Title: Re: [soa-rm-ra] FW: Updated SOA Harmonization draft from 4/17 call

To elaborate more – this figure is meant to explain the inter-relations between various artifacts in the SOA standard world (although it could equally be used for any architectural domain).  Heather really put it together for all of us IMO and this nicely represents OMG, TOG and OASIS as well as potentially mapping to standards used for implementing SOA such as W3C, OASIS, ISO and other bodies work.

Hi Eric, 

Thanks for applying some deep thought to this ... 

From the call last week I was picturing in my head something like this... (I'm sure Ali will have something much more elegant and this may not be exactly what he's thinking) .. where we just positioned the architecture specs we're actually working on in Fig 2..... 

I may not have the relationship names right (suggestions welcome) but you get the idea ... 

We don't really talk about the relationship of the reference architecture to the implementation and given the discussion on the call it sounded like we were all comfortable removing the SOA implementation layer from the original fig. 2.   So I'm not sure we need the Logical/Physical/Implementation aspects captured here in the diagram. 

Are you suggesting this text as the replacement for The Open Group definition only? or as a definition that OASIS would agree to as well.  I don't really see the spirit of the OASIS definition represented here... 

While I, as an IBMer, appreciate the example, we might want to pick a standards based one rather than ESB just to avoid contention :-)

Is including the logical and physical architectures needed for the level of resolution this diagram is to support?

Heather, 

Attached please find the New Fig.2 diagram.  The text of the previous version still stands. I have only changed the diagram.

Eric, can you send this diagram in .ppt? I can't open .pptx 

Are you proposing the text after the Fig as part of your proposed wording?

Ali and the Team, 

Here’s some points that I raised in last Friday’s Harmonization call. It seems to me, we are having trouble defining conciselywhat an SOA Reference Architecture is and how it interplays with other objects in the space.  I suggest that the attached slide or a variation thereof should replace Fig. 2 of the document.  In a nutshell: 

A Reference Architecture (RA) is an instantiation of a grouping of one or more generic Architecture Patterns for a given domain, such as SOA. Applying  a project-specific set of SOA requirements to the RA will generate a Solution Architecturefor those requirements, resulting in an SOA Logical Architecture and an SOA Physical Architecture, respectively.  The latter would serve as the basis for the SOA implementation. 

  

  

An Example: IBM chose the ESB architecture pattern (a generic pattern known for about two decades even before the term SOA had been coined) as the basis for its SOA Foundation Reference Architecture.  Then from that point on,  any new SOA project will be an instantiation/customization of the SOA Reference Architecture. For example, a specific project may not have any requirements for Information as a service or interaction with corporate partners, in which case those components  of the SOA RA will be dropped, and so on. 

  

Incidentally, I have applied this framework to some of the largest SOA implementations in the world at the United States Air Force and it works J 

I hope this helps.

Eric Dabbaghchi

Hi folks, 

Here's an update of the SOA Harmonization document draft based on todays discussion. 

I accepted the edits in the sections we reviewed, updated the continuum picture to include foundation SOA RAs .. and positioned the RA's we are working with. 

I also dropped in the contents of the SOA Concepts note .. I thought it would be easier to collaborate and comment/edit here. 

I have not tackled the guidance section yet.
