robin is temp tc-admin

until they recruit a new one

Administrivia

Edwards:

We are looking for a new issues editor, shall we seek a new volunteer?

everyone but Edwards and Chapman takes a step back

Vote to make new Working Draft of the Assembly V1.1 spec the next CSD (CSD07)

Edwards:

Are there any questions and are folks ready to vote?

Chapman:

Be sure that this is right as a change will require an another public review

Motion: m:Aupperle s:Jordan Approve WD 63 as CSD07 and put it out for a 15 day public review

Resolution: m:Aupperle s:Jordan Approve WD 63 as CSD07 and put it out for a 15 day public review w/o

Action: Edwards to take the appropriate steps with TC-Admin to accomplish the progression and review of CSD07

Issues against v1.2

ASSEMBLY-250: Need an equivalent to "autowire" for the eventing world http://www.osoa.org/jira/browse/ASSEMBLY-250

<anish>

eric, wondering if what you are looking for is a default composite-level channel (similar to the one that exists at the global level) -- such a default channel doesn't have to be configured by the assembler?

I don't understand the use of the term "scope" here

to me its all about visibility of channels - if yiou can see it you can use it - thats the only scoping we have

<anish>

that was my point in the presentation too -- the implementation gets to decide how the mapping to JMS topics takes place. The concept in SCA is abstract enuf to enable both cases

I think the idea of a default composite level channel is what they are asking for.. though there's then the question of whether you can elect not to have a default for a particular composite and instead have the default propagate up to the next level higher.. I have been wondering whether that would help with 227

Channels are *all* about connecting some group of producers to some group of consumers

if you have different groups then you need multiple channels

<anish>

peter, this make it complicated. such propagation/promotion was what we were trying to avoid.

<anish>

+1 to mike

if you want to limit the set of producers/consumers that can be connected, then don't put the channel at the Domain level

and you end up with a "subsystem" channel which would be entirely contained in some nested composite

<anish>

i think there may be a philosophical difference here -- I look at this as the assembler's job to figure out who is connected to whom -- this is critical. I don't think Eric/Tibco has that view.

+1 Anish - that does seem to be the case

Assembly - composition - is all about deciding what pieces there are and how they are connected

<anish>

my view is that unlike an interface contract in the service-ref world, eventing part is not conducive to 'autowire' -- you have to intentionally say who is connected to whom

I agree

next I suppose we will need to discuss channel credentials?

and while many systems may use Channels at the Domain level, there will be the need for Channels that belong to subsystems and cannot be used by components outside the subsystem (ie Composite level Channels)

i accept there is a bottom up design problem of not knowing about "local" channels in outer composites, i thought 227 and/or the concept of a virtual channel that can be bound later might solve this

Public access channels?

;-)

<anish>

i dont' see how a prosumer/label would change this issue

I believe that consumer promotion addresses Danny's composition question

<anish>

late binding requires promotion of producers/consumers/prosumers, me thinks

(& producer promotion)

propotion of a virtual channel reference

propotion

- promotion is all about enabling the assembler of a composite to decide what can be done by the "user" of the composite

<anish>

or even promotion ;-)

thanks anish

<anish>

no motion on the table, so no filibuster

four minutes

"NA Sales" vs "EMEA Sales" may be a good example of 2 channels that actually could handle the SAME event types and might require STRUCTURAL organization to distinguish

Eric J: Global Channels seem to have a radically different role to that of Composite level channels

Action: Johnson to propose more concretely what the different roles of global vs local channels might be
