Reference Architecture Models
With the OASIS RM 1.0 up for vote, I've found myself discussing RM/RA vocabulary again... I found a Momentum view of how we differentiate between views and their usage.
I've heard people tell me that the OASIS Reference Model has not been helpful in creating their Customer Specific Reference Architecture. Well, that doesn't surprise me - it wasn't meant to be used in that way. A reference model establishes a scope, goals and a vocabulary of abstract concepts. It is used by professional Conceptual RA developers.
In RA land there is a process of moving from very abstract to somewhat concrete. It is an evolutionary process. However, if you skip layers you'll probably find yourself confused. Professionals from OASIS have informed me that they've lost some contributors in the process of creating their specification. It doesn't surprise me - RM's are theoretical work and not for everyone. I have also been told that they intend to publish a users guide which hopefully will set the stage for its use patterns and anti-patterns. posted by jeff | 7:45 AM

Inside-out or Outside-in Just a snippet from a recent email:
Sun created a platform when they wrote an aggregated set of specifications. They made their specifications API centric. It was an inside-out view. The next generation platform must be an outside-in view centered on protocols, formats, identifiers and service descriptions. It MUST be written using RFC 2119 format.
SOA, BPM, AJAX, etc. require a new integrated outside-in standardized platform. Until then, expect limited adoption or alternatively, enterprise rework. posted by jeff | 8:15 AM
SOA Acquisitions (revised list) I've updated the list of acquisitions in the SOA space:
A few interesting notes:
1. I couldn't be more disappointed in Cisco and their lack of acquisitions. AON failed (past tense). This could go down as one of the biggest blunders in software / hardware history. IMHO, Cisco should have revisited their executive leadership around AON a long time ago.
2. I've taken Service Integrity off the list. It appears as though they've shut down and didn't move the IP. This is disappointing as well - from what I've heard, many of the SOA ISV's were never even notified that the IP was up for sale.
3. WebMethods acquired Infravio. HP/Mercury/Systinet couldn't be happier. WEBM stock has been in the gutter for a long time. Infravio has a great product and a great team. It will be interesting to see if WEBM realizes that they need to move aside and let the Infravio team run their SOA direction.
4. I'm keeping SOA Software on both 'buy side' and 'sell side'. These guys have put together a pretty interesting package that keeps them in the pure play SOA infrastructure space. It's too clean. Someone one will grab them.
5. I added a couple 'client-side' guys to the list yet: ActiveGrid and AboveAll Software.
6. I added RogueWave (strong SCA/SDO story), I will proabably add some more SDO / data service providers in the near future.
7. I added testing specialists iTKO and Parasoft (although I don't know who will buy them).
8. I added Logic Library. With the Flashline acquisition, these guys become an obvious target. posted by jeff | 5:17 AM
Shai on Enterprise SOA An excellent article identifies Shai's take on what the enterprise needs to do to prepare for enterprise SOA and the next generation SAP platform:
