New Issues

ASSEMBLY-246: Provide Location within SCA Contributions for eventType Declarations
http://www.osoa.org/jira/browse/ASSEMBLY-246

MartinC takes Chair

MikeE:

Reviews issue

...considered before, but people not happy with wording - rewritten

...Summary - No appropriate location for eventType declarations

AnishK:

Need a "pointer" to schema location from contributuions - ala schema - use a separate file for eventTypes

...can see eventTypes being defined outside contributions (either inside or outside domain)

<anish>

at the very least we need something like a .evd extension

<anish>

and maybe evdLocation attribute, but not much esle

MikeE:

Currently no way to specify anything about eventTypes

AshokM:

Thought we'd agreed to put in definitions file?

MikeE:

No - that's the point!

Motion: m=MikeE s=EricJ Open ASSEMBLY-246

No furhter discussion - No objections

Resolution: Open ASSEMBLY-246 w/o

Existing Issues

MikeE:

ASSEMBLY-227 next but no activity so will skip

ASSEMBLY-235: Remotable interface compatibility should not be restricted to a WSDL 1.1 mapping
http://www.osoa.org/jira/browse/ASSEMBLY-235

Outline Proposal:
http://lists.oasis-open.org/archives/sca-assembly/201010/msg00023.html

EricJ:

Have discussed for some time - would like to get some sort of direction from TC

...current proposal allows any IDL as long as it's the SAME on both ends of wire

...thinking of new pproposal ...

...Can allow any IDL's as long as they map to some COMMON IDL and that mapping is compatible

...(Not necessarily WSDL 1.1)

MikeE:

How is common IDL defined - how to decide what to use?

EricJ:

Don't think we can define that

...proposing that runtime may have knowledge of possible mappings and can choose

MikeE:

But then can't predict whether application will run on different runtimes

EricJ:

But do we want to force interfaces to be declared incompatible if there's not good mapping to WSDL 1.0?

MikeE:

That's not the question - what IDL do we use?

AnishK:

Thought we wanted to require mapping to WSDL to ensure interoperation

...but as pointed out current spec does not say this

DannyV:

To answer Mikes' question - mapping would be implementation defined

...possible that an application could work on on runtime and not on another

...developer would need to check runtime documentation

...I think increased compatability WITHIN runtime is preferable to increased portability BETWEEN runtimes

EricJ:

Requiring mapping to WSDL raises possibiliy of false +ve and false -ve for compatability checks

MartinC:

OK with same IDL on each end but not with using arbitary one depending on runtime

<anish>

i'll type my response to Eric here, rather than get in the Q, which is getting longer: Eric, I agree with you wrt false +ve/-ve. That is a compromise to get to a common IDL (WSDL 1.1) -- which would be the lowest common denominator

<anish>

currently we define compatibility is such a way that already allows for false +ve/-ve

MikeE:

Vendor could support Eric's idea, but should be outside standard and not "accommodated" in spec

sounds good to me

EricJ:

Compromise - Can't map any two IDL's to a third and claim compatible

would (either of) the interface specs say that there is such a mapping?

...could allow IDL on one end to map to the other IDL (or WSDL)

<anish>

couldn't that be defined in the spec for <interface.foo>?

Anish: I would be OK if the spec for <interface.foo> defined the mapping

...runtime would have to decide on what mapping to use

AnishK:

Mapping for interfaces should be portable IFF the interface is support by runtime

MikeE:

Mapping should be portable between runtimes - otherwise not part of spec

Note Diane Jordan for role

EricJ:

Would be happy to make another proposal but need a direction from TC

Time - 2 minutes

AOB

Straggler role

Anish Karmarkar, Diane Jordan

Thanks Eric

Bob - my condolences

Mike exhorts people to thrash out ASSEMBLY-235 on list

roll is fixed: http://www.oasis-open.org/apps/org/workgroup/sca-assembly/event.php?event_id=28479

;-) nicely put Eric

thanks Eric W

Meeting adjourned 9:00AM PDT

EricW:

NP - I should be able to get the minutes out later today

...Tools aren't completely working but far enough to tweak the o/p by hand where needed
