Title: [Omod] Oct 28 call agenda


1. Roll : 
Heather, FredC, William, Zulah, BrianM, Alexandro, MarkP, 
Andrea

2. Approve corrected minutes 
http://www.oasis-open.org/archives/wsdm/200310/msg00113.html  

approved. 

3. Review action items 

ACTION: Fred to 
provide text for the ISSUE 3. (aggregation 
of manageability to the endpoint level is a responsibility of the provider of 
manageability) [http://www.oasis-open.org/archives/wsdm/200310/msg00122.html] 

Fred presented his proposal.

[brief discussion & clarifications not 
captured]

DECISION: use Fred's proposed text for the issue 3 and 
close the issue

ACTION: 
William to provide text on inferring manageability of a service from manageable 
endpoints (generally, no specifics of how) 

William presented his 
proposal.

Group decisded to postpone discussions until 
everybody's got a chance to review the 
text.

ACTION: 
BrianC to align the versioning/revision/change detail UML diagram with the MOWS 
Concepts diagram and incorporate "versioned X is an X" elements. 

posponed 

4. Review 
issues 
ISSUE 5: 
using http://lists.oasis-open.org/archives/wsdm/200310/msg00067.html UML approach 
ACTION: BrianC to attempt to express 
ManageableEndpointState UML information model linked directly to the web service 
endpoint state diagrams designed by the W3C Arch MTF. See http://www.oasis-open.org/archives/wsdm/200310/msg00084.html

Igor's simplified 
proposal: http://lists.oasis-open.org/archives/wsdm/200310/msg00082.html and other possible 
choices http://lists.oasis-open.org/archives/wsdm/200310/msg00083.html  

Igor presented the 
proposal.

Heather: 
how is the optionality represented?

Igor: by 
cardinality of an element [0..1] means optional [1] means 
mandatory

Heather: 
what do +/- mean?

Igor: 
writeable and read-only properties.

Heather: 
thought that +/- represented optionality.

Mark: 
wants UML 2.0 compliance of the diagram, and no problems 
otherwise

Fred: UML 
2.0 says that readonly must be represented by a 
{constraint}

Igor: 
yes, but it clutters the digram a lot

Mark: 
agrees

Igor: 
read only can be represented by a stereotype <<ro>>, although that 
would make it look like an <<event>> and may raise some 
questions.

Mark: 
would the group agree to use this approach as long as it is UML 2.0 
compliant?

No 
objections.

ACTION: 
Igor to research how to pretty-up the presented UML diagram to be UML 2.0 
compliant with respect to readonly modifier and research how to hide +/- if 
they are not used in the diagram.

ISSUE 
6: There is a need for another 
diagram to display the "locus of implementation" concepts. 
Essentially the diagram to depict relationships between 
manageable endpoint in MOWS Concepts and manageability endpoint in 
MUWS. 

ACTION: Igor to 
provide "locus of implementation" concepts diagram for MOWS. 
See http://www.oasis-open.org/archives/wsdm/200310/msg00076.html  

Igor: presented 
the diagram.

The diagram itself did not raise concerns, 
but...

Heather, Zulah: need some text to match the diagram, 
text in the e-mail won't do.

Fred: sent the proposed text to the WSDM 
list and quoted it to the group.

Igor: is it ok to move on agreeing to use the diagram 
and Fred's text to close the issue 6.

Group did not object, Mark wanted to read the text in 
the e-mail.

Issue stays open until e-mail discussion on the Fred's 
text confirms that it is ok to close it.

ISSUE 
7: another diagram that shows 
relationships of MUWS and MOWS concepts (possibly aggregation/composition of 
manageability capabilities).  

Igor: issue was raised after the drafting of the MOWS 
concepts diagram F2F in Cupertino. If we combine MUWS + MOWS concepts 
diagram and a proposed sample manageability capability diagram discussed for the 
issue 5, we get everything necessary. Not sure why anything else is necessary. 
Combined the diagrams express that MOWS manageability capability "is a" MUWS 
manageability capability and a manageable endpoint may aggregate many 
manageability capabilities of MOWS and MUWS kinds. That should be 
sufficient.

Igor: this issue could be retired (closed with no actions 
on it).

keep open until Zulah's input 

ISSUE 8: performance vs metrics: can we stick to slide 17 or should 
the category be renamed to "Performance" instead of "Metrics" See e-mail 
thread.

DECSION: move this discussion to UArch and for now stick to 
categorization expressed on slide 17

ISSUE 9: need to start the document with concepts + 
models 

Igor: 
intention is to stitch the information (diagrams & text) that we have 
discussed and had recorded the consensus about into a document so that we can 
(1) keep discussions consistent (2) deliver an adqueate output of this task 
force

 

discussed whether we need a separate document or can start MOWS document 
and fill in the details

DECISION: start the MOWS document

 

ACTION: Igor to start the MOWS document outline and 
fill in the parts that we have already dicussed and recorded the decisions 
for (e.g. diagrams, text in 
e-mails)
 

Igor: we need to produce models with actual props/events/ops 
by Nov 1st and so far we have discussed all the peripheral stuff as we had to 
move back to basics. To deliver we need to work on concrete proposals on our 
next call. Earlier I have provided WS-Manageability models forematted in the 
framework of MUWS/MOWS concepts (http://lists.oasis-open.org/archives/wsdm/200310/msg00067.html). We can either use it as a starting point and add/remove or have 
a similarly expressed other proposals that we can combine into one 
model.

Heather: is there a way to provide a similar model for WSMF so that we 
can be comparing apples to apples?

William kindly agreed to provide a model for WSMF.

ACTION:  William to provide a model 
of WSMF managing a web service endpoint expressed in UML similarly to http://lists.oasis-open.org/archives/wsdm/200310/msg00067.html

ACTION: Igor to send visio file to William.

Plan for next call: discuss the document and model 
proposals so that we can combine them

 Note: other issues are retired until 
reoccurance. Decsions were made and action items taken on the retired 
issues.
