Subject: Re: [sca-assembly] Any agenda items for tmorrow's SCA Assembly conference call?


Jim,

I agree that separation of Asm and Policy is *possible*. I would argue that:
1) it is not desirable,
2) it is not easy (from a spec POV, not from the POV of a particular implementation), there is plenty of work involved there.
3) by design, asm and policy are joined at the hip/intertwined.

The only reason they are different specs, done in different TCs, is for administrative reasons. The skill set and interest required for participating in assembly and policy are/were different. There certainly were folks that were interested in both. But enough folks were just interested in policy or just asm to make it an administrative problem in terms of attendance, quorum etc.

I view asm and policy as a single spec divided into two parts for convenience/manageability.

Ashok,

First, separating Assembly and Policy is possible and it is not hard to
achieve technically speaking. Fabric3 has already done this as both
Policy and WS Binding features can be removed from the runtime by simply
deleting three JAR files. Architecturally, Policy and WS Binding support
are added to Fabric3 via OSGi-based modularity.This allows for a
separation of concerns that, in my opinion, should also be reflected in
the specifications.

Second, we haven't discussed this before with the benefit of actual SCA
implementation experience. This is an issue that has the support of at
least Fabric3, Siemens, and TIBCO. It's worthy of discussion and not a
waste of time.

I'm sorry you feel this topic is not a productive use of your time and
have nothing to contribute to the technical discussion.

    We have discussed this before.  SCA Assembly and SCA Policy are
    intertwined and hard to separate.
    We also discussed the separation of Assembly from the WS Bindings
    and, after a long discussion,
    decided against it.  There is no new news.  Let's not waste our time.
    All the best, Ashok

    Hi,

    I would like to have an item placed on the agenda to discuss
    removing the dependencies on the SCA Policy and SCA Web Services
    Binding specifications from the Assembly specification. I have
    discussed this already with some TC members but it would be good
    to begin wider discussions.
