Minutes:

MTF meeting 10/22/02


Attendees: Heather Kreger - IBM, Hao He - Thomson, Igor Sedukh - CA,
Yin-Ling Husband - HP

1.    Hao’s document comments
      ·     can’t assign namespace yet, keep for concretization later
      ·     Discovery section, in here discovery has already been done (URI
is known).
2.    Discovery conversation:
      ·     discover management ports just like other service ports are
discovered
      ·     should recommend standardization of a taxonomy to be able to
find ‘management’ ports
      ·     Do we need to tag custom management portTypes with
‘management’?
      ·     If they are compliant to standard, then it will be derived from
standard tns.
      ·     ? Service URI to management URI construction? Like
http://serviceuri/wsdl? Not sure this is viable. WSDL group defines
relationship between service and service definition
      ·     Need to define the association between the management
service/port/portTypes and the managed service/port/portTypes. Should be
able to transverse from management one to manage. Do we also need to be
able to traverse from managed to management? Probably not. ACLs could be
used to keep biz from using mgmt interfaces… is this enough? Is it bad to
be able to know what the mgmt interface is
      ·     Also secondary discovery from a managed service environment to
the services it manages and from registry to services registered. Will
service environment also list management services and ports?
3.    Operations and states
      ·     Really means status field values – not ‘state’ as in grid
services version of state (where its all service data).
      ·     We need to use standard ‘status’ values from ISO
      ·     Hao proposes that the ‘status’ field has its own URL/URI and do
get to retrieve status and post to get status. (and same goes for all
metrics) . Comments: YL: this is very fine grained, usually services are
courser grained. HK: This really should be portTypes in WSDL with bindings
to GET/POST for each data/operation. IS: Need to start more abstractly at
operation level. HH: GET/POST is more abstract. We will leave these
operations out till we concretize and then it will be one of the bindings.
In the meantime we should keep this HTTP binding in mind.
