Action Items
OGSI IPR policy
... nothing back from Philippe regarding his inquiries with W3C officials
sgg to follow up with Philippe, re:
OGSI IP email
CORBA IDL Attributes
... Jeff M. of Oracle to discuss CORBA IDL attributes on June 30
Discussion
of OGSI Requirements
will be deferred
until David Snelling can be on the call
Modelling Attribute
accessor operations in WSDL language
... umit:
are we trying to do a state model or just model attributes in WSDL
... stateful web services is being discussed in ws-arch
... stateful interactions vs state on the server
itself
... OGSI tends to lean towards stateful instances
... BPEL is more aligned with stateful interactions
... should we clarify the use cases to distinguish stateful interactions vs stateful instances
... are we going to suggest a transaction model as being required?
... ogsi did not require transactions
... systems management seems to also come to the same conclusion regarding
transactions
... ejb 2.0 required transactional context
… Essentially, we are
asking 2 questions:
... should wsdl tell you how to access attributes?
... second question, should wsdl use operations
... answer to first question seems to be yes
... we should come up with an alternative to operations?
... we would need to specify the means to access the attributes without forcing
an interace or operation set
... william proposes: interface defines the
attributes
... and the bindings defines the mechanisms by which attributes can be
read/written/queried
... some model of attributes needs to be in the core WSDL language
... so what does that mean?
... at the abstract level what the attributes are?
... what about how attributes are accessed
... william: argue they should be both
... umit: should be both
... sgg: +1
... solve the problem at the minimal level
... if you were to add an interface: this is what it looks like
... define two workable approaches
... one that includes operations
... one that describes access at the binding level
... start with a conceptual model
... put as much information in the requirements as possible
Schedule for next several weeks
… Steve will be absent
from the June 30 teleconference, and most likely from the July 7 teleconference
as well
… Steve will post reminder for the June 30 call, but not the July 7 call
… June 30 we will review CORBA IDL Attributes and review OGSI requirements
… July 7, Jim Amsden from IBM will discuss WebDAV
… by July 14 we should begin assigning some writing in preparation for
the July F2F
… we should have a requirements section, with a review of a conceptual
model, and then a proposal that models
… access to attributes at the abstract level and a proposal that models
access to attributes at the binding level.
… Umit expressed concern that multi-attribute
query will be our most challenging concept to work up. All agreed.
