  WG status review (15 minutes) David Partain
	we are in good shape; most documents on time.
	architecture and DSDL draft a bit behind



  Session goal: Conformation of consensus reached at interim meeting and on ML:

       1. NETMOD Architecture 
           Phil Shafer (15 min)
           http://tools.ietf.org/html/draft-shafer-netmod-arch-00         
           3/4 of the room have read this
           significant list of comments have not been addressed yet
           consensus to accept as WG draft, with required changes

       2. Common YANG Data Types 
           M. Bjorklund  (5 min)       
           http://tools.ietf.org/html/draft-ietf-netmod-yang-types-01
           slides: http://www.ietf.org/proceedings/08nov/slides/netmod-4.pdf

       3. YANG - A data modeling language for NETCONF 
           M. Bjorklund (40 min)
           http://tools.ietf.org/html/draft-ietf-netmod-yang-02
		This presentation will include YIN and XML deliverables (40 min)
           slides: http://www.ietf.org/proceedings/08nov/slides/netmod-3.pdf
           Discussion of changes to document since last version.
           Canonical form: consensus to return the canonical form to allow comparisons
           Refinement, when, and augment: consensus to accept
           Features: consensus to accept this feature
           Deviations: consensus to add this to document deviations from standard
               agent-capabilities in SNMP failed, but adding this in the beginning might work
           Identity and identityref: reusable enumerations 
           Update rules: two basic rules: protect old clients, import by revision
               draft contains long list of specific update rules 

       4. Mapping of YANG to DSDL
            Ladislav Lhotka (15 min)
            http://tools.ietf.org/html/draft-lhotka-yang-dsdl-map-01 
            slides: http://www.ietf.org/proceedings/08nov/slides/netmod-0.pdf
            MP3: ~54 minutes into MP3
            description of how DSDL fits in the architecture:
                single full output DSDL "supermodel" or individual models
                supplemented with XSLT to generate validation rules
                the supermodel will largely be dependent on device support
                individual models (CF: single yang models) doesn't make much sense
                extension mechanism if very different than yang extension mechanism
                cannot keep same modularity as in yang
                expectation was that modularity would be the same, similar to MIB
                consensus to build individual module translations, if possible
                Lada will try to do this, and discuss further tomorrow
                if DSDL cannot do this, then maybe we should scrap DSDL
                DSDL is designed to do validation, not data modeling
             positioning: charter calls for a mapping from YANG to DSDL
                YANG is normative; DSDL converts to machine-friendly format
                One way mapping from YANG to DSDL; no DSDL-to-YANG mapping
            consensus to adopt this as a WG draft
                need ML confirmation

  Open mic (30 minutes) 
    New co-chair; 
       David H resigned as co-chair to work in other areas; 
       David Kessens is new co-chair

    Interim in Malta: netmod not interested; 
       IESG cancelling Malta meeting
       Desire to improve virtual meeting support

    ML consensus is enough is enough
       Chairs declare consensus that new features will not be accepted 
       after this two-session meeting. Consensus must be reached by close of
       meeting on Friday to be accepted for yang 1.0.    
       Focus should be to get documents completed.
       Targeting WGLC following next IETF meeting.
       We need fresh eyes to review to verify we are on the right track
       Feature freeze is in effect

Session goal: Open Issues in NETMOD, and proposals for added functionality

  Open issues and questions for YANG/YIN/XML/LIB - Martin (60 min)
  slides: http://www.ietf.org/proceedings/08nov/slides/netmod-5.pdf
  how do we represent canonical form? consensus - alternative 3

  conformance: consensus - wait until later release
  schema discovery format: consensus - Yang draft must say how and 
       what to advertise in the hello message
  inline rpc errors: concensus option 2
  assigned-by: consensus - add this
  create-only for leafs: no consensus
  actions: no consensus to add this
