Re: [netmod] New Version Notification for draft-lengyel-netmod-yang-instance-data-00.txt

Hello Jurgen,

IMHO once we know whether the data is config=false or true and know the datastores the server supports the datastore the instance data is relevant to is fixed. One exception is the possible loading of dynamic datastores. However as I do not have a use-case for these and we do not have any dynamic datastores defined, IMHO we can leave the usage of these datastores out of scope. If I added the following paragraphs would that help?

"If the instance data specifies config false (state data) and the server support the operational datastore, the instance data documents the operational datastore. If  the operational datastore is not supported the data documents additional state data that is stored outside the configuration datastores. The instance data MAY be used to load the relevant datastore or it MAY just be used to document its content.

If the instance data specifies config true (configuration data)  the instance data documents the running datastore.  The instance data MAY be used to load the running  datastore or it MAY just be used to document its content. While the instance data format MAY be used to load other e.g. dynamic datastores that is out of scope for this specification."

Also further clarification may be provided for each use-case in the relevant document.

regards Balazs

How do I know which datastore the data belongs to? Would it not make
sense to carry that information inline? If we do not carry this
information inline, how is that information supposed to be provided
if for example this format is used to validate examples included in
documentation?

Hello Jurgen,

I will gladly add NMDA to the draft. However could you please be more
specific. Which part of NMDA are you missing?
Is it the example of yanglib that you would like updated?

As the instance-data can be used to document and/or load    both config=true
and false data it is IMHO relevant to the candidate/running/operational
datastores. However whether it should be used to just document data or also
to load data, and how exactly such a load should be implemented  is out of
scope. And yes using one SW kit config=false data can be loaded from file
too.

[Removing NETCONF since the I-D says -netmod-.]

I flipped through the I-D yesterday and I think a common format for
instance data trees should be NMDA aware these days.

    Hello,

    With Benoit I prepared a draft about how to document and use YANG defined
    instance data. It could be useful for documenting  server capabilities or
    preloading data defined in implementation time and probably for other
    purposes as well.

    regards Balazs

  Abstract:
     This document specifies a standard file format for YANG instance
     data, that is data that could be stored in a datastore and whose
     syntax and semantics is defined by YANG models.  Instance data files
     can be used to provide information that is defined in design time.
     There is a need to document Server capabilities (which are often
     specified in design time), which should be done using instance data
     files.




  Please note that it may take a couple of minutes from the time of submission
  until the htmlized version and diff are available at tools.ietf.org.
