I was very disappointed with this blog. There was absolutely no recognition of the OASIS Reference Model for SOA that was approved as an OASIS Standard back in October of last year. There was a cursory mention of The Open Group debate in this area, but again, no mention of the only formal, open standard SOA reference model that exists. In addition, David blended the notion of SOA "reference models" with "reference architectures" and they are clearly very different animals. Reference models are at a higher level of abstraction than reference architectures. Unfortunately, David's podcast quickly moved away from the discussion of SOA reference models and toward comparing and contrasting SOA with EA (Enterprise Architecture). This certainly is not the subject of SOA reference models. EA centers around IT Governance (as does IT portfolio management as well as IT strategic planning and roadmapping) and EA is used as a decision making tool for making capital planning and investment decisions for IT. Unlike SOA, EA is not an architectural style; certainly not an integration architectural style or application architectural style. Comparing SOA and EA is comparing apples and oranges. Again, this might make a good topic for a separate podcast in of itself but where was the breadth of coverage of the standards for SOA reference models and how come there is no mention of the only formal, approved open standard reference model for SOA---the OASIS Reference Model for SOA?
