.

As people do more YANG modules, more and more logic and description moves
from regular text into the YANG module.  Where it is awkward and annoying to
edit.

And references from YANG modules don't get counted/resolved/updated, and
all sorts things that the XML format was designed to solve have basically
reverted to 1996 era (without even nroff) when it comes text in the YANG mo=
dule.

In one of my drafts, I guess some minor wording tweaks in one draft leads to
some lines exceeding 72 characters (by one). Argh. Change from C-mode to
text-mode. reflow.

It seems like we should be thinking about what to do here.
I was introduced to the SED method of fixing yang YYYYMMDD version
references.

While I like YANG as executable "code", it sure feels like it is not smart =
to
be authoring in it.

Yes, turns out I already have used this, but forgot I had it.
I don't see anything that helps.
M-q reflowed a paragraph, but made it too long with 76 columns wide.

And that still doesn't help get the references in the description right.

Is your .emacs setting fill-column to a non-standard value?

C-x f 69 RET

or put

// -*- fill-column: 69 -*-

into the first line of your YANG file (in a comment)
or better

(add-hook 'yang-mode-hook
	  '(lambda () (set-fill-column 69)))

in your .emacs.

Hi,

my solution that I've been using for years is to write YANG modules in the =
YIN syntax. With the nXML mode of emacs this is actually rather effective (=
statement completion, on-the-fly validation).

I also extended the YIN syntax with a few XML elements from the XHTML names=
pace. This helps me to handle paragraphs and lists in a safe way.

Descriptions etc. are then reflowed automatically as a part of XSLT transfo=
rm to the compact YANG syntax.

Here are the details:

I ensured that I have the latest version of the Emacs YANG mode, and find
that M-q works well to wrap description strings, but...

   1. Should I expect intelligent behaviour of RET and TAB when within a
   description (or other) string? I find that (in this context) RET positio=
ns
   the cursor at the start of the line, and TAB does nothing. Ideally RET
   might position the cursor at the indentation point of the previous line,=
 or
   one character past the opening quote if this was the first line.
   2. Wrapping (quite reasonably) can't handle cases where the author
   didn't in fact intend line breaks to be inserted. The most common cases =
are
   probably (a) not using a blank line as a paragraph break, (b) text was
   further indented (which often implies literal text), or (c) text started
   with * (or -, ...) and was to be interpreted as a list item.

I don't believe that RFCs 7950 and 8407 say anything about paragraph
formatting, but most NETMOD YANG does seem to adhere to the convention that
paragraphs should be separated by blank lines. Perhaps this could be made
into a stronger convention?

As for the other cases (further indentation -> literal, and */- mean list
items), of course this is getting back to the markdown discussion. I
believe that when this has come up before the discussion has died for want
of clear standards. However I do believe that it would be very useful to
define some layout conventions (or rules) that allow automated reflow and
other formatting, and personally I would take it further than just the
three points that I have mentioned! It doesn't have to be called
'markdown'...

Subject: Re: [netmod] [Tools-discuss] reflow of YANG descriptions, and gene=
ral YANG format annoyances=0A=
=0A=
I ensured that I have the latest version of the Emacs YANG mode, and find t=
hat M-q works well to wrap description strings, but...=0A=
=0A=
  1.  Should I expect intelligent behaviour of RET and TAB when within a de=
scription (or other) string? I find that (in this context) RET positions th=
e cursor at the start of the line, and TAB does nothing. Ideally RET might =
position the cursor at the indentation point of the previous line, or one c=
haracter past the opening quote if this was the first line.=0A=
  2.  Wrapping (quite reasonably) can't handle cases where the author didn'=
t in fact intend line breaks to be inserted. The most common cases are prob=
ably (a) not using a blank line as a paragraph break, (b) text was further =
indented (which often implies literal text), or (c) text started with * (or=
 -, ...) and was to be interpreted as a list item.=0A=
=0A=
I don't believe that RFCs 7950 and 8407 say anything about paragraph format=
ting, but most NETMOD YANG does seem to adhere to the convention that parag=
raphs should be separated by blank lines. Perhaps this could be made into a=
 stronger convention?=0A=
=0A=
As for the other cases (further indentation -> literal, and */- mean list i=
tems), of course this is getting back to the markdown discussion. I believe=
 that when this has come up before the discussion has died for want of clea=
r standards. However I do believe that it would be very useful to define so=
me layout conventions (or rules) that allow automated reflow and other form=
atting, and personally I would take it further than just the three points t=
hat I have mentioned! It doesn't have to be called 'markdown'...=0A=
=0A=
<tp>=0A=
In the category of general annoyance, rather than the points above, the IET=
F has abolished the page number.  Look at recent RFC and pagination has van=
ished.  The justification is that RFC are now available in different format=
 and that page numbers are not consistent across the format so they must be=
 eliminated.=0A=
=0A=
This came up on RFC Interest and I asked how to reference a piece of text a=
nd was told that you include lots of section numbers.  I asked about 50-pag=
e YANG modules with no sections but this is a requirement that has escaped =
the tool-makers.  One suggestion was to include lots of numbered sub-headin=
gs, another to include separate sourcecode elements with an anchor for each=
.=0A=
One passing comment was that with v3 xml the extraction code should not be =
needed any more.  I do not understand but expect that there will be interes=
ting times.=0A=

I don't know what the plan is, but in the recent survey on IETF authoring t=
ools, I suggested the option of including YANG modules in xml2rfc sources a=
s foreign-namespace blocks in the YIN format. This could solve most of thes=
e issues and, in particular, allow for safely reflowing text in description=
s etc. along with the rest of the RFC.

Regarding markup inside description/contact/reference/error-message, I thin=
k XML is in fact still the best option. Light-weight choices such as markdo=
wn are too brittle for these purposes.

Once you have the XML for the RFC:
See https://tools.ietf.org/html/rfc8152#page-7
for the right way to do this.

Dear participants of netmod WG,



Would it be interesting (?) if I update the next draft=C2=A0https://tools.i=
etf.org/html/draft-shytyi-netmod-vysm-02=C2=A0with:=C2=A0



   o  ieee-dot1Q-types
   o  ietf-interfaces
   o  ietf-ip
   o  ietf-logical-network-element
   o  ietf-network
   o  ietf-network-instance
   o  ietf-ietf-network-topology
   o  ietf-routing-types
   o  ietf-te-topology
   o  ietf-te-topology-sf=20

   o  ietf-te-types
   o  ietf-yang-schema-mount
   o  The YANG modules introduced in this document:
      *  ietf-ucpe-lne-properties
      *  ietf-ucpe-lt-virtual-link-id
      *  ietf-ucpe-ni-properties
      *  ietf-ucpe-node-type



All compatible modules and schema is presented in the github repository=C2=
=A0https://github.com/dmytroshytyi/ucpe-ietf





+ @Mahesh=C2=A0

=C2=A0 =C2=A0 After interesting disscution I tend to add=C2=A0 the deviatio=
n of these yang models (https://github.com/dmytroshytyi/ucpe-ietf/blob/mast=
er/submodules/etsi-nfv-vnf-deviation.yang) and (https://github.com/dmytrosh=
ytyi/ucpe-ietf/blob/master/submodules/etsi-nfv-common-deviation.yang) + mak=
e a leafref "vnfd" under=C2=A0"/lne:logical-network-elements/lne:logical-ne=
twork-element/logical-network-element-properties/". You migth find the deta=
ils in the github repo above.

=C2=A0 =C2=A0 =C2=A0About these modules: If my approach to add these yang m=
odules (with small modification described below) seems incorrect, may you p=
lease suggest how can I integrate them in the existing set of yang modules?



mofidification of https://github.com/dmytroshytyi/ucpe-ietf/blob/master/sub=
modules/etsi-nfv-common-deviation.yang

submodule etsi-nfv-common-deviation {




yang-version 1.1;









//DEVIATION BEGIN;




belongs-to ietf-ucpe-lne-properties {




prefix ucpe;




}




//DEVIATION END;




mofidification of=C2=A0=C2=A0https://github.com/dmytroshytyi/ucpe-ietf/blob=
/master/submodules/etsi-nfv-vnf-deviation.yang



submodule etsi-nfv-vnf-deviation {




yang-version 1.1;









//DEVIATION BEGIN;




belongs-to ietf-ucpe-lne-properties {




prefix nfv;




}




include etsi-nfv-common-deviation;




//DEVIATION END;

YANG Versioning Weekly Call Minutes - 2020-11-03

We mainly discussed how Packages should work with schema mount.  Some rough=
 notes from the discussion below.

For next week we'll come up with a prioritized list of Versioning topics th=
at need broader WG input.

Rough Notes re schema mount & packages:

- if a server only advertises a single package XX, which describes a mp as =
mounting YY, then the client is guaranteed of finding YY at the mp (assumin=
g no deviations, module replacements, etc in XX).  TBD: or can the server m=
ount something else there without advertising a different package that desc=
ribes that mount ?  Can it mount ZZ that is a super-set of YY ?  Is this di=
fferent from modules because mounts are a run-time concept ?
- might need an additional flag (exact schema vs minimum-set/super-set)

- if 3 packages are listed, then at least 1 of the 3 must be mounted (and n=
o other packages besides those 3 could be at that mp) ? Is that what we wan=
t?
- if 0 packages are listed, then you have no idea (undefined)
- the mount-point info in a parent package replaces the mp info in child pa=
ckages (recursively).  This is also how conflicts are resolved.
- replacing what is available at a mp may or may not be NBC. You have to lo=
ok at all the versions of all modules at the mp before & after.
   -> TBD: what if packages foo & bar have the identical modules & versions=
.  Are they the same or different ?  Call it NBC.

Hello,

In connection to the draft
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01 I propose =
to
send a liaison statement from IETF Netmod to ORAN.

=20

The issue: 3GPP is standardizing a good number of YANG modules as part =
of
the 3gpp TS 28.541 and 28.623
(https://forge.3gpp.org/rep/sa5/MnS/tree/Rel17-draft/yang-models).=20

ORAN plans to re-use this models, but possibly refine them in some ways.
They are considering using deviations to do this.=20

E.g. change config=3Dtrue schemas node to config=3Dfalse. This creates =

-   Deviations by an SDO (standard defining organization) prevent
implementations from reporting their own deviations for the same nodes.

-   Deviations by an SDO prevent implementations from conforming to the
standards specified by both SDOs.

To avoid these problems I propose to send the following text to ORAN:

=93IETF NETMOD working group requests ORAN to avoid using deviations as =
part
of its specification. As documented in
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=
8.1
<https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01%23section=
-5.
8.1>  the usage of deviations would prevent:

*	Vendors to implement their own deviations for the same YANG schema
nodes
*	Vendors to claim conformance to both ORAN and 3GPP specifications
which are in some cases used as a base for the ORAN YANG models

Note: These problems with deviations exists even if YANG modules are =
used
without using YANG packages.

Hi Balazs,

Do you have an example of where O-RAN is trying to deviate a 3GPP model? =
I would agree that for O-RAN to deviate a model would be a problem, and =
that it should be left to vendors to decide if they want to deviate the =
3GPP model.

can help.

Hi Balazs,

=20

Do you have an example of where O-RAN is trying to deviate a 3GPP model? =
I would agree that for O-RAN to deviate a model would be a problem, and =
that it should be left to vendors to decide if they want to deviate the =
3GPP model.

to send a liaison statement from IETF Netmod to ORAN.

The issue: 3GPP is standardizing a good number of YANG modules as part =
of the 3gpp TS 28.541 and 28.623 ( =

yang-models> =
https://forge.3gpp.org/rep/sa5/MnS/tree/Rel17-draft/yang-models).=20

ORAN plans to re-use this models, but possibly refine them in some ways. =
They are considering using deviations to do this.=20

E.g. change config=3Dtrue schemas node to config=3Dfalse. This creates =
problems as documented in  =
<https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01%23section=
-5.8.1> =
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=
8.1

=20

-   Deviations by an SDO (standard defining organization) prevent =
implementations from reporting their own deviations for the same nodes.

-   Deviations by an SDO prevent implementations from conforming to the =
standards specified by both SDOs.

=20

To avoid these problems I propose to send the following text to ORAN:

=20

=E2=80=9CIETF NETMOD working group requests ORAN to avoid using =
deviations as part of its specification. As documented in  =
<https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01%23section=
-5.8.1> =
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=
8.1 the usage of deviations would prevent:

*	Vendors to implement their own deviations for the same YANG schema =
nodes
*	Vendors to claim conformance to both ORAN and 3GPP specifications =
which are in some cases used as a base for the ORAN YANG models

Note: These problems with deviations exists even if YANG modules are =
used without using YANG packages.

Hi all,

RFC8808 talks about a use-case where a network element first comes from the=
 factory.

Would it also make sense to use the factory default configuration in a scen=
ario where a device reboots but can't find the startup datastore?  (i.e. no=
 file, or corrupted file).  I think that might often be a way that a bootin=
g system would determine that it is actually in a 'new from the factory" si=
tuation.

Jason

Yes -- our server has that option (for several years).
The server can reboot with the factory default config if booting the saved
config fails.

Tom, can you review the updates to see if all your concerns were addressed?=

The YANG contact should include WG Web and WG List and Editor=0A=

Authors,

Per the 109 session, it is the chairs intent to do another adoption call =
on the "yang-node-tags=E2=80=9D draft.  In preparation for that, we=E2=80=99=
ve determined both that the draft has changed significantly and that =
there is a new author, and therefore feel it necessary to issue another =
IPR call, as follows:


Authors, Contributors, WG,

As part of preparation for WG Adoption:

Are you aware of any IPR that applies to drafts identified above?

Please state either:

"No, I'm not aware of any IPR that applies to this draft"
or
"Yes, I'm aware of IPR that applies to this draft"

If so, has this IPR been disclosed in compliance with IETF IPR rules
(see RFCs 3669, 5378 and 8179 for more details)?

If yes to the above, please state either:

"Yes, the IPR has been disclosed in compliance with IETF IPR rules"
or
"No, the IPR has not been disclosed"

If you answer no, please provide any additional details you think
appropriate.

We note that all DT members are listed as contributors.  If you
contributed to the document please respond.  Alternatively, please feel
free to state that you didn't materially contribute to the draft and
would like your name removed from the contribution section (and moved to
acknowledgments after WG adoption).

If you are listed as a document author or contributor please answer the
above by responding to this email regardless of whether or not you are
aware of any relevant IPR. This document will not advance to the next
stage until a response has been received from each author.

NOTE: THIS APPLIES TO ALL OF YOU LISTED IN THIS MESSAGE'S TO LINES.

If you are on the WG email list or attend WG meetings but are not listed
as an author or contributor, we remind you of your obligations under
the IETF IPR rules which encourages you to notify the IETF if you are
aware of IPR of others on an IETF contribution, or to refrain from
participating in any contribution or discussion related to your
undisclosed IPR. For more information, please see the RFCs listed above
and
http://trac.tools.ietf.org/group/iesg/trac/wiki/IntellectualProperty.

Thank you,
NETMOD WG Chairs

PS Please include all listed in the headers of this message in your
response.

YANG Versioning Weekly Call Minutes - 2020-11-17

We mainly discussed how Packages should work with schema mount.  Some rough=
 notes from the discussion below.

For next week we'll come up with a prioritized list of Versioning topics th=
at need broader WG input.

Rough Notes re schema mount & packages:

- if a server only advertises a single package XX, which describes a mp as =
mounting YY, then the client is guaranteed of finding YY at the mp (assumin=
g no deviations, module replacements, etc in XX).  TBD: or can the server m=
ount something else there without advertising a different package that desc=
ribes that mount ?  Can it mount ZZ that is a super-set of YY ?  Is this di=
fferent from modules because mounts are a run-time concept ?
- might need an additional flag (exact schema vs minimum-set/super-set)

- if 3 packages are listed, then at least 1 of the 3 must be mounted (and n=
o other packages besides those 3 could be at that mp) ? Is that what we wan=
t?
- if 0 packages are listed, then you have no idea (undefined)
- the mount-point info in a parent package replaces the mp info in child pa=
ckages (recursively).  This is also how conflicts are resolved.
- replacing what is available at a mp may or may not be NBC. You have to lo=
ok at all the versions of all modules at the mp before & after.
   -> TBD: what if packages foo & bar have the identical modules & versions=
.  Are they the same or different ?  Call it NBC.

YANG Versioning Weekly Call Minutes - 2020-11-24

We started by discussing the Liaison statement for ORAN:
- it is desirable to avoid ORAN mandating the *removal* of something
- it is OK if ORAN lists 'minimum' functionality
- Deviations are not allowed in Packages period (and refer to 7950 section =
7.20.3).  Not even "BC" deviations (e.g. increasing max-elements)
- Order of deviations are not defined. So if ORAN deviates and an implement=
ation deviates, it is ambiguous how the server will behave.  (should be com=
pilation error)
- we need to point towards an RFC or draft that supports what we recommend
- don't use "not" in if-feature (i.e. don't use features to turn things off=
)
- ideally point to ORAN *text*
- Balazs to send updated draft text
- Do we have a Liaison officer for 3GPP ?  IAB program. No Liaison currentl=
y for IETF <-> ORAN. Scott can help broker this.

Then we discussed setting up virtual interims.

VIRTUAL INTERIM TOPICS:

Jason to deal with interim admin (6:30am/9:30am/10:30pm) - 1 hour max
- doodle poll for days Dec 14-17 (mon-thurs)
- 20-30 mins per item and come back if time
- intro/abstract for each issue

A) Module Versioning: import by revision issues:  - Reshad
- impact of changing an import by revision
- what flavors of import by revision (greater, greater-and-nbc)
B) Module Versioning: Whitespace (interactions with Packages checksums) - J=
an
C) Module Versioning: name of file (2 file name, symbolic link, etc) - Bala=
zs
D) IANA considerations: BGP address families  <- discuss with authors first=
 - Rob

x) SemVer: mandatory for IETF ?
x) SemVer: initial version for drafts, updates, etc
x) SemVer: gaps in history, removing revision statements

Next steps:
- prepare & review slides before interims
- have interims
- on mailing list, send the final proposed decision from the interim
- LC will be the final chance for debate/change

Checksums:
- packages gives URL + SHA hash (SHA over contents)
- is checksum associated with a URL, or is it associated with a module vers=
ion
- CR/LF differences in file formats
- the publisher/owner defines what v1.0.1 is and contains

Rgds,
Jason

Hello,=20

Based on discussion here is version2 of the proposed liaison text:

=20

Liaison text v2:

=20

IETF NETMOD working group requests ORAN to avoid using deviations as =
part of its specification. When ORAN plans to reuse specifications from =
other standard bodies or industry groups it should not remove or change =
functionality.  If variations are needed compared to a base model, ORAN =
should ask the original group to include feature statements in the =
original YANG module.

=20

As documented in https://tools.ietf.org/html/rfc7950#section-7.20.3  =
=E2=80=9C... deviations MUST never be part of a published standard, =
since they are the mechanism for learning how implementations vary from =
the standards.=E2=80=9D

As documented in  =
<https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5=
.8.1> =
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=
8.1 the usage of deviations would prevent:

*	Vendors to claim conformance to both ORAN and 3GPP specifications =
(which are in some cases used as a base for the ORAN YANG models)
*	Vendors to implement their own deviations for the same YANG schema =
nodes
*	=20

Note: The problems with deviations exists even if YANG modules are used =
without using YANG packages.

I think this is an important message to O-RAN, and I know similar ideas =
have been up for discussions in other SDOs as well. I think your =
proposed way of conveying the message is good. =20

https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01 I propose =

The issue: 3GPP is standardizing a good number of YANG modules as part =
of the 3gpp TS 28.541 and 28.623 ( =

ORAN plans to re-use this models, but possibly refine them in some ways. =
They are considering using deviations to do this.=20

E.g. change config=3Dtrue schemas node to config=3Dfalse. This creates =
problems as documented in  =
<https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01%23section=
-5.8.1> =
https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=
8.1

=20

-   Deviations by an SDO (standard defining organization) prevent =
implementations from reporting their own deviations for the same nodes.

-   Deviations by an SDO prevent implementations from conforming to the =
standards specified by both SDOs.

=20

To avoid these problems I propose to send the following text to ORAN:

=20

=E2=80=9CIETF NETMOD working group requests ORAN to avoid using =

IETF NETMOD working group requests O-RAN avoid using deviations as part =

other standard bodies or industry groups it should not remove or change =
functionality.  If variations are needed compared to a base model, O-RAN =
should ask the original group to include feature statements in the =
original YANG module.

I think this is an important message to O-RAN, and I know similar ideas =
have been up for discussions in other SDOs as well. I think your =
proposed way of conveying the message is good. =20

The issue: 3GPP is standardizing a good number of YANG modules as part =
of the 3gpp TS 28.541 and 28.623 ( =

ORAN plans to re-use this models, but possibly refine them in some ways. =
They are considering using deviations to do this.=20

E.g. change config=3Dtrue schemas node to config=3Dfalse. This creates =
problems as documented in  =

https://tools.ietf.org/html/draft-ietf-netmod-yang-packages-01#section-5.=

=20

-   Deviations by an SDO (standard defining organization) prevent =
implementations from reporting their own deviations for the same nodes.

-   Deviations by an SDO prevent implementations from conforming to the =
standards specified by both SDOs.

=20

To avoid these problems I propose to send the following text to ORAN:

Hello NETMOD working group,

We are planning a one hour Virtual Interim meeting one day during the week =
of Dec 14-17 (9:30am Eastern Time).

The goal is to progress on some key outstanding decisions around the YANG V=
ersioning drafts.

### YOUR RESPONSE REQUESTED ###
Please fill in the doodle poll with what days in the Dec 14-17 you could ar=
range your schedule to attend.
- If you will, or even *may* attend, then please fill in the doodle poll
- if you don't intend to attend, then please do not fill in the doodle poll
https://doodle.com/poll/4gycdqy8if2xc4yx

The focus of this Virtual Interim meeting will be the YANG Module Revision =
Handling draft:
https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-module-versioning/

The key issues that need discussion and resolution are:
A) Behavior of import by revision-or-derived and do we need revision-or-com=
patible-derived ? Is changing the import statement a BC or an NBC change to=
 a module ?
B) Whitespace: do all whitespace changes require a bump in the revision? Co=
nsider interactions with package checksums.
C) IANA considerations: how are final RFC revision labels assigned ?
D) YANG file naming when revision labels are being used (symbolic links? @<=
revision-label>) ?

Meeting materials are being prepared and will be available for the discussi=
ons.

Some further details can be found at the following links for now:

Hi all,

We're proposing a NETMOD Virtual Interim meeting on Monday Dec. 14th at 9:3=
0am EST.

This date is tentative based on availability of some key people, and of fur=
ther confirmed interest on the doodle poll from the wider WG audience.  But=
 we wanted to announce the target date 2 weeks in advance as it currently l=
ooks like the best time to fit this in before Dec holidays.

Please see the email with subject "NETMOD Versioning virtual interim - Week=
 of Dec 14 (somewhat urgent poll)".

Rgds,
Jason
