Page 5 Copyright © 2010 Data Access Technologies, Inc. Model Driven Solutions May 2009 SOA Mythology Your going to find services on the internet and run them dynamically –We vet our service partners carefully, finding is not always important The point of SOA is reuse of technology –The point is enabling collaboration to achieve business value –If you can reuse that or pieces of it, GREAT! Reuse requires planning! Each service is independent –Services are meaningful in a context that may involve many services SOA is about technology, processes are about business –SOA is about people, organizations and systems collaborating – it is a way to understand business federation, facilitated by technology –Likewise, BPM has technology and business aspects You can just start exposing capabilities as services –An architecture puts the services in context to provide business value

Model Driven Solutions May 2009 SOA & Architecture for Open Government Transparency –Transparency means visibility of information, this information includes the processes, resources, services, data descriptions and policies of government. This information is captured in various kinds of architecture, the most useful being architectures as models Collaboration –Collaboration requires an understanding between independent parties, we have to understand what each has to offer in a common vocabulary and the rules of engagement, captured in architectures Participation –Participation is transparency with collaboration. Moving beyond human to human networking will require architectural data about how to participate You can only leverage what you understand!

Page 12 Copyright © 2010 Data Access Technologies, Inc. Model Driven Solutions May 2009 Information This means zero or more This means one or more This indicates a compositional (as opposed to referential) association. This is a constraint that defines the sub-classification. A term in the vocabulary represents a class of things to be described. Attributes specify descriptive information having simple types. Entities may be described as having a unique identity. A relation between terms is described by an association between classes. A class may be specialized into sub- classifications. An un-shaded class is not detailed on this diagram.
