[Ralph Niederberger]

This is the draft version of the meeting notes for the March 3rd, 2009 
meeting
of NML-WG second session at OGF 25, 14:00 - 15:30 CET.

Please give comments and corrections.

About 20 attendees have been present (please check)

NML-WG Schema Definition Document
=================================
   Curently the following structure has been proposed and the persons
   giving/collecting input have been proposed
     - Introduction <- Jeroen van der Ham & Martin Swany
     - Schema <- Jeroen & Martin
     - Identifiers <- Lars Fischer
     - non-normative use examples <- Fred Dijkstra
   The original supposed chapter "Syntax" will be handled in a different 
document
   Document should be in Latex, so that no real editor is needed
   First draft to be ready at OGF26

Identifier discussion (urn:ogf:network:...)
===========================================
   Email to Joel Repogle by Richard Hughes-Jones & Jeroen for registration
   Joel will contact IANA for urn:ogf:network naming scheme

Issues tracker (responsible Freek)
==================================
   - NSI Issues (John Vollbrecht & Freek)

Slides of meeting will be put online by Martin & Jeroen
=======================================================
  
Minutes of session will be provided by Freek and Ralph Niederberger
===================================================================

Latex SVN repository (responsible Freek)
========================================

Freek made a short proposal
===========================
   Use cases are high level
   Freek would like to have a repository of use cases
   Describe small use cases e.g. a named link having a different name
      than its interfaces connected to the link

Presentation: Network Services Interfaces by John Vollbrecht
============================================================
   Status of NSI
      Generating a use case document & architecture document
   Concerning Architecture WG bi-weekly VC call since January
   A lot of issues found. See presentation for details
   Discussion led to set of "Issues documents" which provide info about 
thouhgts and decisions
   See:

      
http://forge.gridforum.org/sf/docman/do/listDocuments/projects.nsi-wg/docman.root.drafts

   NSi & NML collaboration in naming conventions is needed and desirable
   Many similarities and work items, so:
   Suggestion that NML and NSI have formal collaboration
   NSI-WG is working on Connection Oriented Network Service interface 
(Co-NSI) currently
   Requestor agent communicates with CO-NS agent via CO-NSI.

   Network Service Data Planes are connected via Link Connection 
Segments in
      a Multi-Domain Network Service.
   Data connections cross multiple Network Services

   Next Steps:
   Work on model of Network Service
   Work in user cases and how to describe them
   Create Architecture document by OGF268
   Define required collaborations: NML, Security, Job Scheduling, others?
       Suggestions/Questions by audience:
             Which kind of security?
             What about Accounting and Authorization of Requesting 
ressources?
       Answers: Yes, these are also things to think about.
   How should collaboration be organized?
     - Send requests to NML or
     - direct discussion (e.g. live issue tracker)
     -> Wiki should be used

Freek announces a "Terminology table"
==========================================   
    This document is available via Gridforge.
    (only informational, that different standards use different 
terminologies
     and for checking, which terminology to use when talking to each other)

best regards

Ralph
